Go-around procedures are outlined in FCOM 3.03.
the call is go around flaps, flap handle moved up one place. from 4 to 3 or if its flap 3-from position 3 to position 2. the confusion can arise when cleaning up from flaps 3 take off in the acceleration stage.
f plus accelerating- flaps one. thats normallly the call for a flaps 2 take off when the plane accelerates past the f speed. flap handle goes from 2 to 1.
but in a flaps 3 take off-it goes from 3 to one. same call- f plus accelerating-flaps one but handle goes straight from 3 to 1. then from 1 to 0 as normal above s speed
definitely not to be confused with a flap 3 approach to go around. dont have reference for this-not near an Fcom today
