1 00:00:00,320 --> 00:00:02,880 Speaker 1: Brought to you by the reinvented two thousand twelve camera. 2 00:00:03,200 --> 00:00:09,039 Speaker 1: It's ready. Are you get in touch with technology? With 3 00:00:09,119 --> 00:00:17,720 Speaker 1: tech Style from how stuff works dot com. Hello everybody, 4 00:00:17,720 --> 00:00:19,960 Speaker 1: and welcome to tech stuff. My name is Chris Poulette. 5 00:00:19,960 --> 00:00:22,320 Speaker 1: I'm an editor here at how stuff works dot Com. 6 00:00:22,320 --> 00:00:25,440 Speaker 1: Sitting across from me as usual as senior writer Jonathan Strickland. 7 00:00:25,520 --> 00:00:29,240 Speaker 1: Hey there, Crispy, So what do you want to talk 8 00:00:29,280 --> 00:00:34,920 Speaker 1: about today? Today? I want to talk about um flying? Okay, 9 00:00:35,200 --> 00:00:38,040 Speaker 1: you know, wait, we did our podcast about cell phone 10 00:00:38,120 --> 00:00:40,879 Speaker 1: safety and whether or not it was safe to actually 11 00:00:40,920 --> 00:00:43,559 Speaker 1: have a cell phone working on a plane, and then 12 00:00:43,600 --> 00:00:45,520 Speaker 1: it occurred to us that there's a lot of really 13 00:00:45,560 --> 00:00:50,560 Speaker 1: cool technology that planes use to not only take flight, 14 00:00:50,640 --> 00:00:53,280 Speaker 1: but to get around to where they're going, and we 15 00:00:53,360 --> 00:00:56,240 Speaker 1: kind of wanted to touch on some of the systems. No, granted, 16 00:00:56,640 --> 00:01:02,040 Speaker 1: a a really detailed discussion about airplane technology would probably 17 00:01:02,080 --> 00:01:03,920 Speaker 1: take hours and hours, so again, this is going to 18 00:01:04,000 --> 00:01:06,880 Speaker 1: be an overview, but we're gonna hit some of the 19 00:01:06,480 --> 00:01:09,120 Speaker 1: uh the cool technology that gets you to where you're 20 00:01:09,120 --> 00:01:11,240 Speaker 1: going when you're taking flight. Yeah, some of it's really 21 00:01:11,240 --> 00:01:14,319 Speaker 1: really complicated. Other parts of it are just plane simple, 22 00:01:15,280 --> 00:01:20,920 Speaker 1: ha ha. Alright, So with that in mind, let's go 23 00:01:20,959 --> 00:01:23,360 Speaker 1: ahead and get started. Did you have something in mind 24 00:01:23,400 --> 00:01:25,240 Speaker 1: to start with. I was going to talk about sensors 25 00:01:25,319 --> 00:01:28,160 Speaker 1: for because sensors you know, this is of course this 26 00:01:28,240 --> 00:01:30,120 Speaker 1: is these are all the systems on the plane that 27 00:01:30,319 --> 00:01:32,959 Speaker 1: tell it where it is, how fast it's moving, what's 28 00:01:32,959 --> 00:01:36,160 Speaker 1: its relationship with other stuff that's in the area. And 29 00:01:36,200 --> 00:01:38,399 Speaker 1: it's all obviously very important for the safety of the 30 00:01:38,400 --> 00:01:41,560 Speaker 1: plane and for navigational purposes. And there are tons of 31 00:01:41,600 --> 00:01:43,920 Speaker 1: different kinds of sensors that we can talk about, but 32 00:01:44,000 --> 00:01:47,640 Speaker 1: in general, the ones that are pretty much standard across 33 00:01:48,320 --> 00:01:51,400 Speaker 1: pretty much any plane of significance would be you'd have 34 00:01:51,440 --> 00:01:55,160 Speaker 1: to have something that keeps time right, so a clock 35 00:01:55,320 --> 00:02:01,360 Speaker 1: of some sort um you iCal device, US econological device, 36 00:02:01,440 --> 00:02:06,520 Speaker 1: and altimeter, which in general uses measures air pressure and 37 00:02:06,560 --> 00:02:12,000 Speaker 1: determines how um how high up you are, UH, something 38 00:02:12,040 --> 00:02:16,519 Speaker 1: that can can detect and measure air speed UM and 39 00:02:16,720 --> 00:02:24,200 Speaker 1: definite accelerometers both for vertical acceleration and horizontal UM. A 40 00:02:24,320 --> 00:02:28,600 Speaker 1: compass of some sort so magnetic heading. You would need 41 00:02:28,960 --> 00:02:33,160 Speaker 1: some sensors that would be able to uh indicate where 42 00:02:33,240 --> 00:02:35,920 Speaker 1: the controls are, I mean, like what what setting they 43 00:02:35,960 --> 00:02:39,600 Speaker 1: are in obviously UM fuel sensors, that kind of thing, 44 00:02:40,000 --> 00:02:44,760 Speaker 1: UH stabilizers. UM. All these sensors are very very important 45 00:02:44,800 --> 00:02:48,320 Speaker 1: so that the pilot can make sure that everything is 46 00:02:48,320 --> 00:02:51,239 Speaker 1: is UH as it should be and or make adjustments 47 00:02:51,240 --> 00:02:55,399 Speaker 1: if things aren't quite right. And they also the equipment 48 00:02:55,440 --> 00:02:58,200 Speaker 1: that needed to judge the state of the aircraft, like 49 00:02:58,240 --> 00:03:02,160 Speaker 1: where the flaps are, the wheels, and all the other 50 00:03:02,240 --> 00:03:04,880 Speaker 1: things that need to move, how much gas is in 51 00:03:04,880 --> 00:03:09,200 Speaker 1: the tank jet fuel jet fuel. Yeah, well, you know, 52 00:03:10,200 --> 00:03:12,440 Speaker 1: we can simplify a little bit. I think I think 53 00:03:12,440 --> 00:03:15,720 Speaker 1: we'll only get maybe ten or fifteen listener mails if 54 00:03:15,720 --> 00:03:20,000 Speaker 1: we do that. UM. But yeah, all of this information 55 00:03:20,240 --> 00:03:24,680 Speaker 1: gets fed UH to a flight data recorder as well 56 00:03:24,720 --> 00:03:29,080 Speaker 1: as to the instruments on the pilot's console. And the 57 00:03:29,120 --> 00:03:32,919 Speaker 1: flight data recorder is very important in the case of UH, 58 00:03:33,320 --> 00:03:38,000 Speaker 1: something unusual happening, whether it ends up being an actual accident, 59 00:03:38,160 --> 00:03:40,360 Speaker 1: which you know hopefully that's not the case, or if 60 00:03:40,400 --> 00:03:43,000 Speaker 1: just something is not quite right and then they need 61 00:03:43,040 --> 00:03:45,960 Speaker 1: to review it at the end of the flight. UM. 62 00:03:46,280 --> 00:03:49,760 Speaker 1: And the flight data recorder is located along with the 63 00:03:49,840 --> 00:03:54,000 Speaker 1: cockpit voice recorder in UM in special a special kind 64 00:03:54,000 --> 00:03:57,120 Speaker 1: of casing, and there's a very common term for this 65 00:03:57,200 --> 00:04:01,960 Speaker 1: kind of casing. It's actually a very deceptive term. Considering 66 00:04:02,000 --> 00:04:06,320 Speaker 1: what looks like a really sturdy box, well, it's called 67 00:04:06,320 --> 00:04:08,920 Speaker 1: it usually a black box, even though they're not black, right, 68 00:04:08,960 --> 00:04:11,680 Speaker 1: they're not black, and they don't really look like boxes. Necessarily. 