Today I’m going to do a plane crash investigation video Hollywood vs. Reality It’s about a FedEx executive who winds up in an airplane crash and then survives on a deserted island. I’ll explain it all Coming up Hey 74 crew welcome back if you don’t know me, my name is Kelsey I’m a 747 pilot. My channel 74 Gear is all about aviation. So whether you’re a pilot or an aviation enthusiast consider subscribing When I read the comments from Sully and Flight the last two movie reviews that I did it seems like you wanted some more technical aspects of aviation So that’s exactly what I’m gonna do on this Cast Away video I’m gonna get into some more technical aviation aspects of the airplane crash. Let’s get into it Yeah, but where are we Somewhere over the Pacific Ocean. Ah now you pilots. You’re funny Tahiti control FedEx 88 Position Jenna at one five two six. There’s all this turbulence from Santa and those eight tiny reindeer 16:20 Eric is next fuel 95.5 Blaine, if you get through tell them we are deviating south for weather, make another position plot and on your deviation left Tahiti control FedEx 88 position Jenna at 15:26 flight level 350. I got us plotted were 200 miles south of the original course continue planning and check the contingency procedures Tahiti control FedEx 88 Broadcasting in the blind. How do you read? I’ve never been out of comms this long try the higher HF frequency Tahiti control FedEx 88 broadcasting in the blind buckle up Chuck Tahiti control Fedex 88 do you read evening position Jenna at one five two six flight level 3 5 0 expecting Tamara and ones So the first thing I want to mention is just that you notice that in cruise there Tom’s got his shoes off which is totally fine in cruise It’s not a big deal but just something from a safety aspect that I’ve seen a lot of passengers start to do recently is they take off their shoes and Their socks before the plane is even pushed back now if that engine explodes or there’s a situation Where you’re on the taxiway are still on the ground and you need to immediately evacuate that aircraft and you don’t have shoes and socks on and you’re running around there could be glass or Shreds of the engine or who knows what on the ground there? so my advice to you is just don’t take your shoes off until you get up in the cruise and then if you want to Take your shoes and socks off. You can it’s a little bit gross on the floor But that’s your choice now into the film here. You saw that section where Tom is waking up and that netting drops off That’s from the bunk area. So the pilot on some planes have a netting there just so you don’t get bumped out in turbulence We don’t have that on the 74. I guess. I don’t know. They don’t think we’re gonna fall out of bed Our beds are a little lower. I think their beds on this aircraft are stacked So if you’re in the upper bunk, they don’t want you to fall out. I guess kind of like bunk beds So that netting that’s dropping out is just something that is used to keep the pilots into the bed So they don’t fall out if there’s turbulence when you’re crossing an ocean Even now some airlines are requiring pilots to do paper plotting charts And essentially when you get your flight plan from the dispatcher, it’s going to have a route that you’re gonna fly over the ocean From there. You’re gonna draw on a chart exactly each spot you’re gonna be crossing and there’s certain way points or checkpoints that you’re going to be crossing the Chart you’re gonna get is gonna look something like this. This is a mid-pacific chart and on the back here You have a West Pacific plotting chart So essentially once you get your flight plan It’s gonna you’re gonna draw out exactly where you’re gonna be so that line that you saw them draw that highlighted line That’s essentially where they should be on course Once you’re in flight, you’re gonna get the GPS coordinates from the plane and you’re gonna verify it against your plotting chart you’re gonna verify that you are on your scheduled flight plan and the plane is where it’s supposed to be and you are where you

Think you are and you’re gonna verify as you’re crossing the ocean those different white points as you go along Now something to keep in mind is you’re generally not going to end up 200 nautical miles off of your course to give you an idea That would be like the distance from New York to Washington DC You might go 10 or 15 miles off, of course, but you’re generally not gonna go 200 miles off of course to get around a storm ain’t nobody got time for this before you even leave your dispatchers are gonna give you a Dispatch sheet with all the weather on it It’s gonna look like this that weather is going to show your route of flight Which is the red line is that you’re gonna be flying and then it’s going to show you any weather Where the winds are all these different things and you’re gonna get that packet before you even get to the plane now This is an example of a flight that I was