Scary: Southern Air 777 Has Stall Incident On Takeoff From JFK

Damn bruh

Don’t 777 pilot train for power on stall? It shouldn’t be a big deal right, it’s part of regular training...

Are the speeds listed ground speed or air speed?

Thanks for posting. I know it has nothing to do with the normal reviews or miles/points redemptions but I find it fascinating. Love the break down and insights of the 777 pilot.

Typically in a stall you would lower than nose the decrease the angle of attack. The loss of altitude was probably deliberate to gain airspeed and break the stall. I doubt they were in a full power in stall.

Most very heavily loaded aircraft departing JFK request a high speed climb before their departure. This crew apparently didn't. While this "stall' wasn't anything like a nose over uncontrolled rapid descent, it did result in some loss of altitude before the high speed climb was requested and initiated. As a former military pilot, I can tell you that these situations are included in simulator training. At their weight, the request probably should have been an item in their checklist I'm thinking.

Flying straight to ICN as well huh? Can’t imagine how ouch fuel they were carrying!

According to the chart, the airplane climbed from 1,425' to 2,300' in only 12 seconds. That works out to 4,375 fpm during that segment. Since that kind of climb rate would obviously not be in the profile at that altitude and configuration (the aircraft should be shallowing it's climb rate in order to accelerate), and a premature flap retraction would not generate an increased climb rate, I gotta believe the pilots over controlled the pitch either through inattention or lack of finesse, which resulted in the airspeed decrease, altitude surge, and corresponding stall warning.

Or possibly but less likely, a computer malfunction. But if a computer did that, and they knew it, they would be fools for continuing the flight with a known computer issue.

This doesn't make sense as written. A sophisticated modern aircraft should not allow itself to get near a stall situation. It should 'shake the stick' upon a climbing departure that is too slow too steep or indeed any situation where the control software senses a too high angle of attack.

As a retired airline Captain (did not fly the 777) and current simulator instructor, I can say with certainty...something "went ugly early". Either a data entry error in the FMS caused incorrect reference speeds, or (more likely) a simple over-pitch shortly after rotation. I see it not infrequently in the simulator during training events.
Yes, stalls are practiced in virtually all configurations with the INTENT to never have it happen in line operations. Should a low speed / high angle of attack event occur, crews are trained to recover, but it SHOULD NOT happen. In this case recovery was made (albeit scary) with minimum loss of altitude...and my guess...maximum soiling of underwear.