69 00:04:12,080 --> 00:04:16,000 Speaker 1: They're usually bright orange UM because it makes it easier 70 00:04:16,040 --> 00:04:21,719 Speaker 1: to spot if again, the unfortunate conclusion of a wreck occurs, 71 00:04:22,360 --> 00:04:25,760 Speaker 1: if you've got a lot of wreckage, right, orange container 72 00:04:25,960 --> 00:04:29,920 Speaker 1: stands out black not so much, especially there's been fire damage. 73 00:04:30,720 --> 00:04:34,640 Speaker 1: So the black box, as they're known, UM, they shield 74 00:04:34,880 --> 00:04:37,560 Speaker 1: the flight down of recorder and the cockpit voice recorder. 75 00:04:37,560 --> 00:04:40,960 Speaker 1: Actually there's often two different ones, one for each, and 76 00:04:41,000 --> 00:04:43,640 Speaker 1: they're most often in the very back of the plane 77 00:04:43,640 --> 00:04:45,560 Speaker 1: and the tail of the plane because that's going to 78 00:04:45,600 --> 00:04:48,000 Speaker 1: be the area of the plane that suffers the least 79 00:04:48,040 --> 00:04:52,039 Speaker 1: damage in case of an impact in most cases. Yep 80 00:04:52,400 --> 00:04:55,880 Speaker 1: and UM. Actually, the information that goes to these machines 81 00:04:56,080 --> 00:04:58,960 Speaker 1: is collected by the flight Data Acquisition Unit, which basically 82 00:04:59,000 --> 00:05:02,400 Speaker 1: is a go between UH for the sensors and the 83 00:05:03,000 --> 00:05:06,160 Speaker 1: black boxing. I'm still making a case that boxing should 84 00:05:06,160 --> 00:05:08,840 Speaker 1: be the plural for box. Well, I mean, you got 85 00:05:08,960 --> 00:05:15,240 Speaker 1: good luck that anyhow, They basically have two separate responsibilities. 86 00:05:15,279 --> 00:05:20,480 Speaker 1: The the cockpit voice recorder is used to record the 87 00:05:20,600 --> 00:05:26,680 Speaker 1: voices in the cockpit. You don't say, I do say? Um, 88 00:05:26,760 --> 00:05:30,120 Speaker 1: so yeah, basically all the all the communications in the 89 00:05:30,160 --> 00:05:32,800 Speaker 1: cap and you know, in the actual cockpit itself, between 90 00:05:32,839 --> 00:05:36,680 Speaker 1: the pilot and anybody else who happens to be in there, right, 91 00:05:36,720 --> 00:05:40,120 Speaker 1: the co pilot and maybe another and anyone else who 92 00:05:40,240 --> 00:05:44,120 Speaker 1: actually is in the cockpit. Sometimes there are three yeah, 93 00:05:44,240 --> 00:05:49,039 Speaker 1: officers in the cockpit or um and usually they it's 94 00:05:49,080 --> 00:05:53,120 Speaker 1: taking taking a sound from the microphones that are located 95 00:05:53,160 --> 00:05:56,640 Speaker 1: in the pilot's headset, that copilots headset. There's usually also 96 00:05:56,760 --> 00:05:59,960 Speaker 1: another microphone that's in the cockpit itself. It's not connect 97 00:06:00,120 --> 00:06:02,000 Speaker 1: to a headset. It's just there to pick up any 98 00:06:02,040 --> 00:06:06,039 Speaker 1: other sounds and its warnings for example, right yeah, and 99 00:06:06,040 --> 00:06:08,200 Speaker 1: it'll pick up like if there's a loud thud or 100 00:06:08,279 --> 00:06:11,119 Speaker 1: something along those lines. I mean, it'll that will help 101 00:06:11,680 --> 00:06:18,120 Speaker 1: people figure out what happened after the event. So um yeah, 102 00:06:18,279 --> 00:06:20,960 Speaker 1: everything that that goes on in the cockpits recorded there. Now, 103 00:06:21,080 --> 00:06:24,440 Speaker 1: what's interesting is that, uh, it doesn't keep all that 104 00:06:24,480 --> 00:06:28,919 Speaker 1: information forever. No, it actually, uh, depending on the the 105 00:06:28,960 --> 00:06:33,080 Speaker 1: media upon which the voices are recorded. It will keep 106 00:06:33,120 --> 00:06:37,800 Speaker 1: that for between thirty minutes and two hours. And in 107 00:06:37,800 --> 00:06:40,360 Speaker 1: most cases now I think most of them have used 108 00:06:40,760 --> 00:06:44,880 Speaker 1: solid state tape solid state technology, can I not say that? Right? 109 00:06:45,080 --> 00:06:48,920 Speaker 1: More times? Basically they used to use real to real 110 00:06:49,839 --> 00:06:54,000 Speaker 1: tapes magnetic tape, um, you know, which has a finite 111 00:06:54,000 --> 00:06:58,360 Speaker 1: beginning and end. Uh. The solid state flash type memory 112 00:06:59,120 --> 00:07:02,360 Speaker 1: has the ability to you know, keep racing and um. 113 00:07:02,400 --> 00:07:05,159 Speaker 1: You know, it's also got the advantage of not having 114 00:07:05,200 --> 00:07:09,200 Speaker 1: as many moving parts, right, yeah, it's it um also 115 00:07:09,279 --> 00:07:11,840 Speaker 1: not uh yeah, it's not as vulnerable to damage as 116 00:07:11,840 --> 00:07:15,240 Speaker 1: the magnetic tape is necessarily I mean, and U it 117 00:07:15,280 --> 00:07:18,080 Speaker 1: can hold a lot more information to in a in 118 00:07:17,560 --> 00:07:22,600 Speaker 1: a in the same physical amount of space. So yeah, 119 00:07:22,800 --> 00:07:24,760 Speaker 1: up to two hours, maybe even more than that. Actually 120 00:07:24,760 --> 00:07:26,840 Speaker 1: that the latest I saw was two hours, but I'm 121 00:07:26,840 --> 00:07:29,520 Speaker 1: guessing that you know, with the way that that solid 122 00:07:29,560 --> 00:07:32,000 Speaker 1: state drives have have advanced over the last few years, 123 00:07:32,080 --> 00:07:34,600 Speaker 1: I bet it's even higher than that now. But the 124 00:07:34,640 --> 00:07:38,000 Speaker 1: idea being that after the reason why it would record 125 00:07:38,120 --> 00:07:40,080 Speaker 1: over after the last couple of hours is the only 126 00:07:40,120 --> 00:07:42,120 Speaker 1: reason you would need to review this in the first places. 127 00:07:42,120 --> 00:07:44,440 Speaker 1: If there was a catastrophic accident, and the chances are 128 00:07:45,040 --> 00:07:47,880 Speaker 1: that anything that would really indicate a problem would have 129 00:07:47,920 --> 00:07:51,440 Speaker 1: occurred half an hour or closer to the actual event. 