Mr Phoenix[/QUOTE] Capt. Dubois didn't comprehend why the aircraft was climbing while sidestick was forward [quote]
2 h 12 min 32,4 Dubois: No you climb there // aft -8 deg // up 5 deg
2 h 12 min 32,8 Bonin: I’m climbing okay so we’re going down // full forward 16 deg //up 6 deg
2 h 12 min 34,2 Robert: You’re climbing // full forward 16 deg // up 8 deg
2 h 12 min 39,2 Bonin: okay we’re in TOGA // forward 10 deg // 0 deg
2 h 12 min 41,9 Bonin: On alti what do we have here? // forward 10 deg // down 3 deg
2 h 12 min 43,8 Dubois: (…) it’s impossible // aft -4 deg // down 3 deg
I may recall incorrectly, but weren't they already falling by the time Captain Dubois arrived in the cockpit? I guess I need to go back to the thread and find the altitude traces to match up with your time data points there ... will get back to you when I have found it. What I recall is that around 1410 the event began, and they fell from FL 33-35 to the surface in the following four minutes. So, at 1412 the falling toward the sea surface, in a stall, was already in progress. However, I may have recalled that incorrectly.

Thanks.