doing from Japan to the US so you can see there’s no real inclement weather That’s gonna be on that route of flight If you were gonna have a storm that was gonna be so large that you were gonna have to deviate 200 miles That’s not really likely that’s not gonna be something that’s gonna occur right now with technology the way it is with weather You’re not gonna have a dispatcher. That’s gonna send you there And if you’re looking at the weather before you go, which you should be you’re not gonna go. Yeah, that’s fine I’ll fly to that massive thunderstorm. No big deal. That is not how you’re gonna do it So the relief pilot the pilot jumped out of the bunk says did you try a higher frequency? Try the higher HF frequency? Before you start your ocean crossing you’re gonna get a primary and a secondary Radio frequency to reach them on and those are gonna be high frequency radio Stations that you’re gonna reach them on now, you wouldn’t randomly just go Oh, I’m gonna try a different high frequency or I’m gonna try a different frequency to reach them on That’s just not how it works If you’ve ever flown a plane, you know You can’t just randomly tune up a radio and hope that someone’s gonna be there What you have is that primary and your secondary frequency that you would try to reach the month? There’s a few other ways to communicate with the planes around you but he’s not talking about that He’s talking about high frequencies your primary and secondary Now this movie came out in 2000 more and more what you’re having is something called CP DLC CP DLC is controller pilot data link communication It’s a way for the pilots and air traffic control basically to send text messages back and forth and you’re able to request an altitude Descent or climb or offset for weather or whatever it is you’re able to do that via text message Here’s an example of a CPDLC message that I received on a flight a couple days ago Because I knew I was gonna make this movie so here’s an example of what a CPDLC message would look like air traffic control is writing to us and we’re replying back to Them Roger that’s a way for us to communicate back forth So that way they’re not having to talk on these HF frequencies which as you can hear they’re very Scratchy and they’re not that reliable when you’re over the middle of a Pacific if you have weather things like that for whatever reason You can’t always hear well or at all Depending on where you’re at the CPDLC is a way to circumvent that and it’s a lot easier that you’re able to send a message and Via satellite get a message back and there’s no miss communications of what’s going on Now if you watch that video I talked about in doing radio Communications and you’re listening to air traffic control If you’re listening to busy airports like JFK or places that are handling a lot of international traffic You might hear someone using CPDLC in their message So to tell something like JFK departure Boeing 1 flight level 360 CPDLC and that’s our way to communicate to them. Hey, we’re connected up on CPDLC So if you need to send me a message instead of blocking up the radios You can do that and they’ll give you radio frequency changes or whatever it is And that’s a way to keep moving and keep the radio traffic down So that’s CPDLC and that’s what he’s talking about with the higher frequency. So hopefully that clarifies it Alright, let’s get back to this movie If you have a rapid or explosive decompression Like what you saw in the video there what you’ll see is misting like you saw there. It kind of got hazy That is actually something that’s real and I was told that in some cases It’s a lot worse than that because what you’re having is a rapid closure right between the temperature and the dew point and so you’ll get Obviously a loud boom and then you can’t see anything at all. So that is a real aspect of what would happen a rapid decompression

Also, it’s gonna get extremely cold. Obviously that there is an explosion where the hull is breached somewhere and outside Usually if cruise is gonna be negative 40 or 50 Celsius. It’s going to be very cold So that’s the other thing. Another thing to keep in mind is there at flight level 3 5 0 so 35,000 feet in the air at that altitude you’re gonna have a roughly 20 seconds of useful consciousness. So if you get into a Explosive decompression situation in real life the first and the very most important thing you can do is get your oxygen mask on It’s gonna take you 1 a few seconds to figure out what is happening because there’s been this loud explosion your ears are gonna hurt and they’re gonna be Ringing there’s gonna be mist everywhere. It’s gonna take you a few seconds to orient yourself and figure out what’s happening So when that happens at first and the very most important thing is get your oxygen mask on there’s been cases where one pilot was Able to get their mask on and the other one was not and through crew resource management Getting a flight