Abstract

A rotatable airstream direction probe is additionally provided with a dynamic pressure sensing port positioned substantially midway between a pair of pneumatic sensing ports with respect to the probe's stagnation line. Pneumatic output ports may thus be provided, each of which communicates with a respective one of the pneumatic sensing and dynamic sensing ports in the probe. The pressure outputs from such output ports may thus be indicative of static and dynamic pressure of an airstream so as to be capable of determining flight information of an aircraft such as airspeed, altitude and vertical speed.
