Abstract
The invention relates to a method for estimating the air flow rate through an aircraft air vent (100), at least two pressure sensors (103) being positioned along a pressure measurement extraction line (104) on or near a lip (102) of the vent, comprising calibration and correlation steps. The calibration step comprises generating a database associating for each of at least two air flows applied to the vent, the values of at least two air flow characteristics, and the pressure distribution measurements along the measurement extraction line. The correlation step comprises measuring a pressure distribution along the line (104) when the aircraft is in flight; and correlating the measured pressure distribution, associated with the values of the two characteristics, with the database data, to estimate said air flow rate when the aircraft is in flight.
