Abstract
The invention relates to the automatic stabilisation of aircraft, inter alia helicopters. The position of the anchorage point of piloting channels, inter alia for roll and pitch, is determined by trim motors disposed inside mechanical relays. On the basis of data received from a control column and from an automatic pilot which acts on servo controls, a logic arrangement controls parallel electronic switches which by way of parallel lines permit energisation of the trim motors in a motor priority order determined by action on the bases of the electronic switches.
