Define dissymmetry of lift:

unequal lift between advancing and retreating halves of the rotor

disk caused by the different wind flow velocity.

When blade flapping has compensated for dissymmetry of lift, the rotor disk is tilted to the rear, called _____________. The aviator uses ______________ to compensate for dissymmetry of lift allowing him or her to control the attitude of the rotor disk.

blowback

cyclic feathering
