Claim:
1. A method for the automatic detection of an incorrect measurement of a total temperature provided on an aircraft, wherein it comprises at least the following automatic steps, implemented repetitively: monitoring a measured total temperature, provided by a temperature probe of the aircraft, in order to be able to detect a first condition according to which an increase of said measured total temperature is greater than a predetermined threshold temperature over at least a first predetermined period of time; monitoring the measured total temperature, provided by the temperature probe, in order to be able to detect a second condition according to which said total temperature at an end of an increase is situated within a first temperature range around 0° C.; monitoring a received current altitude of the aircraft, in order to be able to detect a third condition according to which any variation of said received current altitude over said first predetermined period of time remains below a predetermined altitude threshold; monitoring a received current Mach number of the aircraft, in order to be able to detect a fourth condition according to which any variation of said received current Mach number over said first predetermined period of time, remains less than a predetermined Mach number threshold; and, detecting an incorrect measurement of the total temperature when said first, second, third, and fourth conditions are met simultaneously.
