Abstract: Disclosed is a method of detecting spoofing of a traffic alert and collision avoidance system, known as a TCAS, the TCAS having a Mode A, a Mode C and a Mode S for communicating with surrounding aircraft. The method includes: querying a suspected spoofing aircraft via Mode S of the TCAS and receiving a response to this query; deducing from the response at least some data, known as Mode S data, relating to the suspected spoofing aircraft; and validating Mode S data by querying the suspected spoofing aircraft via Mode A or Mode C of the TCAS.

Abstract: This electronic device for storing a terrain database for an avionics system is carried on board an aircraft. The terrain database corresponds to a terrain zone likely to be overflown by the aircraft, represented in the form of a surface area divided into meshes, each mesh corresponding to a sector of the terrain zone, the terrain database having a first resolution and comprising first terrain elevation values, each associated with a respective mesh. The terrain database further comprises, for each mesh, an uncertainty value associated with the respective first elevation value, at least one uncertainty value being calculated from a plurality of second terrain elevation values associated with said mesh and from a second terrain database having a second resolution higher than the first resolution.

Abstract: A method for determining a runway to be used for making an emergency landing, implemented in flight by an electronic device on-board an aircraft. The method includes at least one iteration of (i) obtaining, from on-board equipment of the aircraft, data representative of current wind characteristics, at a current altitude of the aircraft, and (ii) determining a runway to be used for the emergency landing, based on data representative of current wind characteristics at current altitude, based on a set of preselected runways, and based on a structure of correlation data between the data representative of wind characteristics at the current altitude and data representative of runways in service on the ground.

Abstract: A method for remotely controlling the flight of an aircraft following a first flight plan, the aircraft includes a communication module connected to a flight management centre of the aircraft, the communication module being suitable for allowing a communication between a terrestrial communication station and the aircraft, the method comprising the following steps:



determining, in the terrestrial communication station, an incapacity of the pilot or pilots of the aircraft,
using the communication module, receiving a first signal that has been coded using a predetermined code and transmitted by the terrestrial communication station, and then decoding the first signal using the predetermined code, which has previously been stored in the communication module,
after the first signal has been decoded, sending, using the communication module, a command to the flight management centre prompting a second flight plan to be followed by the aircraft.

Abstract: Disclosed is a method for detecting decoying of a traffic alert and collision avoidance system on-board an aircraft targeted by decoying. The method includes a phase of establishing a trusted network including the steps of dividing the space into a plurality of zones; and of selecting a verifier in each zone. The method further includes a phase of validation including the steps of generating an interrogation [sent] to each verifier; [a step of] reception of a response to each interrogation and verifying the response; and [a step of] analysis of all the responses so as to either validate or not validate the aircraft suspected of decoying, as false traffic.
