| flaps | Control surfaces on the wings which adjust the effective camber of the aerofoil and hence the amount of lift and drag generated at a given airspeed and angle of attack They differ from ailerons in that the flaps on both wings move in the same direction, so affecting the overall flying characteristics while ailerons on the left and right wings move in opposite directions and are used to roll the glider Positive flap settings (with the flaps deflected downwards) reduce the glider's stall speed and are used for landing and slow speed flight (such as when thermalling) Negative flap settings (flaps deflected upwards) improve the glide ratio at high speeds | en |
