Takeoff flap setting
We are having an ongoing debate of the pros and cons of flaps 1 vs flaps 2 T/O on the Airbus 320. Ever since FlySmart has incorporated the optimizer for takeoff flap setting, which has consistently applied flaps 1.
I am hearing a number of completely erroneous arguments; such as better second segment climb ( which has just the opposite effect ) or inertial pitch with engine out changing from 12.5 to 10.2 or to much of increase in takeoff V speeds. To the more acceptable, airport with a rough runway.
What are your operations procedures?
Thoughts?
