ABSTRACT:
A system for correcting errors in static pressure, airspeed or airspeed rate caused by maneuvering that causes variations in static air pressure measurements compares a barometrically derived vertical velocity or altitude signal with an inertially-derived vertical velocity or altitude signal to provide a correction signal that is representative of changes in static air pressure and is used to correct the static pressure, airspeed or airspeed rate signal.
