pax here,
In et-Avj fdr traces,
1. The ap Cmd a activated in 1 interval, it is means autopilot can be activated when ias disagree. Even though it willl be off later. Why not directly off by system
At 05:39:22 and about 1,000 feet the left autopilot (AP) was engaged (it disengaged about 33 seconds later), the flaps were retracted, and the pitch trim position decreased to 4.6 units.
2. There is 3 trim nose down commanded by autopilot trim I suppose and flaps retracted when ap cmd a activated,
flaps retract by autopilot / pilot ?
EDIT: it was captain pilot who retract
At 05:39:45, Captain requested flaps up and First-Officer acknowledged. One second later, flap handle moved from 5 to 0 degrees and flaps retraction began.
At 05:39:55, Autopilot disengaged,
Seems the weird activated autopilot made the pilot brave enough to retract the flaps.
unfortunately the autopilot turned off again due IAS disagree. How it can be activated for 33 seconds when stick shaker was shaking?
