pitch is controlled by the rear part of the tailplane's horizontal stabilizer being hinged to create an elevator. by moving the elevator control backwards the pilot moves the elevator up (a position of negative camber) and the downwards force on the horizontal tail is increased. the angle of attack on the wings increased so the nose is pitched up and lift is generally increased. in micro-lights and hang gliders the pitch action is reversed—the pitch control system is much simpler so when the pilot moves the elevator control backwards it produces a nose-down pitch and the angle of attack on the wing is reduced.