130 00:07:51,560 --> 00:07:54,320 Speaker 1: You're not you know, it's not gonna you know, any 131 00:07:54,360 --> 00:07:58,360 Speaker 1: problem that's that serious, that's detected earlier would probably result 132 00:07:58,360 --> 00:08:01,440 Speaker 1: in an emergency landing, unless, of course you were maybe 133 00:08:01,520 --> 00:08:04,880 Speaker 1: over a huge body of water and couldn't do that right, Right, 134 00:08:05,320 --> 00:08:09,360 Speaker 1: So that's the reason for the you know, that's why 135 00:08:09,640 --> 00:08:11,280 Speaker 1: you're not too concerned over the fact that's going to 136 00:08:11,360 --> 00:08:17,280 Speaker 1: record over the previous you know recording, UM, the flight 137 00:08:17,360 --> 00:08:19,440 Speaker 1: data recorder. That's very important as well, because it will 138 00:08:19,480 --> 00:08:23,720 Speaker 1: record all the conditions that were uh that we're leading 139 00:08:23,800 --> 00:08:26,600 Speaker 1: up to the incident, and then of course everything thereafter, 140 00:08:27,240 --> 00:08:30,240 Speaker 1: and that gives investigators a chance to really determine what 141 00:08:30,280 --> 00:08:32,400 Speaker 1: it was that caused the problem in the first place. 142 00:08:33,080 --> 00:08:35,480 Speaker 1: And uh, I mean that's important. You know, if it's 143 00:08:35,480 --> 00:08:38,520 Speaker 1: a manufacturing error, then obviously that's something you have to address, 144 00:08:38,559 --> 00:08:40,640 Speaker 1: because what if that affects everything else in the fleet 145 00:08:41,280 --> 00:08:46,200 Speaker 1: of planes or everything that's you know, of that same designation, right, 146 00:08:46,240 --> 00:08:48,880 Speaker 1: I mean, this is um it's gonna track all kinds 147 00:08:48,920 --> 00:08:53,760 Speaker 1: of information about the aircraft. Uh, you know, including stuff 148 00:08:53,760 --> 00:08:56,480 Speaker 1: that I said before, all about the flaps, the positions 149 00:08:56,520 --> 00:08:59,760 Speaker 1: of the flaps and and things like that, air speed. Um, 150 00:08:59,800 --> 00:09:02,560 Speaker 1: and based on the conditions and uh, you know, maybe 151 00:09:02,559 --> 00:09:05,760 Speaker 1: the weather conditions in the area and anything that the 152 00:09:05,800 --> 00:09:09,200 Speaker 1: pilot might have said. They can sort of piece together 153 00:09:09,400 --> 00:09:11,520 Speaker 1: what may have happened in the event of an accident 154 00:09:11,800 --> 00:09:13,959 Speaker 1: right now, and they're there are plenty of transcripts out 155 00:09:13,960 --> 00:09:17,640 Speaker 1: there from that. We're taken from black box recordings, and uh, 156 00:09:17,679 --> 00:09:19,640 Speaker 1: I tried reading a few of them, and after a couple, 157 00:09:19,679 --> 00:09:22,559 Speaker 1: I'm like, I can't read any more of these. It's 158 00:09:22,559 --> 00:09:25,720 Speaker 1: a little too intense for me. Um. You might wonder 159 00:09:25,720 --> 00:09:29,840 Speaker 1: water these these black boxes made of these black boxes 160 00:09:29,840 --> 00:09:33,520 Speaker 1: that are neither black nor boxes. Um. Well, you've got 161 00:09:33,559 --> 00:09:38,480 Speaker 1: an aluminum housing that surrounds the sensitive equipment. Then you 162 00:09:38,559 --> 00:09:41,080 Speaker 1: have you have some insulation that goes around that because 163 00:09:41,080 --> 00:09:43,560 Speaker 1: of course, if there is a fire, right and jet 164 00:09:43,600 --> 00:09:46,360 Speaker 1: fuel burns pretty hot, yes, so you have to have 165 00:09:46,440 --> 00:09:50,160 Speaker 1: something that can withstand intense heat and protect the electronics 166 00:09:50,160 --> 00:09:53,320 Speaker 1: insided so that people when they recover the electronics can 167 00:09:53,400 --> 00:09:56,200 Speaker 1: figure out what happened. Um. And then around that you 168 00:09:56,280 --> 00:10:01,000 Speaker 1: have a stainless steel shell. Wow. Yeah, so I mean, 169 00:10:01,600 --> 00:10:04,520 Speaker 1: and people often make that like that. I've heard comedians 170 00:10:04,559 --> 00:10:08,440 Speaker 1: make the joke of, you know, when there's an airplane crash, 171 00:10:08,559 --> 00:10:10,679 Speaker 1: they find the black box and it's fine, Why don't 172 00:10:10,720 --> 00:10:14,679 Speaker 1: they make the whole airplane out of that hauh? Because 173 00:10:14,720 --> 00:10:19,760 Speaker 1: it be way too heavy, that's why. But that's not funny. 174 00:10:19,960 --> 00:10:21,840 Speaker 1: I guess. I guess if you stand up and you 175 00:10:21,960 --> 00:10:24,640 Speaker 1: and you talk back to a comedian who's doing observational humor, 176 00:10:24,679 --> 00:10:27,200 Speaker 1: and you explain in logical terms why the joke would 177 00:10:27,240 --> 00:10:29,839 Speaker 1: not work, that makes it less funny. I suppose I 178 00:10:29,880 --> 00:10:32,160 Speaker 1: would imagine that that would not endear you to your 179 00:10:32,160 --> 00:10:36,160 Speaker 1: fellow you know, crowd members. Yeah, that that explains why 180 00:10:36,200 --> 00:10:40,680 Speaker 1: I'm no longer allowed in the chuckle hut. So yeah, 181 00:10:41,160 --> 00:10:42,600 Speaker 1: do you like that? I just came up with it, 182 00:10:42,679 --> 00:10:46,600 Speaker 1: all right. So another thing that these uh, these black 183 00:10:46,600 --> 00:10:52,640 Speaker 1: boxes have usually is an underwater locator beacon. Oh yeah, yeah, 184 00:10:52,679 --> 00:10:54,840 Speaker 1: that would be very useful well, of course, Yeah, if 185 00:10:54,840 --> 00:10:57,320 Speaker 1: you if you do happen to have an emergency water 186 00:10:57,400 --> 00:11:00,120 Speaker 1: landing or a crash, you would need to have some 187 00:11:00,200 --> 00:11:03,920 Speaker 1: way of being able to find this this device underwater 188 00:11:04,800 --> 00:11:07,720 Speaker 1: and the way these systems work is they have a 189 00:11:07,760 --> 00:11:12,920 Speaker 1: sensor that will detect if the black box goes underwater, 190 00:11:13,360 --> 00:11:18,080 Speaker 1: and then it activates a a subsonic signal. Actually I'm sorry, 191 00:11:18,120 --> 00:11:20,199 Speaker 1: an ultrasonic signal, so I should go the other way, 192 00:11:20,280 --> 00:11:24,559 Speaker 1: not subsonicum, ultrasonic signal, And so you can't hear it, 193 00:11:24,720 --> 00:11:28,320 Speaker 1: but it can be detected by UH wall detection equipment, 194 00:11:28,720 --> 00:11:31,880 Speaker 1: so people searching around the area using the right equipment 195 00:11:31,920 --> 00:11:35,120 Speaker 1: can locate it very quickly. Right, so it's a pitch 196 00:11:35,200 --> 00:11:37,719 Speaker 1: so high that only underwater dogs can hear it. Right, 197 00:11:38,480 --> 00:11:41,360 Speaker 1: it might affect the behavior of dolphins in the area, 198 00:11:41,480 --> 00:11:45,880 Speaker 1: but other than that, right, And even despite that, of course, um, 199 00:11:45,920 --> 00:11:49,480 Speaker 1: they can't always find some of the the black boxes. 