Hello,

Just trying to understand this "Controllability" issue with B+G failure.
FCOM 3.02.29 staes" Extend landing gear at 200kts, to improve contollability when on a single elevator"
My question is :
1. You are on a single elevator even with B+Y failure.what about contollabilty then?Isn't it an issue there or has it to do with failure of other control surfaces also?
2. By taking gear down at 200kts you are actually going into direct law with aircraft clean (as slats are lost and flaps will come out only when selcted to flaps 2).Isn't it a rather an unusual selection because normally we have some amount of flap/slats before taking gear down.
3. In sim sessions we invariably get a stall warning during this phase with upper and lower barber poles momentarily coming together. Is there any way this can be avoided?
Thanks
