A3XX Flap Retraction
Has anyone else heard of a procedure when retracting flaps where from Flap 3 you retract in stages (Flap 2) before going to Flap 1 even though you are above F speed and accelerating? Any documentation on why this would be desirable or appropriate? Everything I have seen from Airbus indicates once above F speed, you retract flaps (Flap 1) regardless of whether you are Flap 2 or 3.
Thank you.
