Method and Device for Detecting, on the Ground, the Obstruction of a Pressure Tap of a Static Pressure Sensor of an Aircraft

摘要

The invention relates to a method and device for detecting, on the ground, the obstruction of a pressure tap of a static pressure sensor of an aircraft. The device (1) comprises a pressure sensor (2) provided for measuring the pressure inside a probe (4), which has a heating system (9) for heating the probe (4) and which, when the heating system (9) is activated, carries out a first measurement of at least one parameter dependent on the pressure inside the probe (4), and a predetermined duration after the activation of the heating system (9), carries out a second measurement of said parameter. The inventive device also comprises at least one central processing unit (11) for calculating the difference between the first and second measurements and for comparing this difference to a predetermined value, and comprises warning means (13) for emitting a warning signal indicating the detection of an obstruction if the difference is greater than said predetermined value.
