Abstract: A method and a device for automatically detecting an incorrect measurement of a total temperature on an aircraft. The detection device comprises several monitoring units configured to monitor the variations of the measured total temperature, provided by a temperature probe, and current values of the Mach number and of the altitude of the aircraft over a predetermined monitoring period of time, and a detection unit configured to detect an incorrect measurement of the total temperature when said monitoring units simultaneously detect particular conditions relative to said variations.

Abstract: A method for detecting erroneous air data on an aircraft includes determining a current air parameter and a current altitude pressure parameter which collectively define a current point of control for the aircraft. The method also includes verifying whether the current point of control is situated in a characteristic envelope indicating operating limits for the aircraft. When the current point of control is outside the characteristic envelope, then a detection piece of information identifying at least one of the parameters as an erroneous parameter is emitted, which causes that erroneous parameter to be invalidated and an alarm signal to be sent to the crew. Therefore, an erroneous air data parameter is readily addressed and discarded using the method and associated device.

Abstract: An aircraft is equipped with engines, each engine having at least one pod and one compressor/turbine hitch. The aircraft has at least one data processing unit and at least one system at the engine level. At least one engine is equipped with at least one static pressure probe for measuring the ambient air under the pod. Also, air static pressure probes are arranged at the engine levels, with one pressure probe at the output of the compressor, at least one rotation speed sensor, for example of a blower, and ambient air temperature probes at the air input or in any compression point. The processing unit is able, from measurements performed by such probes at the engine level, to supply to at least one of the systems at the engine level, determination data for the air speed of the aircraft.

Abstract: A device for electrical distribution in an ignition system of an engine of an aircraft provided with a primary electrical supply and a secondary electrical supply, a primary igniter, and a secondary igniter, is provided with an electrical supply system adapted to supply at least one of the igniters alternately via one or the other of the electrical supplies. The electrical supply system is provided with a switch adapted to supply one of the igniters to which it is connected via one or the other of the electrical supplies. A detecting means detects if the igniter that is connected to the switch is also connected to the other electrical supply. The switch may have a relay supplied via one of the electrical supplies so that, in the event of defect of this supply, the igniter to which the switch is connected will be connected to the other electrical supply.
