1. In apparatus useful in controlling an aircraft flight path on the final approach to landing, there being a localizer beam transmitted rearwardly toward the aircraft from the landing area, and there being an inertially responsive unit on the aircraft, the combination comprising(a) dual antennas carried on the aircraft and spaced apart laterally to receive said beam, and(b) means responsive to the beam signals received by the two antennas to coact with said inertially responsive unit to produce an output for controlling banking of the aircraft so as to minimize deviation of the aircraft inertial flight path from a vertically and rearwardly extending plane at the center of said localizer beam.
