Abstract: A method and device for optimizing the orientation of a laser anemometer on an aircraft. The device can determine an optimal orientation of a sighting axis of the anemometer and deduce therefrom the orientations of the other sighting axes.

Abstract: A monitoring system including two laser anemometers and a selection logic device able to select, on the one hand, a value of the IAS air speed to be displayed on first display means and, on the other hand, another value of the IAS air speed to be displayed on second display means.

Abstract: The disclosed embodiments concerns a system for monitoring anemobaroclinometric parameters in an aircraft, including a primary detection circuit having at least one measurement channel. The measurement channel includes a device for measuring static air pressure, a device for measuring a side-slip angle of the aircraft, a device for measuring a dynamic pressure, a total air temperature and a angle of attack of the aircraft, and a data-processing device capable of determining anemobaroclinometric parameters from the measurements of static pressure, side-slip angle, dynamic pressure, total air temperature and angle of attack, a least one laser anemometer to measure at least one true airspeed parameter of the aircraft.

Abstract: A method and device for determining anemometric parameters of an aircraft. The device (1) comprises four laser anemometers (A1, A2, A3, A4) that are mounted in pairs (CA, CB) symmetrically on the aircraft and means (4, 5) for determining the angle of sideslip and the angle of incidence of the aircraft, using measurements taken by these laser anemometers (A1, A2, A3, A4).

Abstract: The device (1) comprises means (M1, UC) for determining an optimal orientation of a sighting axis of the anemometer (2) and for deducing therefrom the orientations of the other sighting axes.
