Flaps, slats and other high-lift devices
7 min read
Trailing-edge flaps
Flaps add camber (and some area): C_L max goes up, so the stall speed goes down; drag goes up too. They slightly lower the critical angle of attack and the nose usually sits lower for the same lift.
Small settings mainly add lift (take-off); large settings add mostly drag (landing).
