Lots of comments about flight 447 in reference to this, however, although the information is correct for the onset of an aircraft stall, it will not work once the aircraft has entered into a deep stall, as what happened to flight 447. Pilot error allowed this to happen from which there was no recovery. Simply pitching down will not work. The deep stall has caused the tail and rudder to stall along with the wings......you are going down. R.I.P. all souls on board flight 447
@@JamesAustinTrickShots Recovery at the height you mention is what I initially thought was possible. But I have spoken with experienced commercial flight instructors and fighter pilots. Flight 447 was in a deep stall. There is NO recovery from a deep stall by going 'nose down'
@@JamesAustinTrickShots Lots of reports state lot of things. I've heard that the report was NOT a complete report. 447 was in a deep stall, brought upon my total incompetence and the inability to perform CRM procedures to recognise and recover. There are many other contributing factors of course but they needed to have overcome them before the onset of the deep stall because recovery is then too late
@@fostexfan160 You're wrong. According to Terry Lutz and most other Airbus test pilots, AF447 could have been recovered until it reached about 14000 feet. The flight crew, if they had carried out this procedure and pitched down including some nose down trim, they would have had enough Q from about 25000 feet to effect recovery.
Wow the buffeting is much more violent than I thought. That destroys the theory that the passengers of AF447 wouldn't have even known anything was out of the ordinary. Imagine the shaking at 10:17 but for 4 minutes straight.
Of course you want them to say the truth to their families that they felt everything ? They felt every moment of the stall right and left turn acceleration, up and down everything but they didn't want to say the truth
I think modern day airline pilots are so integrated into the auto pilot that they just give it control and expect it to do everything. Hand flying is becomig a lost skill on the big birds.
Agreed, I am an old breed of pilots (former Air Force as well), where I hardly saw a GPS...I do fly modern aircraft like the A320, ERJ 145 (not really flying anymore FOREVER since last December, where I had 3 heart attacks and an open heart surgery at 56 years of age) and find it amazing, all the integrated systems, but I do a lot of hand flying with simulated emergencies to see how I can handle hand flying the A320 and it is easy as well. Problem is navigation, which is complicated with all that glass cockpit.
AT LAST! Incredibly, someone made a video to tell what so many often don't understand. Stall is AoA related ONLY, not speed related! I now wonder how those who learned that a low speed creates stall will be able to delete this from their mind and understand a basic principle of aerodynamics, which is that a wing will only stall when the angle between the airflow and the wing's chords (from root to tip) is greater than a critical local value for any airspeed anywhere between 1knot and as many knots as the craft can withstand.
man... how can it have been possible for the pilots of flight 447 not felt the buffeting, realized that they were indeed stalling...will hunt me forever what was going through their heads
no matter how much alpha-prot you have no matter what the computers do, you must first and foremost be a pilot. Just as instinct tells you to push the brake pedal in your car when confronted with danger, it should become instinct to push the nose forward to recover from the stall. AoA is dead important and is ingrained in you when. you start you career in that little Cessna.
Well, analogy to automatically pushing brake when in danger in a car is not the best one, it is actually similar to what the pilot was doing: The plane was descending so he was applying more pitch. Same wit car: The car skids outside a curve because of excees speed so you may think of pressing brakes: But you'll most likely either skid outside or spin your car... Same as stalling instead of gaining altitude.

