Abstract:
1. A method for aiding the piloting of an aircraft during a landing phase at an airport having a plurality of landing runways, the method comprising: a) determining by a runway determination device one of said landing runways onto which to land the aircraft; b) determining characteristics of the landing runway determined in step a); c) determining by a position determining unit a current position of the aircraft in a reference frame related to said determined landing runway; and d) estimating by an estimation unit, upon the aircraft passing a given height above said determined landing runway, minimum braking distance, wherein the estimation unit: comparing by a distance comparison unit the minimum braking distance with a length of said determined landing runway; and emitting an alert by an alert unit, when said minimum braking distance is greater than the length of said determined landing runway, wherein the alert is automatically emitted in a flight deck of the aircraft and inform a crew that aircraft braking capability is not be sufficient to stop the aircraft safely on said landing runway, wherein said minimum braking distance is estimated in accordance with standard descent plane towards said landing runway and of a performance model of the aircraft which is calibrated on maximum operational braking capabilities of the aircraft.
