Aircraft with electrical fly-by-wire controls, equipped with an automatic pilot
First Claim
Patent Images
1. An aircraft with electrical fly-by-wire controls, equipped with control surfaces capable of being moved by electrically operated actuators, said aircraft comprising:
- controls which are actuated by a pilot and generate electrical control instructions which are sent to a flight control computer;
an automatic pilot operable to pilot said aircraft in place of the pilot, and consisting exclusively of calculation means producing automatic pilot instructions from guidance instructions, of at least heading, vertical speed and altitude, which are put up by the pilot, and from guidance parameters sent to it, wherein said calculation means is connected directly by links to said flight control computer so as to send said automatic pilot instructions to said flight control computer; and
said flight control computer including one control function which produces, either from said electrical control instructions received from said controls and from control parameters or from said automatic pilot instructions received from said calculation means, operating commands and said flight control computer sending these operating commands to said actuators to cause them to move said control surfaces correspondingly.

Abstract
An aircraft with electrical fly-by-wire controls is equipped with an automatic pilot having a navigation computer producing automatic pilot instructions that are sent directly to a flight control computer. The flight control computer produces commands for operating the automatic pilot in respect of the actuators for control surfaces on the aircraft.

said calculation means of the automatic pilot produce, from said guidance instructions and said guidance parameters, three automatic pilot instructions which correspond respectively to a commanded vertical load factor, to a commanded roll rate and to a commanded yaw; and
said controls generate three electrical control instructions which are respectively consistent with a commanded vertical load factor, with a commanded roll rate and with a commanded yaw.
