Title:
METHOD FOR DETERMINING A STATE OF CREDIBILITY OF MEASUREMENTS MADE BY SENSORS OF AN AIRCRAFT AND CORRESPONDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/144126
Kind Code:
A3
Abstract:
This method for determining a state of credibility of measurements made by static and total pressure sensors and incidence sensors of an aircraft comprises the following steps: - determining (31) a speed of the aircraft, from static and total pressure measurements, - determining (33) a lift coefficient of the aircraft from an incidence measurement (31) and from said speed, - determining (39) a mass of the aircraft, - determining (70) if an equation of lift of the aircraft is verified, - activating a state of optimal credibility (74), wherein the measurements made by said sensors are considered to be reliable if said equation of lift is verified, - activating (75, 83) a state of non-optimal credibility (76; 84), wherein the measurements of at least one sensor are considered to be unreliable if said equation of lift is not verified.