200 00:11:49,520 --> 00:11:52,079 Speaker 1: I mean that happened in the case of that that 201 00:11:52,160 --> 00:11:58,079 Speaker 1: crash in the ocean earlier summer or two thousand nine. Um, 202 00:11:58,120 --> 00:12:00,400 Speaker 1: as far as I know, last i'd see they had 203 00:12:00,520 --> 00:12:02,520 Speaker 1: they'd given up looking for it because they were unable 204 00:12:02,559 --> 00:12:04,560 Speaker 1: to find that signal. Yeah, well, I mean there are 205 00:12:04,640 --> 00:12:07,160 Speaker 1: many things that could affect that. I mean you're talking about, 206 00:12:07,320 --> 00:12:10,480 Speaker 1: like the wreckage of a crash can spread over a 207 00:12:10,600 --> 00:12:12,800 Speaker 1: very wide area, so that makes it difficult. Then of 208 00:12:12,840 --> 00:12:15,800 Speaker 1: course you have things like currents and the depth of 209 00:12:15,800 --> 00:12:19,920 Speaker 1: the water exactly. Um was not exactly known for not 210 00:12:20,080 --> 00:12:24,880 Speaker 1: distorting audio, right, Yeah, so it might depending on many 211 00:12:24,920 --> 00:12:28,040 Speaker 1: different uh factors, you may or may not be able 212 00:12:28,040 --> 00:12:30,880 Speaker 1: to find that very quickly. But that's the whole purpose 213 00:12:30,880 --> 00:12:33,000 Speaker 1: of it is to to try and facilitate that, make 214 00:12:33,040 --> 00:12:35,560 Speaker 1: it a little easier, so that the answers can can 215 00:12:35,600 --> 00:12:38,680 Speaker 1: be found too. I mean, anytime there's a crash, there's 216 00:12:38,679 --> 00:12:41,360 Speaker 1: gonna be lots of questions about exactly what happened. You know, 217 00:12:41,480 --> 00:12:44,000 Speaker 1: was it human error, was it mechanical error, was it 218 00:12:44,160 --> 00:12:46,680 Speaker 1: you know, unexpected turbulence, all that kind of stuff everyone 219 00:12:46,720 --> 00:12:49,679 Speaker 1: wants to know. I mean, you know, it's a very 220 00:12:49,679 --> 00:12:54,640 Speaker 1: traumatic experience. Um, moving on to unless you have anything 221 00:12:54,679 --> 00:12:56,120 Speaker 1: else about black boxes. I was going to move on 222 00:12:56,120 --> 00:12:58,000 Speaker 1: to a different technology now. I was going to say, 223 00:12:58,040 --> 00:13:00,280 Speaker 1: you know, that's you know we've been talking about that's 224 00:13:00,360 --> 00:13:02,720 Speaker 1: kind of a somber one way. You always have something 225 00:13:02,720 --> 00:13:06,160 Speaker 1: else that's not not so somber. Um, this is this 226 00:13:06,200 --> 00:13:09,640 Speaker 1: isn't necessarily upbeaten chipper. It's just a neat technology. I 227 00:13:09,679 --> 00:13:14,960 Speaker 1: was gonna talk about transponders. So transponder is a well 228 00:13:15,000 --> 00:13:17,520 Speaker 1: the word transponder. It's kind of a combination of the 229 00:13:17,559 --> 00:13:23,599 Speaker 1: words transmitter and responder. That's a transponder. The idea is 230 00:13:23,640 --> 00:13:26,000 Speaker 1: that it's a device that when you send a signal, 231 00:13:26,160 --> 00:13:30,000 Speaker 1: it automatically sends a signal back. And it was very 232 00:13:30,080 --> 00:13:33,679 Speaker 1: useful during World War Two because what they used. The 233 00:13:34,240 --> 00:13:36,880 Speaker 1: way the military used transponders was it was a way 234 00:13:36,880 --> 00:13:41,560 Speaker 1: to identify planes as being allied planes. Clearly, I mean, 235 00:13:41,559 --> 00:13:45,559 Speaker 1: you wouldn't want to fire upon an allied UH airplane. 236 00:13:45,600 --> 00:13:49,240 Speaker 1: That's a typically considered a bad tactic in warfare, as 237 00:13:49,240 --> 00:13:52,360 Speaker 1: I understand it, So you would not want to fire 238 00:13:52,400 --> 00:13:54,559 Speaker 1: upon one of your own allies that you've got this transponder. 239 00:13:54,600 --> 00:13:56,160 Speaker 1: You send a signal out, you get a signal back, 240 00:13:56,200 --> 00:13:59,520 Speaker 1: you see that this is one of the signals that 241 00:14:00,160 --> 00:14:04,520 Speaker 1: UM signifies a friend, you don't fire upon them. Now 242 00:14:04,520 --> 00:14:08,400 Speaker 1: in commercial jets, it's more of a way to identify 243 00:14:08,520 --> 00:14:11,520 Speaker 1: the plane and make sure that you're that they're on 244 00:14:11,559 --> 00:14:14,440 Speaker 1: the right track, they're on the right flight path, UM 245 00:14:14,720 --> 00:14:18,080 Speaker 1: and UH so it's very useful for air traffic control 246 00:14:19,200 --> 00:14:21,440 Speaker 1: and UM. I used to have to write a lot 247 00:14:21,640 --> 00:14:24,960 Speaker 1: about transponders. One of my first jobs out of college 248 00:14:25,600 --> 00:14:29,440 Speaker 1: was I was working for a particular airline which I 249 00:14:29,480 --> 00:14:34,400 Speaker 1: will not name. But um, my job was to take 250 00:14:34,560 --> 00:14:39,280 Speaker 1: really old sound files, uh that were descriptions of the 251 00:14:39,360 --> 00:14:44,560 Speaker 1: various systems aboard their airplanes and transcribe them because they 252 00:14:44,640 --> 00:14:49,000 Speaker 1: lost the hard copy scripts. So I got to listen 253 00:14:49,160 --> 00:14:53,120 Speaker 1: all day two sound files about things like the seven 254 00:14:53,240 --> 00:14:57,200 Speaker 1: forty seven and and write down everything about all their 255 00:14:57,240 --> 00:15:01,880 Speaker 1: various systems. Yeah. That was my job for about