초록

A flight control limiting system for a rotary-wing aircraft which generates servo-commands for at least one of a main rotor and a tail rotor. A set of first commands represents the position of at least one flight control which is movable between extreme positions, and may be controlled by the pilot. A set of second commands are generated by a flying aid system. The flight control limiting system limits the values of the set of second commands when the position of any of the flight controls is close to an extreme position, so that the servo-commands for t...

청구항

[ We claim:] [1.] A flight control system for a rotary-wing aircraft, said flight control system generating servo-commands for at least one rotor of said aircraft, said servo-commands being calculated on the basis of:first commands that represent a position of at least one flight control comprising at least one of a collective pitch lever, a cyclic pitch stick, and a rudder bar that can be moved by a pilot of said aircraft between first and second extreme positions; andsecond commands generated by a flying aid system, wherein said flight control system c...
