Patent ID: 8027783

Claim:
A device for guiding an aircraft along a flight trajectory comprising a plurality of successive segments, said device comprising: at least one navigation database; at least one flight management system which comprises a flight trajectory segment determining section that determines at least one flight trajectory of the aircraft with the aid of data received from said navigation database; a flight computer which carries out processing operations intended for guiding the aircraft along said flight trajectory; and actuators of control members of the aircraft, wherein: said flight computer comprises at least the following integrated components: a flight trajectory receiving section that receives said flight trajectory from said flight management system; said flight trajectory segment determining section, which determines the segment of said flight trajectory which is active; a position error formulating section that formulates errors of position between the actual position of the aircraft and the position that it would have if it were on said active segment; and a guidance law storage that comprises all the guidance laws for the aircraft, corresponding respectively to the various guidance modes capable of being selected and applied to the aircraft, and which are formed in such a way as to formulate all the guidance orders for the aircraft, doing so regardless of the guidance mode which is selected, said guidance orders being transmitted to said actuators.
