Abstract

Un manche de pilotage (M) d’un aéronef, le manche de pilotage (M) comprenant un premier arbre (A1) et un levier de commande (1) configuré pour entraîner en rotation le premier arbre (A1) autour d’un premier axe (A) selon une première plage angulaire [α1 ; α3] par l’intermédiaire d’un joint mécanique (2) présentant un rapport de réduction primaire (RA1), le manche de pilotage (M) comprenant un dispositif de freinage 5 configuré pour freiner le premier arbre (A1) par l’intermédiaire d’un premier dispositif de transmission (TRANS1) présentant un rapport de réduction secondaire (RA2), le rapport de réduction secondaire (RA2) étant maximal pour une position angulaire (α4), le rapport de réduction secondaire (RA2) étant croissant sur la plage [α1 ; α4] puis décroissant sur la plage [α4 ; α3] de manière à obtenir un rapport de réduction global (RA3) ayant une amplitude de variation limitée sur la première plage angulaire [α1 ; α3].
