Abstract
Official abstract text for this publication.
A method for detecting a failure of at least one sensor on board an aircraft is provided. The method includes implementing an anemo-inertial loop including obtaining a computed horizontal speed, based on an integration of a measured horizontal acceleration and obtainment of a short-term anemo-inertial speed from the computed horizontal speed; developing at least one intermediate loop parameter based on a deviation between the short-term anemo-inertial speed and the anemometric speed or the airspeed; and observing a failure detection parameter obtained from an intermediate parameter of the anemo-inertial loop and determining the presence of a failure on one of the sensors of the aircraft, based on the value of the observed failure detection parameter.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting a failure of at least one sensor on board an aircraft comprising: measuring a horizontal acceleration; measuring an anemometric speed or an airspeed; implementing an anemo-inertial loop in a computer, the anemo-inertial loop comprising: obtaining a computed horizontal speed, based on an integration of the measured horizontal acceleration and obtaining a short-term anemo-inertial speed from the computed horizontal speed; developi…
