Patent ID: 8095251

Claim:
A system for monitoring anemobaroclinometric parameters in an aircraft, comprising a primary detection circuit comprising at least one measurement channel, the measurement channel comprising: a mechanical device for measuring static air pressure; a mechanical device for measuring a side-slip angle of the aircraft, a mechanical device for measuring a dynamic pressure, a total air temperature and a angle of attack of the aircraft, and a data-processing device configured to determine anemobaroclinometric parameters from the measurements of static pressure, side-slip angle, dynamic pressure, total air temperature and angle of attack, wherein the system further comprises a least one laser anemometer to measure at least one true airspeed parameter of the aircraft, and to provide a redundant indication of at least one of static pressure, side-slip angle, dynamic pressure, total air temperature and angle of attack during flight using a non-mechanical technology, the laser anemometer being placed in a housing made in the vicinity of the external skin of the aircraft and being protected by a window ensuring the optical passage of the laser rays.
