Editing Flap (aeronautics) (section)

=== Flaps during takeoff ===
Depending on the aircraft type, flaps may be partially extended for [[takeoff]].<ref name=perkins-hage /> When used during takeoff, flaps trade runway distance for climb rate: using flaps reduces ground roll but also reduces the climb rate. The amount of flap used on takeoff is specific to each type of aircraft, and the manufacturer will suggest limits and may indicate the reduction in climb rate to be expected. The ''[[Cessna 172S]] Pilot Operating Handbook'' recommends 10° of flaps on takeoff, when the ground is soft or it is a short runway, otherwise 0 degrees is used.<ref name="cessna-172">Cessna Aircraft Company.
