Method for detecting the failure of a pressure sensor on an aircraft anemometer installation, comprises measurement of difference between two pressure sensors and comparison with threshold

摘要

The detection equipment (1) consists of two pressure sensors (5) in the anemometer installation (2). The pressure sensors have independent probes (4) and are connected to a calculator (11) through analogue /digital convertors (8) and electrical connections (12). The calculator computes the difference between the two signals and if it exceeds a threshold sends a warning signal (15) to a display (13) in the pilot cabin An Independent claim is also included for: A detection equipment which includes two pressure sensors, means to compare the difference between the pressure sensor signals and means to compare the difference to a threshold and if necessary send a signal to the pilot cabin