well 256 00:15:01,920 --> 00:15:06,160 Speaker 1: a couple of months. Really that long. Yeah, I'm impressed 257 00:15:06,160 --> 00:15:07,760 Speaker 1: as you made it that long. Well, it was a 258 00:15:07,880 --> 00:15:09,840 Speaker 1: temp job in the first place. It wasn't it wasn't 259 00:15:09,920 --> 00:15:15,080 Speaker 1: a permanent assignment. Yeah, no, I know, I know more 260 00:15:15,120 --> 00:15:20,920 Speaker 1: about the m D A eight than I cared to remember. Well, um, 261 00:15:20,960 --> 00:15:24,440 Speaker 1: you know, actually transponders are very important because they lead 262 00:15:24,480 --> 00:15:28,000 Speaker 1: to some non airplane airplane tech too. Yeah, because not 263 00:15:28,160 --> 00:15:31,520 Speaker 1: just using aircraft. Well that's that's not exactly what I meant, 264 00:15:31,880 --> 00:15:34,600 Speaker 1: because part of um, the tech used in flying a 265 00:15:34,680 --> 00:15:37,520 Speaker 1: plane is based on the ground. Well that's true too, 266 00:15:37,760 --> 00:15:41,400 Speaker 1: because the transponder is used by air traffic control, very 267 00:15:41,520 --> 00:15:45,760 Speaker 1: human piece of airplane tech to keep an eye on 268 00:15:45,840 --> 00:15:49,000 Speaker 1: everything and there. Um there's we have an article on 269 00:15:49,240 --> 00:15:53,400 Speaker 1: um that actually sort of you know, went through and 270 00:15:53,920 --> 00:15:57,320 Speaker 1: made some minor changes on not too long ago about uh, 271 00:15:57,560 --> 00:15:59,800 Speaker 1: the how the f a A A works. It's kind of 272 00:16:00,080 --> 00:16:04,520 Speaker 1: thing because you realize that the FAA is tracking those 273 00:16:04,520 --> 00:16:08,920 Speaker 1: planes pretty much everywhere. They are using that transponder signal, um, 274 00:16:09,000 --> 00:16:12,960 Speaker 1: using the ground control equipment and basically they subdivide the 275 00:16:12,960 --> 00:16:17,240 Speaker 1: country into different sections and with each individual. I mean, 276 00:16:17,440 --> 00:16:20,840 Speaker 1: you know that transponder code from that particular aircraft is 277 00:16:20,960 --> 00:16:24,040 Speaker 1: unique to that plane. So, um, you know that's a 278 00:16:24,160 --> 00:16:27,080 Speaker 1: very important part at tech because at any given moment, 279 00:16:27,120 --> 00:16:31,840 Speaker 1: they're they're aware of where that is. That's true, That's true. 280 00:16:32,120 --> 00:16:34,920 Speaker 1: And of course we now also have the um the 281 00:16:34,960 --> 00:16:40,080 Speaker 1: wonderful technology of GPS, and many planes have a GPS 282 00:16:40,160 --> 00:16:43,000 Speaker 1: receiver that so that the pilot can see very quickly 283 00:16:43,920 --> 00:16:48,440 Speaker 1: exactly where the plane is. And um that's often a 284 00:16:48,560 --> 00:16:52,960 Speaker 1: useful thing, especially in really bad flying conditions. Uh, I 285 00:16:53,000 --> 00:16:55,600 Speaker 1: was gonna talk a little bit. And and the GPS 286 00:16:55,640 --> 00:16:57,160 Speaker 1: also comes in handy if you have to be sitting 287 00:16:57,160 --> 00:16:58,800 Speaker 1: on one of those planes that has the monitor in 288 00:16:58,800 --> 00:17:00,240 Speaker 1: the back of the seat in front of you and 289 00:17:00,280 --> 00:17:03,800 Speaker 1: you get want a track where you're plane is. Yeah, 290 00:17:03,840 --> 00:17:06,760 Speaker 1: it gives you the flight track information and you're like, wow, 291 00:17:07,640 --> 00:17:12,159 Speaker 1: we're directly over Tucson right now. Um. But I was 292 00:17:12,200 --> 00:17:14,959 Speaker 1: also going to mention there's some other tech on on 293 00:17:15,040 --> 00:17:17,679 Speaker 1: planes that it's a little more recent that. Uh. I 294 00:17:17,680 --> 00:17:20,280 Speaker 1: thought i'd chat about the WiFi that you can get 295 00:17:20,320 --> 00:17:23,960 Speaker 1: on some planes. Now, okay, I have an older piece 296 00:17:24,000 --> 00:17:26,760 Speaker 1: of tech too, So do you want to do that ahead? No? No, no, 297 00:17:26,800 --> 00:17:30,320 Speaker 1: it's okay. If we're going chronologically, then I should skip 298 00:17:30,359 --> 00:17:34,200 Speaker 1: back real quick. Shoot for it. One, two, three, shoot 299 00:17:34,280 --> 00:17:38,640 Speaker 1: all right, all right, Chris, one, go ahead, Um yeah, 300 00:17:38,680 --> 00:17:41,800 Speaker 1: I l S. Oh all right. Um. The I l 301 00:17:41,920 --> 00:17:46,040 Speaker 1: S system is basically tells a pilot where he or 302 00:17:46,119 --> 00:17:49,879 Speaker 1: she is with regard to a runway. Um. It actually 303 00:17:49,920 --> 00:17:54,440 Speaker 1: uses combination of radio signals based around, um, the runway 304 00:17:54,480 --> 00:17:58,720 Speaker 1: itself and uh so maybe the runway is obscured by clouds. 305 00:17:59,320 --> 00:18:02,760 Speaker 1: Um it will you know use sort of. It uses 306 00:18:02,800 --> 00:18:06,560 Speaker 1: a combination of altitude, well, the glide path and then 307 00:18:07,200 --> 00:18:11,200 Speaker 1: also the uh you know, it's the excuse me, Instrument 308 00:18:11,280 --> 00:18:13,199 Speaker 1: Landing system is what I l S is short for. 309 00:18:13,359 --> 00:18:15,880 Speaker 1: So it basically is giving them a combination of while 310 00:18:15,960 --> 00:18:19,360 Speaker 1: you are right here with regard to the runway. Uh, 311 00:18:19,400 --> 00:18:21,320 Speaker 1: you should you know, turn this way a little bit 312 00:18:21,359 --> 00:18:23,560 Speaker 1: and you'll be lined up with the runway. So even 313 00:18:23,640 --> 00:18:26,320 Speaker 1: if he or she can't see it, um, they know 314 00:18:26,400 --> 00:18:29,479 Speaker 1: exactly where it is based on the signals generated from 315 00:18:29,520 --> 00:18:33,400 Speaker 1: the ground, and you know, they coordinate that with where 316 00:18:33,440 --> 00:18:35,399 Speaker 1: the plane is. So that's a very useful piece of 317 00:18:35,480 --> 00:18:38,640 Speaker 1: definitely technology because if you've ever wondered when you're coming 318 00:18:38,680 --> 00:18:41,040 Speaker 1: into an airport and it's cloudy out and they make 319 00:18:41,040 --> 00:18:43,840 Speaker 1: a perfect landing, that's how they're doing it. They're relying 320 00:18:43,880 --> 00:18:47,560 