Captain RVV was formally a fighter pilot. now he is doing a great job on this training 👏
This was done in real life. The Gimli Glider is the nickname for a Boeing 767 which ran out of fuel at 41,000 the Captain landed on a abandoned runway
פעם ראשונה בארוץ. איזה כיף לשמוע עברית. 😊
No one ever said pilot training was easy. Loved this video! It had me on the edge of my seat, even though it was a simulation.
Hey Captain Boeing! That was very interesting to see what would happen landing the Queen without engine power. Oh, the things you can try in a simulator! But it does keep you prepared and on your toes! That's always a good thing! Good job Captain RVV! This was fun to watch and listen to, Captain Boeing! I actually got a little laugh watching the two of you at the end as you were drifting off the runway - LOL! 🤣Thanks for sharing some of your 'training' sessions with us -- really cool! Stay safe out/up there! Blessings and cheers always, my dear friend!! 💕✈💕✈💕✈😉😉😉
What is the minimum speed needed to hold the nose up after touch down. At what point with full aft yoke will the nose come down on it own? Another words how much aerodynamic braking can utilized after touch down. Also what was the rate of decent at 250 knots once the gear came down? Very good. I enjoyed this very much.
I don't know the answer on your question, but I can say that the brake accumulators can be used to stop the airplane. They provide 3000 psi but discharge once you release😅
Captain Boeing is always a superb leader and trainer. Very interesting simulator video. Enjoyed this.
You moved the camera too much, and why did you play with the throttles when the engines were shutdown? Otherwise, this was fun.
That was a lot of fun. You came is so fast I was surprised you were able to stop on the runway.
Honestly, me too
Commercial Airplanes have the glide ratio of a brick. When you loose so much trust, the plane can no longer hold altitude, it is going down and there are low odds there will be a runway close enough. Also, the stress factor in a real emergency is way more than any simulated emergency.
Great video, have been searching a long time for this scenario in the sim!
I have some questions:
How was the APU started with all engines on and all AC busses pwrd?
Was the APU used to pwr the grd serv bus in turn powering the batt's?
And did the APU provide bleed air for the DEM pumps (I assume all 4 air driven), if so why did the pneumatic LE's not extend and the gear and TE flaps extend so slowly (with full HYD capability, EDP's and demand pumps)?
Last questions 😅:
Why weren't the APU gens turned on?
Why did you lose hydraulic power on the ground with the demand pumps?
And why does the brake source light flicker?
Sorry for all the questions I'm really trying to understand the 747-400😂😅
Makes you wonder why there's no automatic emergency generator for the hydraulic's.
Excellent simulation. I do this with my Beechcraft Baron sometimes using zero-thrust on both engines.
Just curious: Would aerodynamic breaking after touchdown..by holding the yoke fully back…have created a tail-strike at that speed?
At 250 knots she'd probably have lifted off again. They didn't flare completely to keep ram air pressure high.
@@HotelPapa100 I totally agree!
That was unreal, always wanted to know what happens when you land a 747 with no engine power. I imagine it would be very stressful thing especially if you have a very heavy load. Thanks for showing it. 👍
It's stressful on any airplane, even a glider.
That already happened...
@@XB10001 that is... the whole point of a glider, the only source of stress is if you have a reason to go around like runway incursion, otherwise it's just a landing
@@NoTAtchoum or a rope break during launch, downdrafts close to final (though it is ok if you are at about 1/2 spoilers), miscalculations on approach, etc.
It's not juat having a reason to go around.
I used to fly gliders.
@@XB10001 had a rope incident on takeoff, not a rope break tho, it is indeed scary but you're trained for that and yeah for the approach if you did it right, you're about half speedbrakes, if you have downdrafts just stow them a bit and correct (happens a lot on one of the runways of my home airfield)
On the ground, could you use differential braking to maintain the centerline?
Looks like you can walk away so it was a great landing.
😯 that was tense! Great job landing with all engines out 👍 in the unlikely event…. 744 becomes massive glider ✈️ fly safe have a great day dear Captain ✈️❤️🥰
Excellent Training Video ⭐️⭐️⭐️⭐️ Beautiful ❤️ Such Patience Captain G with a sense of humor ❤️🇺🇸❤️✈️❤️
❤️
Hello dear colleague I wish ♥️ ♥️ ♥️ ♥️ you good flights
Don’t you ever get complacent Captain Boeing…we love you!
That was fun. Enjoyed the video.
But we know a 747 can land with all engines out and do it successfully. Just ask the Canadian pilots who fueled up their aircraft and calculated liters as gallons and ran out of fuel. They glided to and landed at an abandoned military airstrip that now hosted drag races....
767 not 747-400
Gimbli Glider?
Although a nice and funny outcome, I hope you'll never have to deal with such a situation for real. Happy landings from Portugal Capt.
Interesting that the APU doesn’t do much in the air. It’s common to mess about in the 777 sim after a session, with dead stick approaches and the likes. Clearly Boeing redesigned the hydraulics so that you’ve always got a pressurised system.
