1. A method for verifying coherence of takeoff parameters of an aircraft from an airport with an available runway length at a moment of takeoff, the method comprising:
- identifying a takeoff runway, including the following steps performed by a processoracquiring a position of the aircraft on a ground,extracting position data of a set of takeoff runways of the airport from an airport database,comparing the position of the aircraft and the position data of the set of takeoff runways of the airport with a view to identifying the takeoff runway, andalerting a pilot to signal disagreement between the identified takeoff runway and a planned takeoff runway provided during preparation for takeoff; and
validating takeoff parameters, includingcalculating a takeoff distance from one or more of the takeoff parameters by calculating a single phase of ground roll having a length equal to a real takeoff length corresponding to a phase of ground roll and a phase of initial climb to a predetermined altitude,extracting an available runway length associated with the takeoff runway identified in the airport database,determining a remaining runway length from the available runway length extracted from the position of the aircraft, andcomparing the calculated takeoff distance and the remaining runway length and authorizing takeoff of the aircraft if the calculated takeoff distance is shorter than the remaining runway length.

Abstract
A method for verifying coherence of takeoff parameters of an aircraft from an airport with an available runway length at a moment of takeoff comprises a step of identifying a takeoff runway and a step of validating takeoff parameters with a view to authorizing takeoff of the aircraft if the takeoff distance is shorter than the remaining runway length associated with the identified takeoff runway.