Speaker 1: on that instrumentation to help them help them find where 321 00:18:47,600 --> 00:18:51,280 Speaker 1: they are. Also, the orientation really important. Whenever Johnny unplugs 322 00:18:51,320 --> 00:18:55,000 Speaker 1: the lights on the runway, that happens in so few 323 00:18:55,040 --> 00:19:02,800 Speaker 1: circumstances that that's problem. Surely you can't be serious, um, 324 00:19:02,840 --> 00:19:05,959 Speaker 1: all right, so now we'll go on to the WiFi. Alright, 325 00:19:07,240 --> 00:19:11,640 Speaker 1: the WiFi, No Johnny's on the ground. So yeah, WiFi 326 00:19:11,680 --> 00:19:15,320 Speaker 1: on planes is fairly recent. Um. It's something that had 327 00:19:15,359 --> 00:19:18,359 Speaker 1: been discussed, uh well for a few years now, and 328 00:19:19,080 --> 00:19:21,640 Speaker 1: a couple of companies have been doing it for since 329 00:19:21,680 --> 00:19:24,439 Speaker 1: about I guess around two thousand and six, but in 330 00:19:24,480 --> 00:19:27,080 Speaker 1: the United States it's a little more recent than that. 331 00:19:27,600 --> 00:19:33,480 Speaker 1: And um, it's a it's a pretty simple system. They 332 00:19:33,359 --> 00:19:36,600 Speaker 1: there's some technology, there's equipment that's put aboard the plane 333 00:19:36,600 --> 00:19:38,880 Speaker 1: that turns it turns it into a hot spot essentially, 334 00:19:39,720 --> 00:19:45,199 Speaker 1: and your laptop or other device can connect wirelessly to 335 00:19:45,359 --> 00:19:51,199 Speaker 1: this using typical WiFi technology, and then the hardware on 336 00:19:51,240 --> 00:19:54,600 Speaker 1: the plane actually sends that signal down to the ground 337 00:19:54,760 --> 00:19:58,359 Speaker 1: to towers on the ground and communicates that way. And 338 00:19:58,400 --> 00:20:01,920 Speaker 1: that's how you are getting acces us too, uh, the Internet. 339 00:20:02,200 --> 00:20:04,560 Speaker 1: So it's not like, you know, you're you're not tapping 340 00:20:04,560 --> 00:20:09,000 Speaker 1: into this magical Internet that's all around you in the air. Um. Really, 341 00:20:09,480 --> 00:20:11,119 Speaker 1: the reason why you're able to do it is because 342 00:20:11,160 --> 00:20:15,320 Speaker 1: the plane has a very specific kind of transceiver. Really, 343 00:20:15,920 --> 00:20:20,160 Speaker 1: it's a very very long Ethernet cable. Yes, right, there's 344 00:20:20,320 --> 00:20:23,600 Speaker 1: there's some poor schlubs job to just keep unwinding that 345 00:20:23,680 --> 00:20:27,359 Speaker 1: cord and then another poor poor person's job to wind 346 00:20:27,359 --> 00:20:32,440 Speaker 1: it all. No, it's not wired. Man, Talk about the 347 00:20:32,520 --> 00:20:36,560 Speaker 1: letters we would get from that one? Yeah? Um, was 348 00:20:36,560 --> 00:20:38,560 Speaker 1: that all with WiFi? Yeah? That was all I had 349 00:20:38,600 --> 00:20:40,680 Speaker 1: for a WiFi. It was just really it's just interesting 350 00:20:40,720 --> 00:20:43,560 Speaker 1: to me that it's you know, again, you're turning the 351 00:20:43,560 --> 00:20:46,119 Speaker 1: plane itself into a hot spot, and depending on what 352 00:20:46,200 --> 00:20:49,919 Speaker 1: airline you're on, you'll see that they have different um uh, 353 00:20:50,280 --> 00:20:56,000 Speaker 1: different pricing plans for it. Um. Some some people found difficulty, um. People, 354 00:20:56,119 --> 00:21:01,880 Speaker 1: some companies found difficulty implementing this and making it uh profitable. UM. 355 00:21:01,920 --> 00:21:04,640 Speaker 1: I think Boeing did it briefly and then jumped out 356 00:21:04,640 --> 00:21:08,840 Speaker 1: of it in the connection. Yeah yeah, I think. Weren't 357 00:21:08,840 --> 00:21:11,040 Speaker 1: they charging like thirty bucks a flight or something like that. 358 00:21:11,240 --> 00:21:12,639 Speaker 1: I don't know about the price point, but I do 359 00:21:12,680 --> 00:21:15,320 Speaker 1: know that they've done They've washed their hands and yeah, yeah, 360 00:21:15,359 --> 00:21:17,880 Speaker 1: what happened was, as I recall, the way it worked 361 00:21:17,920 --> 00:21:20,879 Speaker 1: was they were charging thirty bucks for per flight. No. 362 00:21:21,119 --> 00:21:24,119 Speaker 1: I don't know that necessarily um scale depending on the 363 00:21:24,200 --> 00:21:27,879 Speaker 1: length of the flight. But because most people weren't willing 364 00:21:27,920 --> 00:21:30,000 Speaker 1: to pay about as much as it costs to have 365 00:21:30,119 --> 00:21:34,320 Speaker 1: WiFi for a month at your house for a single flight, um, 366 00:21:34,359 --> 00:21:37,280 Speaker 1: it ended up not making Bowing very much money and 367 00:21:37,359 --> 00:21:40,320 Speaker 1: they abandoned the project. But other you know, like actual 368 00:21:40,359 --> 00:21:45,960 Speaker 1: airlines have have implemented this on their own and um, 369 00:21:46,200 --> 00:21:48,159 Speaker 1: there are a couple of companies that partner with to 370 00:21:48,240 --> 00:21:51,600 Speaker 1: do that. Yeah. Um, and they give you broadband speeds 371 00:21:51,600 --> 00:21:55,399 Speaker 1: of slowish DSL, So I mean it's it's fast, but 372 00:21:55,440 --> 00:21:58,240 Speaker 1: not really really fast. Yeah. Yeah, most people I think 373 00:21:58,240 --> 00:22:00,200 Speaker 1: will be using it to do things like checking l 374 00:22:00,320 --> 00:22:01,800 Speaker 1: I mean you might have a few folks who are 375 00:22:02,080 --> 00:22:04,399 Speaker 1: you know, wanting to use it to to use Hulu 376 00:22:04,480 --> 00:22:06,919 Speaker 1: so they can avoid having to watch whatever the movie 377 00:22:07,000 --> 00:22:09,600 Speaker 1: is on board the plane. Yeah, there's only so many 378 00:22:09,640 --> 00:22:13,919 Speaker 1: times you can watch Uncle Buck, by the way, is 379 00:22:13,960 --> 00:22:16,240 Speaker 1: the number of times that would be a good segue 380 00:22:16,280 --> 00:22:20,800 Speaker 1: into a satellite TV though? Um? Now, you know a 381 00:22:20,840 --> 00:22:25,160 Speaker 1: lot of era carriers now offer satellite radio and satellite TV. 382 00:22:25,880 --> 00:22:28,919 Speaker 1: Um and um, they're the signals are a little bit different. 