Congratulations Captain very nice video❤😎♥️
That was awesome Capt!! You are a great teacher!! Thankful it didnt really happen!
SFO = TKO 1988. It happened (due unexpected headwinds).
Lost last main on approach and landed on the APU. Lost the APU on rollout. No casualties or damage to the aircraft.
I was on board.
APU would have to be producing air and electrical to run the ADP’s for hydraulics. Otherwise the flaps would be lowered in FLAPS ALT mode and gear would be lowered in GEAR ALT mode. No air, no hydraulics, unless your airspeed had enough ooompf to rotate the cores fast enough to turn the hydraulic pumps. This was dumb!
Awesome video , great job done by the captain
So would the landing (steering) wheel turn (fail to keep straight) in a real world situation of a total loss of hydraulic pressure? Is that a full hydraulic steering system or a hydraulic assist system? Also, why the attempt of full reverse with all engines out? That doesn't make sense on the face of it, what don't I know here? Maybe it is just opening the reversing engine cowls for added drag? Thank you.
So I guess the only thing the APU on an 747 provides is electricity and bleed air. Looks like some subsystems do not have hydraulic diversity that can be powered by electric pumps powered by the APU.
I cant believe that with working APU steel not enough power to pressurize hydraulic system to provide controls over wheel turn system. As result landing at 230 kts very dangerous.
These Israeli pilot dudes… if you can trust someone in the air , those guys are the best . It’s a type of character that never looses cool .
Formerly
That was an excellent demonstration of an emergency situation and how a well trained pilot can safely land a 747.
Seeing this, makes me wonder how they could not have a better system.
Better APU
Better hydraulics
Braking and steering system needs to last long enough to stop. (ya think?)
Try again, start at FL350 then do a shut off over somewhere like JFK to enable several landing options.
Are you driving the rudder after landing?....back and forth, back and forth....
It's actually very comforting to know that this can be done, thanks for this!
Great, now air line management will shutdown all aircraft engines 6 miles from the airport to save them money 🤣🤣🤣❤️✈️
THAT SHOULD BE PRACTICED UNTIL IT BECOMES JUST ANOTHER NORMAL LANDING! PERFECTION
You are a poor simulator operator if you can't land a 747 with no power!😂😮😅
These clowns obviously don't know their systems very well.
Why was the approach so fast? 230 kts over the threshold! You have flaps? Why not get the speed back nearer to where it should be?
We were high on the approach
But windmill of engines keep hydraulic, you saw what happened at 100 .. because, no hydraulic
@@CaptainBoeing Doesn't the APU keep hydraulics going? Doesn't the 747 have a 'RAT' as well?
@@gzk6nk The -400 has no RAT.
I have done it on a sim. I cut all thrust at 30k ft and landed in the desert, not a strip.
Too bad we can't see airspeed and altimeter the whole way down. Please?
יפה מאוד! 😊
He wrecked the plane you're fired homes
Cessna PPL here. I think this touchdown is quite high at 230KIAS. Normal touchdown speed should be about 160 IINM. More flaps to be deployed on approach. Just my 2 cents.
not a cessna here, the controls can't be moved by sole human strenght, hence why the need the fly fast to windmill the engines in order to have some hydraulic power, since they didn't use apu's help.
…all engines SHUT DOWN…
Full reverser when there is no engine power?
Keep in mind that in a Sim you already know ahead of time and can prepare accordingly. In a real world scenario, emergencies happen unanounced and you only get 1 chance, there are no retakes.
Lol no in a sim it's not mandatory to know everything ahead of time, people arent that stupid.
the Space Shuttle could 😳😳😳😳😳😳
Thats the great thing about aircraft design. They will still fly albeit in a descent as long as you can keep the airspeed high enough. You WILL descend right down to the ground…hopefully to a place that will cause minimal damage.
Generally this sort of aeroplane has a chance of making a straight in approach dead stick if altitude is twice the normal….and care is taken with increasing drag. Rudder effectiveness drops rapidly below 100 kts.
I thought they said the APU was running and providing hydraulics edit : Yeah at 1:40 he says they're running the APU for hydraulics.
A 747 with no motors , it's gonna land someplace .They have a little wind generator to help and E gear drop and a long runway . This did happen at Kai tak Hong Kong . Really good practice .
Would you have deployed the RAT in this situation in addition to starting the APU in flight?
Is the simulator a 747-800? If not, no RAT on other 747s.
Land …yes stop…not so much
WAS PLANE FULLY LOADED?
Kindly allow me to share, one of my best, LAX Night time landings ever?
I had the instructor flame out all three engines at the outer marker in a B727 simulator and I barely made it.
Hahahaha! =D well done, sort of...
Looked like some moves from the Fast & Furious movies after you hit 100 knots
What is your best glide speed? Probably around 300 mph
Armchair expert here:
1:30 The ILS should be working. The Standby Bus was operative. Try a manual entry if you have time.
With no elec power on the main busses, you probably won't be able to control the ADPs (Air Driven Hydraulic Pumps) or the EDPs. In Aux mode (on the ground) you might get hydraulics on system 1 for braking.
