of course...but...if you are only trained to recover as in an approach to stall...but never, never, never train for a full stall...you will react incorrectly in a full stall...which this flight crew seems to have done.
Agreed. Unfortunately full stall/recovery maneuvers are not required training... as they should be.
During sim training, after all required syllabus items have been completed per the FOTM, I have the students "demonstrate" other important flight characteristics unique to the aircraft they will be flying, including deep stall recognition with recovery.
Fred T. Ruckus of the FAA does not want any maneuvers not contained within the FOTM entered on the training forms.
It took many years to require jet upset as part of the training program.
As manufacturers say... airlines buy airplanes to be flown, and not stalled, intentionally or otherwise.
