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.

Abstract: A method and device for detecting a risk of collision of an aircraft, having a profile unit having knowledge of the terrain profile, a determination unit for determining effective values of particular flight parameters, a checking unit for verifying whether a flight path determined by the effective values is compatible with the terrain profile, and a transmitting unit for emitting a warning signal in case of incompatibility. The checking unit includes at least one element for calculating a height variation due to an energy transfer and a total slope variation generated by a speed reduction, during an evasive action, an element deter mining an evasive course using the height variation, and an element verifying whether the evasive course determined is compatible with the terrain profile.

Abstract: A device and associated method for determining an airport runway state includes a device that determines a runway state and is placed on board an aircraft. The device collects measured deceleration data of the aircraft during taxiing of the aircraft on the runway. Then at least one runway state is estimated from the collected data, and the estimate is transmitted to another aircraft or to a broadcasting center during the other aircraft's runway approach.

Abstract: A method for detecting an error in input of one of the takeoff parameters into a flight management system includes a step of calculating a limit value based on one or more takeoff parameters input into the flight management system. The method further includes a step of comparing the calculated limit value with characteristic takeoff values.
