Abstract:
1. An automatic landing method of an aircraft (AC) on a landing runway, wherein the aircraft includes an automatic piloting system, the method comprising: obtaining a slope value of the landing runway and providing the slope value to an automatic piloting system of the aircraft (AC) before the aircraft is over a threshold for the landing runway; automatically determining by the automatic piloting system whether the slope value of the landing runway exceeds a certain slope value, wherein the determination indicates whether the landing runway has an upward slope that exceeds a certification value for the automatic piloting system or a downward slope exceeding the certification value for the automatic piloting system and the determination is made before the aircraft is over the threshold for the landing runway, and if the automatic piloting system determines the slope value of the landing runway exceeds the certification value, said automatic piloting system uses the slope value of the landing runway to automatically manage a flare phase of the aircraft (AC), wherein a management of the flare phase is initiated before the aircraft is over the threshold for the landing runway.