383 00:22:28,920 --> 00:22:32,760 Speaker 1: Satellite radio is not nearly as directional. Uh. So you know, 384 00:22:33,200 --> 00:22:36,840 Speaker 1: really it doesn't matter. The antenna position doesn't matter nearly 385 00:22:36,840 --> 00:22:38,919 Speaker 1: as much as it does for a satellite TV. If 386 00:22:38,960 --> 00:22:41,800 Speaker 1: you're a person that owns a satellite dish, uh, and 387 00:22:41,840 --> 00:22:44,040 Speaker 1: it's in your yard and you know, the neighbor's kid 388 00:22:44,119 --> 00:22:46,040 Speaker 1: kicked a soccer ball into it, and it looks like 389 00:22:46,119 --> 00:22:48,080 Speaker 1: it's position right, but it through your TV signal off. 390 00:22:48,119 --> 00:22:52,080 Speaker 1: You know that satellite TV signals are a bit more directional. Well, 391 00:22:52,280 --> 00:22:55,719 Speaker 1: you say, is there a little you know? Uh? William 392 00:22:55,800 --> 00:22:59,960 Speaker 1: Shatner type guy out on the wing repositioning that side 393 00:23:00,080 --> 00:23:04,720 Speaker 1: light dish. William Shatner was inside the plane. Okay, that's 394 00:23:04,720 --> 00:23:11,320 Speaker 1: not sorry, shall I shall I restate there's not a 395 00:23:11,359 --> 00:23:14,720 Speaker 1: little uh, you know, gremlin like William Shatner saw through 396 00:23:14,760 --> 00:23:18,240 Speaker 1: the window of the plane. UM out there repositioning the 397 00:23:18,280 --> 00:23:21,919 Speaker 1: satellite dish and actually uses for satellite TV on a plane. 398 00:23:22,280 --> 00:23:25,600 Speaker 1: You actually have a specialized antenna that tracks the position 399 00:23:25,640 --> 00:23:28,199 Speaker 1: of the satellite and automatically corrects itself so that it 400 00:23:28,240 --> 00:23:32,800 Speaker 1: can maintain its line of sight to the satellite UM 401 00:23:32,880 --> 00:23:36,639 Speaker 1: and continue to receive satellite TV signals. That's pretty it's 402 00:23:36,720 --> 00:23:40,800 Speaker 1: kind of a you know, considering the cost of a 403 00:23:40,840 --> 00:23:42,320 Speaker 1: regular dish they would put it on the side of 404 00:23:42,320 --> 00:23:45,040 Speaker 1: your house. It's considerably more expensive than that. UM. I 405 00:23:45,040 --> 00:23:46,359 Speaker 1: don't know how much they are now. They used to 406 00:23:46,440 --> 00:23:48,800 Speaker 1: range in thousands of dollars, of course, you know, compared 407 00:23:48,800 --> 00:23:52,520 Speaker 1: to the cost of an entire plane. That's nothing, um, 408 00:23:52,680 --> 00:23:56,760 Speaker 1: not literally peanuts. Those are actually cheaper well you know, 409 00:23:56,840 --> 00:24:01,600 Speaker 1: and may cause allergies, um, making tain nuts right, UM. 410 00:24:01,640 --> 00:24:03,959 Speaker 1: But you know that's kind of an interesting technology too, 411 00:24:04,000 --> 00:24:06,399 Speaker 1: because it has to it can't just it's not like 412 00:24:06,440 --> 00:24:08,960 Speaker 1: a you know, a terrestrial antenna where just you know, 413 00:24:09,000 --> 00:24:11,320 Speaker 1: stick a thing on top of the car and it goes. 414 00:24:11,440 --> 00:24:15,400 Speaker 1: You actually have to pay attention to where the satellite is. Um, 415 00:24:15,440 --> 00:24:19,119 Speaker 1: that's kind of a neat little gimmick. Cool, Well, do 416 00:24:19,160 --> 00:24:21,399 Speaker 1: you have anything else anymore airplane tech you want to 417 00:24:21,440 --> 00:24:24,560 Speaker 1: talk about? You know? Not? Really? All right? Well, I'm 418 00:24:24,640 --> 00:24:28,440 Speaker 1: I'm actually I'm all tapped out. So, like we said, 419 00:24:28,480 --> 00:24:32,240 Speaker 1: this is just another kind of overview because there's plenty 420 00:24:32,240 --> 00:24:34,680 Speaker 1: more that we could talk about, but not not more 421 00:24:34,720 --> 00:24:36,639 Speaker 1: that we're prepared to talk about. It's sort of a 422 00:24:36,720 --> 00:24:39,600 Speaker 1: high level maybe thirty five thousand feet, Yeah, it's right 423 00:24:39,640 --> 00:24:43,399 Speaker 1: around there. Turbulence. We'll we'll, we'll descend to maybe, you know, 424 00:24:43,960 --> 00:24:48,600 Speaker 1: eight thousand if that happens. This has been a turbulent podcast. 425 00:24:48,640 --> 00:24:50,560 Speaker 1: So with that, let's let's just go ahead and move 426 00:24:50,560 --> 00:24:57,440 Speaker 1: on to a listener mail. And this listener mail comes 427 00:24:57,480 --> 00:25:00,440 Speaker 1: from Matt and Uh. I cut out a lot of 428 00:25:00,480 --> 00:25:02,439 Speaker 1: Matt's email, but I've got the crux of it here, 429 00:25:02,480 --> 00:25:05,000 Speaker 1: and Matt says, Hey, Chris and Jonathan, I was wondering 430 00:25:05,040 --> 00:25:08,640 Speaker 1: what the differences between virus protection and internet security. Do 431 00:25:08,680 --> 00:25:11,600 Speaker 1: I need internet security or just anti virus what makes 432 00:25:11,640 --> 00:25:15,480 Speaker 1: internet security costs so much more. Some people also say 433 00:25:15,480 --> 00:25:18,360 Speaker 1: that I should have a program specifically for spyware removal 434 00:25:18,480 --> 00:25:23,520 Speaker 1: along with my virus protection or whatever. Is this true, sincerely, Matt. Now, 435 00:25:23,600 --> 00:25:26,359 Speaker 1: what Matt was referring to were some specific products that 436 00:25:26,359 --> 00:25:29,240 Speaker 1: are on the market for anti virus and internet security. 