What’s the minimum airspeed to retract the flaps on takeoff?
Flaps 1, it’s V2 + 11.
Why do we enter the OAT prior to engine start?
It’s so the FADEC can compute the Thrust settings for takeoff.
What is the demonstrated Crosswind for takeoff?
25 knots
(AFM chapter 3 under Demonstrated Crosswind)
Why do we have a trim setting ( besides easing stick forces for the pilot).
It trimmed out for V2 in case you loose an engine.