attendant or somebody up there to help get the pilot to get his oxygen mask on everybody was okay. However If you both are slow in delaying to get your masks on you can imagine that would be a massive problem So you see him jump out and grab an oxygen mask and try to get it on Tom Hanks first That’s not how it be You’d want to get that mask on yourself and get breathing oxygen because you’re only gonna have a few seconds of useful consciousness So it’s important that you a take care of yourself first and then work on somebody else But it’s definitely important to get that oxygen mask on quickly and start breathing oxygen Because if you don’t get it on and start breathing oxygen quickly You might lose consciousness. And then if the other pilots are in the same situation now, nobody’s breathing and until the plane gets to 10,000 feet nobody’s going to be awake and it’s time to get there until you run out of fuel where you crash So it’s really important if you do get into an explosive decompression Situation that you immediately get your mask on if you remember from I was talking about how that mask Expands in the back so you can put it on with one hand I want to put a clip up here shows you me expanding those tubes in the back so you’re able to grab it and put it on with one hand and those tubes will actually come out and expand so it can Go behind your head when you let go that mask when you let go those clips it now sucks onto your face so we have some like you’re seeing there which is the full face and we have others like you see that Tom Hanks is using Which is just the oxygen side, but they both work the exact same way You release it and it sucks on your face and now you’re breathing oxygen and it’s holding a tight seal around your face Alright, let’s get back to Cast Away Okay, now there’s a lot of Hollywood stuff in that movie and that’s kind of why I’m laughing There’s some things he says like I’m bringing it down and out That’s not something you would ever say even in a normal situation let alone emergency and they’re both all just screaming out words Nobody’s really doing anything in a real emergency something like that You have a quick reference handbook or QRH, and you’re reading through a checklist to do certain tasks So you’re going through those tasks one guy’s reading into the other guy’s doing it or one guy’s reading and doing and the other guy’s Flying, but nobody’s in any situation are both people just screaming out random words and hitting switches That is not how it works on a real emergency When you’ve down to 10,000 feet or 14,000 feet depending on what your company’s policies are and where you’re at flying Obviously, they’re over the oceans of 10,000 feet is fine. But once you’re down to that altitude, you can take your mask off However, they were at 35,000 feet and they got down to 10,000 feet in about a minute. So you’re not going to descend 25,000 feet in one minute for two reasons one planes that go down that fast unless there is something missing like wings and 2, you’re not going to want to accelerate in a descent with a rapid or explosive decompression and here’s why if you have a rapid or explosive decompression, and you don’t know what the Status is or what the hull of your aircraft is looking like and you are now Accelerating your aircraft you might have pieces of the whole that are holding on but it might be out into the wind and if you accelerate you may end up ripping more of your hull apart and Now the whole plane is lost. So if you have a rapid or explosive decompression One you’re gonna want to get down as quickly as you can. Yeah your statuses of your aircraft You’re not going to want to accelerate because that can damage your aircraft even more and a lot of cases What you’ll do is you’ll hit a speed descent mode So you hold that speed and you’ll do your speed brakes? which are those things that come up on the wings to help you slow down and obviously you’re going to pull your throttles to idle and you’re going to go down as fast as you can but while maintaining that speed So that way whatever is out there that’s surviving right now is probably gonna survive at that speed as you go down If you know what this current situation is and that the whole of the hull of the aircraft is fine

