1. A method for spoofing detection of a traffic alert and collision avoidance system, called TCAS;
the TCAS having a Mode A, a Mode C and a Mode S for communicating with surrounding aircrafts;
the method comprising the following steps:
querying a suspected spoofing aircraft via Mode S of the TCAS and receiving a response to this query;
deducing from said response data, called Mode S data, relating to the suspected spoofing aircraft;
validating the Mode S data by querying the suspected spoofing aircraft via Mode A or Mode C of the TCAS.
