Sideslip correction for a multi-function three probe air data system

摘要

A multi-function probe system that provides redundancy for measurements and compensates for effects of sideslip of an aircraft includes at least two probes that are symmetrically located on the opposite sides of the aircraft, and a third probe mounted on the centerline of the aircraft positioned to directly measure local sideslip with ports that are positioned on opposite sides of the center plane of the aircraft. Each of the probes includes self contained instrumentation for providing signals indicating various pressures. The local angle of sideslip sensed by the third probe is used as a compensation for pressure readings at either of the other probes for determining actual angle of attack, and static pressure.
