Not at liberty to discuss details as they are company confidential, but there was a fairly recent incident in a 737 that had an upset where the crew left the autopilot engaged and it defaulted to CWS with pilot input. It was shocking to see the flight envelope they got themselves into before someone finally clicked the autopilot off and recovered.

CWS can create some BAD juju. I haven’t flown the 767-300 in awhile, but I BELIEVE it has that autopilot mode?

How does CWS work in the 737? In aircraft I've flown that had it, you pressed a button on the yoke and moved it. When you released the button the airplane stayed in that position. Does the 767 have this as well?

well, considering yr a "gatorhater" thats understandable.

Didn’t drag it in to the discussion. Drug the scenario in to the discussion. Anyways, back to training for now.

He didn't have a nose low unusual attitude, he had a high rate of descent. We don't know what the nose attitude was but the stable groundspeed from 10,000 down to 3,000 suggests the nose may have been a very few degrees below the horizon at best. His flight PATH was 22 degrees below the horizon. His main problem at 3,000 feet agl was a 10,000 foot rate of descent. I just suggested he may have applied max power and brought the nose up a couple of degrees to the horizon not realizing he was already at a very high angle of attack due to the sink rate. What would you do?

Wait for the NTSB report. They have already alluded to pilot error. Insiders point to this based on CVR and FDR data. Give the process a chance.

If you look at the video it's obvious he went in nose low. It looks to me like they were nose low and popped out of a cloud deck, saw the ground, and pulled up. The nose appeared to track just a little in the video prior to it hitting.

The throttles were at max according to the NTSB. The NTSB said they went to 49 degrees nose low and ended up impacting at 20 degrees nose low. Sounds like an unusual attitude. It is going to be found to be Pilot Error. It sucks for everyone but that's what's going to come out.

You need to be quite and go sit in the corner. You’re making an absolute fool of yourself on this thread. Your stupidity is alarming, and you obviously have no clue what you’re talking about.

What part of the NTSB report stating the aircraft pitched “NOSE” Down to 49 degrees did you not understand?

“Also, about this time, the FDR data indicated that some small vertical accelerations consistent with the airplane entering turbulence. 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. The airplane then pitched nose down over the next 18 seconds to about 49° in response to nose-down elevator deflection. The stall warning (stick shaker) did not activate”.

What do you think the aircraft would do if you brought up the nose 4 up degrees while already at a critical angle of attack? Was the 10,000 feet rate of descent an illusion? How about the radar hit 30 seconds earlier which was 4,750 fpm rate of descent? Another illusion? Most people add power to arrest a descent and also add power put the nose down in a stall recovery attempt. Guess you are different. Glad I don't fly with you.

I can't imagine a stick shaker, which has an input from the AOA vane never not working. Those AOA sensors are just infallible.

My God man, please read the NTSB investigative update of 3/12.
