Abstract
An air data sensing system utilizes a plurality of probes, each probe having three pressure sensing ports, and each assembled with a sensor package that minimizes the need for corrections due to temperature or other variations in ambient conditions. The system is mounted on an air vehicle using two or three sets of right and left pairs of probes. The probes of each set are vertically spaced from the probes of the other sets. The probes are made light weight and small. In the arrangement shown the probes provide triple redundancy and because of the orientation on the air vehicle provide all needed pressure and angle information, including the angle of sideslip.