well Then you might want to accelerate and get down at the maximum speed that the airplane can go but if you’re unsure Then you’re not gonna want to accelerate like what they’re doing. They obviously had an explosive decompression. Nobody knows exactly what it’s going on So you’re not going to accelerate and you’re not gonna make it down in a minute You’re not gonna get 25,000 feet in a minute. That’s just not gonna happen. All right, let’s get back to the movie You Okay first, that’s the reason why if you’re in a lot of turbulence You’re not going to unbuckle your seatbelt and then stand up without holding on to anything Because if you do that, you might get thrown up into the ceiling and smash your head. So don’t do that. Okay All right. Good talk coach Thanks Because then you may end up having two people hurt and nobody’s getting helped So I know in situations when I’ve been flying with passengers in the back and we’re about to hit some turbulence I usually call ahead to the flight attendants and let them know Hey, why don’t you take your seats? Some pilots will end up calling but if they’re not near a phone, then it can make it even harder for them They may be trying to get to the phone in order to get there to find out what’s going on So in my case what I always do if there’s some turbulence that we’re hitting where I think it’s about to get even worse I’ll just make a PA and say flight attendant to take your seats So they’ll either hold on to something or if they’re near their seats. They’ll sit down and buckle in regardless I want to make sure that they’re safe and that’s why you always hear pilots and flight attendants tell you while you’re seated buckle your seat belt because we don’t always know the turbulence that we’re going to hit in some cases we do know but we don’t Always know and that’s the reason why while I’m up on the flight deck. I always have my seat belt buckled It’s not a big deal Just keep your seat belt buckled and that way if there is any turbulence You’re not getting thrown up into the cockpit into the buttons or anything that is up there and if you’re sitting in the back You’re not getting thrown out of your seat or having anything that is gonna damage or hurt you so it’s important that you do that now on the cargo you saw me laughing when those things were sliding out and here’s why on the front side of those which is For a lateral movement of the plane going forward and backwards There’s these heavy Blockers that are in there and they’re set for each cargo container so it can only move a little bit forward and backwards and on the side you’ll have these latches which prevent it from popping out of its spot or sliding left or right or they’re in these rails so they can’t go and pop out and Every flight if you’re flying cargo before the plane even takes off one the pilots will go Walk the deck and while they’re doing that they’re verifying all these latches are in place for the whole plane And that’s to make sure that if you’re in turbulence or and takeoff or whatever it is when things are moving around that these things Are not flying out of place. So that’s something that is never going to and regardless of how turbulent the plane is Those things are not going to start bouncing around like that. All right, let’s get back to the movie Okay, I’m gonna pause it right there I know when the solely video came out Everybody loved talking about the ditching switch and he says in there ditching switch on So the ditching switch is basically something that’s going to close a lot of the valves now in this scenario The plane obviously has a huge hole in it. You’re gonna go crash in the ocean. There’s five people on board You’re all going to get off in the first 20 or 30 seconds and the plane is going to be lost No matter what so ditching switch in this situation is not going to help you but that’s essentially what he’s saying is ditching switch on was be on Some checklist on some aircrafts. You’ll have a ditching switch Which is too close some of the valves to make the plane float a little longer there in a storm With a huge hole in the plane that plane is gonna be sinking pretty quick anyways So those five guys are gonna get out fine and hopefully get into the raft that Chuck is holding but that’s what a ditching switch is and I just paused because I know in that Sully video a lot of people like talking about the Ditching switch. So let’s finish this video That’s the end of that film now you saw it as they’re coming in there he says I got a visual

Well, yeah, you’re looking at a wall of water So at that speed with that size of an aircraft if you’re looking at a wall of water You’re going to be in a very steep nosedive or facing a huge swell So your planes not going to make it through there? And obviously I realized it was a movie It definitely wasn’t an aviation designed a movie But I wanted to address this because it has a lot of very technical Aspects and I know that a lot of you were looking for some more technical things about aviation So hopefully I answered some questions for you. Now. I put a link to the film Cast Away in the description below It is actually a great movie and Tom Hanks does a fantastic job It is not easy to make a movie that long where you’re basically by yourself. He does an amazing job in the movie So if you haven’t watched it, I definitely recommend it. It is a great movie. All right crew in the comments below Let me know did you like this more technical aspect of aviation as I reviewed this movie or did you prefer Sully which was more? Of a a general overlay. I look forward to hearing from you until then keep the blue side up