437 00:25:29,640 --> 00:25:33,080 Speaker 1: Um So, Matt, here's kind of what all that means. Now. 438 00:25:33,080 --> 00:25:36,679 Speaker 1: An anti virus program in general, specifically is designed to 439 00:25:36,920 --> 00:25:40,600 Speaker 1: search out any signs of viruses on your computer and 440 00:25:40,680 --> 00:25:44,920 Speaker 1: often other kinds of malware to trojan's that kind of thing. Yeah, 441 00:25:44,960 --> 00:25:48,679 Speaker 1: pretty much, a malware detection program is what that is. 442 00:25:49,400 --> 00:25:52,280 Speaker 1: And most anti virus, if it's if it just says 443 00:25:52,280 --> 00:25:55,800 Speaker 1: anti virus, that's really what it does. It goes after malware, uh, 444 00:25:55,840 --> 00:26:00,760 Speaker 1: anti spyware that's looking specifically for any sort of tracking 445 00:26:00,840 --> 00:26:03,840 Speaker 1: software that's being put on your computer. Basically anything that's 446 00:26:03,840 --> 00:26:08,440 Speaker 1: gonna phone home with information about you anywhere from your 447 00:26:09,119 --> 00:26:12,720 Speaker 1: passwords and uh, you know, personal information like that, to 448 00:26:13,040 --> 00:26:16,080 Speaker 1: you know, marketing type spyware where it's just saying, yeah, 449 00:26:16,119 --> 00:26:18,600 Speaker 1: you know, he's visiting two and three websites and these 450 00:26:18,640 --> 00:26:21,639 Speaker 1: are what they are, right, he's really interested in shoes, 451 00:26:21,680 --> 00:26:24,240 Speaker 1: so you should send him targeted marketing. Yeah, that kind 452 00:26:24,240 --> 00:26:26,480 Speaker 1: of stuff. I mean, that's not nearly as annoying as 453 00:26:26,880 --> 00:26:29,640 Speaker 1: uh some of the other stuff, but it is annoying, right, Yeah, 454 00:26:29,640 --> 00:26:32,719 Speaker 1: it's it's pretty irritating. And so again, if it just 455 00:26:32,720 --> 00:26:36,080 Speaker 1: says anti spyware, that's pretty much all it's looking for. UH. 456 00:26:36,119 --> 00:26:39,560 Speaker 1: Internet security packages tend to have all of that wrapped 457 00:26:39,640 --> 00:26:43,200 Speaker 1: up into one UM product and often have a firewall 458 00:26:43,240 --> 00:26:45,399 Speaker 1: and in their firewall as well, so you'll have a 459 00:26:45,480 --> 00:26:50,760 Speaker 1: firewall which can protect against intrusions from from outside your 460 00:26:50,880 --> 00:26:54,240 Speaker 1: your network. You'll have the antivirus who have the anti spyware. 461 00:26:55,040 --> 00:26:57,760 Speaker 1: So that's why it's more expensive. It's because it's actually 462 00:26:57,800 --> 00:27:01,159 Speaker 1: packaging together lots of stuff. Now, there are lots of 463 00:27:01,359 --> 00:27:04,600 Speaker 1: UM lots of UH products on the market, some of 464 00:27:04,600 --> 00:27:07,960 Speaker 1: them are actually free. So really what I suggest is 465 00:27:08,280 --> 00:27:11,280 Speaker 1: research these different products, find the one that's right for you. 466 00:27:11,600 --> 00:27:14,280 Speaker 1: We don't really review products, and uh we don't really 467 00:27:14,280 --> 00:27:17,960 Speaker 1: feel feel comfortable making a recommendation UM, especially since we 468 00:27:17,960 --> 00:27:20,680 Speaker 1: don't necessarily know what kind of machine you're running. UH. 469 00:27:20,800 --> 00:27:22,480 Speaker 1: Some of the you've got to also keep in mind 470 00:27:22,480 --> 00:27:26,440 Speaker 1: the anti spyware and anti virus technology while it is scanning. 471 00:27:26,960 --> 00:27:32,120 Speaker 1: They tend to be really um well because they're tracking 472 00:27:32,160 --> 00:27:35,040 Speaker 1: everything that's going on in an attempt to protect you, 473 00:27:35,200 --> 00:27:37,600 Speaker 1: and that can slow your computer down. Yes, exactly. Their 474 00:27:37,640 --> 00:27:40,199 Speaker 1: resource hogs is what they really are. UM. I mean, 475 00:27:40,240 --> 00:27:42,560 Speaker 1: they're very important to have, but they're gonna they're gonna 476 00:27:42,560 --> 00:27:45,480 Speaker 1: slow your computer down while they're running. UM Now, they'll 477 00:27:45,520 --> 00:27:47,919 Speaker 1: just run in order to scan, and once they've scanned, 478 00:27:47,920 --> 00:27:49,320 Speaker 1: you should be all right. Now. A lot of them 479 00:27:49,400 --> 00:27:52,280 Speaker 1: have kind of ongoing software that will continue to monitor 480 00:27:52,680 --> 00:27:55,879 Speaker 1: traffic as you are using your computer. UM, Like it 481 00:27:55,960 --> 00:27:59,280 Speaker 1: might check your email attachments as they're downloaded to your 482 00:27:59,280 --> 00:28:01,879 Speaker 1: computer and going, hey, this one's not good, right, don't 483 00:28:01,920 --> 00:28:06,159 Speaker 1: open that um So, but yeah, just keep in mind it. Well, 484 00:28:06,720 --> 00:28:08,720 Speaker 1: these are very resource heavy. It's not something you don't 485 00:28:08,720 --> 00:28:11,440 Speaker 1: want to constantly be scanning your computer. It's just gonna 486 00:28:11,720 --> 00:28:15,240 Speaker 1: make take forever to do anything else. And uh also 487 00:28:15,320 --> 00:28:17,480 Speaker 1: remember to keep it up to date. No matter what 488 00:28:17,760 --> 00:28:21,359 Speaker 1: software you choose, UM make sure that you are. If 489 00:28:21,400 --> 00:28:24,840 Speaker 1: it has an option to update automatically, I strongly suggest 490 00:28:24,880 --> 00:28:27,400 Speaker 1: you activate it. Yeah, there's a new trend to um 491 00:28:27,480 --> 00:28:33,119 Speaker 1: cloud security where basically the software is there's like a 492 00:28:33,160 --> 00:28:36,560 Speaker 1: little client in your computer, and it's basically constantly updating 493 00:28:36,600 --> 00:28:41,040 Speaker 1: with virus definitions from the cloud. The bulk of the 494 00:28:41,320 --> 00:28:45,160 Speaker 1: software is actually in UM on a computer somewhere else 495 00:28:45,200 --> 00:28:48,480 Speaker 1: on the Internet, which is kind of cool. UM, But 496 00:28:48,560 --> 00:28:50,640 Speaker 1: you know, it's still very new, so I haven't heard 497 00:28:50,640 --> 00:28:53,680 Speaker 1: a whole lot about how they're doing right now. Obviously 498 00:28:53,720 --> 00:28:56,440 Speaker 1: that the reason why updating, of course is so important 499 00:28:56,480 --> 00:28:59,880 Speaker 1: is that people hackers are always working on new kind 500 00:29:00,080 --> 00:29:03,840 Speaker 1: of viruses and malware. Yeah, they take old viruses and 501 00:29:03,920 --> 00:29:06,920 Speaker 1: add a twist to them so that the old virus 502 00:29:06,920 --> 00:29:10,480 Speaker 1: protection software can't recognize them any right, So that's why 503 00:29:10,520 --> 00:29:11,840 Speaker 1: you want to make sure you keep it up to date, 504 00:29:11,840 --> 00:29:14,600 Speaker 1: because as the security firms find out about them, that 505 00:29:14,640 --> 00:29:17,600 Speaker 1: they add definitions to their software so that it can 506 00:29:17,600 --> 00:29:21,240 Speaker 1: be detected and prevented. So hopefully that answers your question. 507 00:29:21,280 --> 00:29:24,240 Speaker 1: Matt Um, Thank you very much for writing in.
