A scary situation 😬 thanks for taking us on the flightdeck to see the procedures!

Amazing Videos! These are very informative of what pilots actually do when they get faced with these situations :) Also thanks for taking the time to make these videos :)

Really interesting and thank you for sharing these videos those give us pilot POV and his training.

I hope there's a Part 2! Showing how a suitable airfield is located and the plane is successfully landed. Much later!

The 747-8 is going to become the 757 everyone will want it once they stop making it. You can’t call it a gas guzzler with 787 engines. In testing they took off with a take off weight of 1 million pounds. MTOW is 975,000 pounds that’s incredible. Large aircraft are going to be needed. The 777-300f it wasn’t meant to be a freighter. The MTOW will be limited and the cycles are going to be limited. The 747 is going to be in high demand.

The 747 was designed to capitalise on the freighter market in the event that it was no longer needed in the passenger market. It's pretty evident when you look at the 747's design, the hump is clearly not there for cosmetic purposes. The mindset was that, at the time, there were talks of supersonic jets replacing turbofans in the passenger market (not to mention that passenger travel demand can rise and fall on a dime, unlike freight). It still ended up being pushed out of the pax market in favour of twinjets like the 777, 787 & A350, so you could say that Boeing used the wrong formula and got the correct answer

Thanks, Skipper. I thought they would set the throttles to idle and also make a MAYDAY call to ATC.

They would normally but this was me showing you what you would have left in terms of power etc.

Awsome! Not the failure obviously, but the video. Dumb question: is there a ballpark best glide speed or attitude for a 748, like in GA planes? If so, is it a function of weight? I've noticed the speed hovering around 240 KIAS on the PFD... Cheers from Brazil 😍👍👊

@pilot_obet7815

Hi- yes there is. In general the best hold speed is a good one to maintain.

Hello, capt, I have just recently subscribed, however I do have one question. If all 4 engines flame out, wouldn't the descent rate be greater than what was indicated on the PFD at around 3:50? I have no authority to speak for the handling of the 747 in an all engine flameout as I have never flown the plane nor am I a pilot. Thanks for replying.

@pilot_obet7815

Yes it can initially while establishing the required speed but will settle to normal descent rates for aircraft weight

I had one engine do this in my PS1 and PMDG sims. With the procedures it restated. But all four engines?

Hi capt, just a general question, do airlines take pilots' preference into consideration before ordering new planes, or is it purely based on cost and performance?

Cost….it’s about money😊

@TheGamerUnknown

Minor additional note: If two aircrafts have similar cost, efficiency, capacity, etc - they may partially decide based on re-training costs. Some newer/revised aircraft may not require (or require little) re-training, which saves an enormous amount of money. That's part of what caused the 747-MAX debacle.

This might be a stupid question, by why can't the APU power the hydraulics?

The spool down sound is really a nightmare

why didn't they turn on the batties, engaged the apu and tried to restart the engines?

So when this happens over a volcano for example, will the ash slow the engine restarts? How long of a glide does the plane have in the mean time in case of a dead stick landing?

Thanks for the video Obet. I asked you before about the Ram Air Turbine. ... I've got a couple of questions to ask ... with an ALL engine flame out, why doesn't the RAT deploy automatically/immediately and does the RAT not provide any electric at all? If it doesn't, how long can the aircraft survive without any electrical power being generated.

@pilot_obet7815

2 жыл бұрын

Hi- I think in my narrative I mentioned that it deploys automatically when more than two engines fail but its a belts and braces thing that we still manually activate the switch. the aircraft has 4 generators so for the rare occasion that yo may lose 4 engines, what you need is hydraulics more than electrical. Yo cannot start the APU in flight on the B747 for same reason- extra certification would be required for it on an aircraft that already has good redundancy.

Twin engine aircraft like the B777/737/A350 etc need it as if they lose an engine, then they are immediately on 50 % thrust and only one generator. The likelihood of 4 engines failing although possible and has happened is still rare and 4 engines is good redundancy.

Also attempting to start APU eats up a large chunk of available battery, so it's best be really sure. But battery alone is enough to power critical systems for as long as she can glide, which is gonna be the limiting factor especially from ten k, that's gonna be curtains in less than ten minutes

Does the FO screen always go off when all engine failure as seen in the video? If yes why does that happen

Yes because the aircraft is now on standby power. To conserve it for a longer period, the F/ O instruments are removed.

This is what I hate about air breathing engines. After 90 years, the grains of ash bring them down. Warp engines don't stall from volcanic ash, only nebulae. Need warp drive by now, for gawdssaykes!!!!

@@furzkram You cannot start the APU on a 747 in flight. It was never designed to be used for such purposes. The 744 has 4 engines & 4 separate electrical generators. This is a huge amount of redundancy. An APU is not really providing much back up. You are thinking about twin engines & two separate sources of electrical power & therefore less redundancy for critical systems. Loose one engine on a 744…not really a big problem.

What's the chance of having multiple engine failure on a Boeing 747?

@ImperrfectStranger

2 жыл бұрын

Very little. Volcanic ash, extreme cold and bad fuel are some of the things which can take out all engines. Stopping flights near active volcanoes and updated procedures when encountering volcanic ash greatly reduce that risk. Bad fuel is rare and because old fuel is mixed with new fuel on most flights, the chances of engines flaming out simulataneously is not likely. The 747 has a fuel temperature warning system, so cold temperatures should not be a problem. You just fly faster and lower.
