Abstract
Systems and methods for determining angle of attack (AOA) for an aircraft are disclosed. In implementations, a kinematic AOA signal and an aerodynamic AOA signal are determined based on measurements received from an airspeed sensor and an inertial reference system (IRS) or attitude and heading reference system (AHRS). The kinematic AOA signal is low pass filtered and the aerodynamic AOA signal is band-pass filtered. A blended AOA signal for the aircraft is then determined by summing the filtered kinematic AOA and aerodynamic AOA signals.
