Hi Adsto,
Welcome to PPRuNe. Difficult first question, as I doubt anybody but the dozen or so Boeing experimental test pilots have any experience of stalling a 737. The closest we get is in an air test where we decelerate at 1kt/sec to the stick shaker and then recover immediately.
As for what you will see, the FCTM gives the usual characteristics:
• Buffeting, which could be heavy.
• Lack of pitch authority.
• Lack of roll control.
• Inability to arrest descent rate.
All of which I am sure we knew already, but as it is co-written by the four most senior Boeing 737 TP’s, then we should regard it as the best authority on the subject.
A more detailed handling description is probably omitted because you don’t actually need this info. I am sure that the logic is that they tell you what the symptoms of the stall are and expect you to recover immediately, preferably in the manner described in the FCTM.
You could try a full stall next time you are in the sim, but be aware that it will probably not be a very accurate model.
Regards
S & L
