Process and device for verifying the consistency of the measurements from an angle-of-attack probe
First Claim
Patent Images
1. A process for verifying the consistency of measurements made by at least one angle-of-attack probe (2) mounted on an aircraft, wherein:
- at least one measurement is made by means of said angle-of-attack probe (2);
a first coefficient of lift of the aircraft is computed from said measurement and from data relating to the aircraft;
a second coefficient of lift of the aircraft is computed from information available about said aircraft;
the difference is computed between said first and second coefficients of lift of the aircraft; and
from this is deduced;
if the difference thus computed is less than a predefined value, that the measurement made by the angle-of-attack probe is consistent; and
otherwise, that said measurement is inconsistent.

Abstract
A process and a device for verifying the consistency of the measurements made by an angle-of-attack probe (2) mounted on an aircraft. The device (1) includes:
first system (3) for computing a first coefficient of lift of the aircraft from a measurement from the probe (2) and from data relating to the aircraft;
second system (5) for computing a second coefficient of lift from information about the aircraft;
system (6) for computing the difference between the first and second coefficients of lift and for deducting therefrom that the measurement is or is not consistent.
