Abstract
A multifunction probe for aircraft to determine in particular the static pressure and the total pressure of an airflow located in the vicinity of the aircraft and the angle of incidence of the aircraft with respect to the airflow. The probe includes a movable blade configured to orient itself along the axis of the airflow. The movable blade includes at least one static pressure tap orifice located on one side of the blade and a pressure tap configured to measure the angle of incidence of the blade with respect to the airflow. The probe further includes a pressure measurement device associated with each pressure tap and a device to calculate the total pressure of the airflow as a function of the measurements carried out by the various measurement devices of the probe.
