Abstract
The present invention relates to haptic feedback for operating at least one manual flight control device () for controlling the cyclic pitch of the blades () of a rotary wing () of a hybrid helicopter () via power assistance (). Said operations of said control device () are defined according to a predetermined damping force relationship (A) that is a function of an instantaneous load factor of the hybrid helicopter () in such a manner that the instantaneous load factor is maintained between its minimum and maximum limit values in proportion to a position of a thrust control member () between its minimum and maximum thrust values ().
