What are the advantages of a flapless or reduced flap takeoff and when would you elect to carry one out?
Same for landing config?
More flaps reduce takeoff distance at the expense of reduced initial climb performance. Less flaps improve initial climb performance at the expense of increased takeoff distance.
The same is true regarding flap setting for landing. More flap = less runway required but less climb; less flap = better missed approach/rejected landing climb but more runway required. Usually this is less of an issue, but once in a while a reduced flap setting is required due to obstacles in the missed approach path.
The flap setting used is based on whether runway length or climb performance is the most limiting factor.