Why did you lose directional control on the ground? Differential braking not working? The brake reservoir should have supplied enough hydraulics for a full stop.
I think these big sims are programmed to give the absolute worst result to stop the manufacturers from being sued.
I'm not a pilot, but I assumed he steered off the runway intentionally to give himself more stopping distance while remaining on the airport grounds, and also to avoid hitting approach light structures (and other bad stuff) off the end of the runway.
Thank You. Thank You. Thank You.
Amazing... Entertainment.
Would’ve gone better with apu power for sure.
RAT and APU needed
Your best thriller yet. Thanks, I really enjoyed it.
Nice job👍🏻
Impressive.
I understand the APU can power the hydraulics in case of all engine out. Also each engine can provide hydraulic pressure from windmiling, but what does this mechanism work? How can engine windmiling provide hydraulic pressure?
The N2 rotor on the engine (N3 on a Rolls Royce) is mechanically attached to an "accessory" gearbox. On this gearbox are things like the electrical generator, the engine hydraulic pump, the engine starter and a small electrical alternator for powering the engine computer (EEC). A windmilling fan (N1) draws air into the core of the engine and there will be some rotation of the N2 rotor. Probably not quite enough to run main elec generators, but enough to power the hydraulic pump above a certain airspeed.
Fun!
The landing was safe because the plane was closed to the airport when the aigines stopped working!! All depends on the distance
...and altitude
Good job making the runway. Brakes must have been extremely hot.Thanks for sharing this video, keep up the good work.
👍
First 😃
Every ship is a minesweeper and every airplane is a glider. As someone who has actually landed an actual jet with all engines out, this seemed to be done without much thought or in-depth knowledge of the aircraft. Every aircraft has a best glide speed and a known glide ratio, but they seemed unaware of the numbers even in a general sense. Crews do not train for this exceptionally unlikely event because the probabilities are so low. The only time something like this is normally considered is on takeoff and encountering a flock of birds that FOD the engines. Then you are in trouble because you have little altitude or airspeed to use to survive.
Usually best glide speed = best climb rate speed. It is interesting that best glide is not a published airspeed for larger aircraft. In the heat of the moment I would go with best climb speed.
Best climb would likely be too fast. Best glide speed is 1.3 times the clean configuration stall speed for the aircraft’s gross weight. Best climb speeds for jets are optimized base on multiple factors, including a comfortable pitch attitude for the passengers. The best glide speed for the jet I fly is 70-80 knots below the published climb profile.
What jet did you land dead stick?
@@andrewbergman9315 Lear 35 into KPGA
@@paullynch8887 wow, how did you manage to lose both engines? Is there a references to this anywhere I can read? I thought maybe you had experienced such a failure in a military jet as it is not exactly a common occurrence in civilian jets to lose all engines.
Great video captain!
Bon ane bon voyage 🛫
This is what the simulator THOUGHT would happen, but that's only based on what it was programmed to do
Nobody really knows until it happens.
Awesome !!
if the engines are shut down, why do you keep your right hand on the thrust levers?
even shutdown the turbines are spinning and so opening up the thrust reverser doors provides aerodynamic braking effects
@@andrewbergman9315 if the engines are shit down, there is no reverse thrust. You cannot actuate the reversers in flight on a B747. Even upon touchdown, with no engines operating, reverse thrust is not available.
@@user-wl6bw3jl4nwrong, reverse thrust is actuated by hydraulic power, and not the engines themselves. So you can still open them and redirect whatever breeze your engine is producing.
Any landing you can walk away from is a good landing. Any landing where the aircraft can be used again afterwards is a great landing!
I think maybe people has heard that enough times by now. Please stop.
great sim! but quick question... you came too high too fast... why didnt you tried to do 360 before landing?
I'm hoping you aren't a pilot ;)
Why do you need APU for power for the hydraulics? If ALL engines fail, why did the RAT - Ram Air Turbine not automatically deploy?
You don't use a RAT when you have an operable APU.
Exactly ... actually, at 0:03 you can see that the APU is already running before the engines are being cut off. I shall add that in the 747-400 the APU cannot be started in-flight. Nevertheless, great landing, well done.
@@EndofDescent It can when the engines are shut down.
No RAT in Boeing 747-400
No RAT
What technology😳 unbelievable😳 how coool😮
Any landing you can walk away from...
Noooooo! Stop it!
you should of retracted the flaps after touch down to make the brakes more effective and increase the effect of friction. no?
They wouldn't have had enough hydraulic power to retract the flaps even if it was a logical thing to do. The runway surface looked dry. With so much energy and no antiskid, they would have cooked the brakes/tyres even without the flaps generating lift.
You dont need to do that as you have speedbrakes.
flaps = drag so no, you want them out to produce aerodynamic braking for the same reason he pulled the speed brake lever.
If ever I'm on a plain and we have to land with no engines, please make sure it's this pilot on board!
That was pretty interesting to watch😅
You make it seem like Magic... but its simple science... a Janitor can land the plane. 😂
