Abstract: A first Flight Control system configuration, and the method to obtain such first configuration, has controllers of effector actuation able to receive commands directly from at least three Flight Control Computers (FCCs). A second Flight Control system configuration, and the method to obtain such second configuration, has retransmitters (RTX) that receive commands from the three FCCs and then retransmit to the controllers of effector actuation. A third Flight Control system configuration, and the method to obtain such third configuration, is a hybrid configuration.

Abstract: Sidestick controller grips are provided with a base, an elongate column grip extending upwardly from the base, a head at an upper end portion of the grip column, and a thumb rest surface extending laterally and upwardly relative to the column grip. The thumb rest surface may be supported by a concave outwardly extending support wall which joins the thumbrest surface at a generally serpentine edge which may extend generally outwardly convexly from a lower region thereof at the column grip to a convex apex region, and then extends from the apex region generally upwardly and concavely to an upper region thereof at the head.
