Re: Atlas Air 767
Something tells me that this investigation is going to go quiet til the final report
Re: Atlas Air 767
sounds like the autopilot went into antistall or go around and the elevator failed.
Turbulence broke the old plane and it crashed.

Re: Atlas Air 767
Can you expand on the antistall system and it's operation?
Is go around also a function? 6000' seems like an odd place for a go around?

Re: Atlas Air 767
no, i was just making something up as per the previous comment.
However, the quick release from ntsb said they hit turbulence and shortly after nose dived.
Why else would throttles go full?

I think it would be unusual for autothrottle to remain at full thrust in a nose dive?

Re: Atlas Air 767
Power causes most aircraft to pitch upward. Flight control problem, can't control pitch, so worth a shot with power. I could see it as a last ditch effort to try and save the day.
Hypothetical discussion, I know nothing of the actual details.

Seems to say it all right there....LETUN wrote: ↑Tue Mar 12, 2019 8:48 am From NTSB, released today:
. Shortly after, when the airplane’s indicated airspeed was steady about 230 knots, the engines increased to maximum thrust, and the airplane pitch increased to about 4° nose up and then rapidly pitched nose down to about 49° in response to column input. The stall warning (stick shaker) did not activate.
FDR, radar, and ADS-B data indicated that the airplane entered a rapid descent on a heading of 270°, reaching an airspeed of about 430 knots. A security camera video (figure 4) captured the airplane in a steep, generally wings-level attitude until impact with the swamp. FDR data indicated that the airplane gradually pitched up to about 20 degrees nose down during the descent.

Possibly left the speed brake deployed from the crossing restriction. What speed does the 767 maintain if doing a LVL CHG? 245?C-GGGQ wrote: ↑Wed Mar 13, 2019 3:27 pmSeems to say it all right there....LETUN wrote: ↑Tue Mar 12, 2019 8:48 am From NTSB, released today:

Re: Atlas Air 767
It was the 49 degree nose down in response to control input. Not the 230 kts I was pointing to...ReserveTank wrote: ↑Wed Mar 13, 2019 3:54 pmPossibly left the speed brake deployed from the crossing restriction.

Re: Atlas Air 767
If you read the previous posts or reread the current linked article it was changed to read "elevator deflection" and not "column input".
If it was intentional, I'm sure you'll hear the other two people in the cockpit fighting it and case closed. If you hear all 3 wondering what the @#$! happened, then it would be something else.

Re: Atlas Air 767
This accident has me worried. Jump seater from other airline. Reminds me of fedex in the 80’s. I really hope that my fears are wrong.
Re: Atlas Air 767
The jump seater just got hired at a major (American?) and was supposed to start ground school shortly.

United. They gave him his wings and left his seat empty in the class.

Re: Atlas Air 767
Take it for what it's worth...
"Got this info from my airlines unofficial forum. Unofficial of course .
The initial bobble is from turbulence at 6200. When the FO called for flaps 1, the captain accidentally hit the toga button. Toga didnt engage until after flaps were set to 1, which then brought engine power to full, and started the initial pitch of 10 degrees nose up. The FO was startled, and shoved the nose forward... The CVR is startling, and baffling. The CA was pulling so hard against the FO that he sheared the pins on the stick and at that point had no control. They were IMC at the time. When they broke out into VMC, the FO said oh schit and started to pull. That was the round out you see. I wont get into anything more until everything comes out. The records, the CVR, and what happened in the flight deck is truly shocking. They hit a negative 4 G dive initialy on the FOs push. All you hear is stuff hitting the ceiling and at one point a loud thud. They think the thud may have been the JS hitting the ceiling and maybe not wearing the shoulder harness. Like I said, I wont get into anything more about the background of how it all happened. This is the accident in a nutshell. The facts that will come out are shocking."

Same being reported by wall street journal, business Insider etc. Just not in quite that graphic detail.