Stall Stall Pilot: Captain, we are stalling. Airplane: brrrrr Captain: That's right. Tell the flight attendant to prepare cabin for landing. Pilot: Roger, what's next? Captain: We will watch this well thought and carefully edited instructional video, preferable at half of its normal speed, so we make sure we don't miss anything. Pilot: Right. I'll get me some coffee. You want a cofee, Captain? Captain: No, thanks, already had one today. Two is too much for me. Airplane: brrrrrrr Flight Attendant (opens the cabin door, steps in): Hello Captain, I brought some popcorn. and the Morning News. Enjoy! Captain: Great! Let's see what we have here (eating popcorn).. Airbus crash possible due to stall.. Hey folks, we are in the news! Airplane: BRRRRRRRRR!! Pilot: Awesome. Captain: Yep! That's our 15 minutes of fame - Pump up the volume and let's watch that beautiful instructional video! Flight Attendant (floating beneath the roof): I feel... dizzy. Captain: Dont' worry, you're ok. It's just the stall. Flight Attendant: Thank God. Video: Every day, thousands of Airbus aircrafts...
Thanks for the training video, but what about adding power after pushing the nose forward and having control the stall, I think it would be a good idea. In low altitudes, bellow Fl 200' requesting Flaps 1 also It helps.
Stalls are by definition "a loss of control" but yes, when you stall you do 2 things: nose down and add power. Only set flaps when you're feeling suicidal though, since it'd only make things worse.
flaps and power push the nose up .. flaps 1 after enough speed to pull up faster.. yea, .. although flaps would be under stress.. but its good idea, f... them. you are in emergency.. let the wing fall first before putting the nose nose down.. its also better.. they didnt teach that in school for years.. and obviously not even today.. and yet plane was saved once because of that after elevator stuck on take off... i think most pilots today with stuck elevator on take off would just die.. delta flight 1080 .. now that was amazing save.. most pilots today would not save that plane..like 90 percent of them..
neonille yes.. is one of the first things they teach you when learning to fly.. in risk of a stall push down stick to reduce angle of attack and keep the airflow attached to the wings.. as for AF447 copilot Bonin held the stick full back all the way down without telling his mates until nearly the end.. when there was barelly 1 minute left he told them "but i have had the stick pulled back all the time!" .. then the captain realiced the mistake and ordered nose down.. but it was too late. Read the report.. the mystery is more how Bonin could have made such monumental mistake that any Cessna pilot is teached well to avoid (In france there was many controversy about "baby pilots" or young guys from rich families who get their licences fast thanks to money and get seats they shouldnt be driving...
sparrowlt thats why i love boeing because whole time you can see your colleague what he is doing with yoke.. two different company two different philosophy
sacit manav All pilots i have talked to say its largelly irrelevant.. Airbus has a warning and each stick has a priority button....that gives you total control.. This crew problem was that they didnt coordinated at all.. the investigation revealed that before the event after the captain went to sleep both FOs were very weird with the other like if each one believed himself the acting captain but without saying much to the other.. when the probes froze Airbus has a very specific procedure called "unreliable air speed/readings procedure".. neither pilot even mentioned that procedure neither asked the other about the controls.. Bonin was the one who stalled the plane and kept the stick back.. but Roberts didnt for a moment asked him what he was doing , or pushed his proority stick button.. It was the captain the one who asked "what the hell they were doing" (literally). Also having the controls mechanically linked doesnt garantee your safety ... that Egyptian 767 in wich the FO crashed it into the ocean.. the captain was seated right there pulling the yoke oposite and that didnt helped much
sparrowlt i am not saying side stick is bad. but in this flight 447 case yoke would save the many life's . because captain was siting back looking the gauges try to understand whats happening. I always imagining what if the captain saw very early yoke pulled back i believe he would aware the situation quick. stall alarm warn them more then 70 times. very long time.....
It did and also degraded the operating mode of the aircraft ( from Normal Law to Alternate Law), which is why the speed protection ( Alpha-floor protection ) did not trigger
Raymond Huang AP turned itself off the moment the probes were frozen at cruise speed.. since the AP and FBW system cant reliable fly the plane they revert controls to manual and to the pilots with a very loud alarm.. If the pilots had not touched the controls nothing would had happent (the probes unfroze 40 seconds later) but for some reason First officer Bonin then pulled back his stick (without telling the other guy) and stalled the plane... and kept it full back all the way until the captain realized and ordered him to nose down (unfortunatelly too late to avoid the impact). look for videos of Airbus A320/330/340 in landings.. you definitilly will notice the AP coming off (loud alarms plus red lights in the master warning ..and you have to push them to clear them)
Thanks a lot, very nice video and information. Appreciated it. Cheers, LCL SUBSCRIBED

anyone say narrator name? the voice of Airbus training.

David Owens even
No no no this is completely wrong. According to Air France during a stall you pull UP instead of push the nose down.
Actually, if you push down, gravity pulls the plane down, thus making the plane regain speed.
Zeckrom_WolfYT Roblox That joke went right over your head.

Scary as hell

Would be a great ring tone!

according to the final report, the pilots thought the buffering was actually a turbulence caused by the storm.
