The Sperry Mark 3 Gyropilot was primarily used in aviation, particularly in aircraft like the Douglas DC-3. It was an early form of autopilot that helped pilots maintain heading and altitude without constant manual control. The system was designed to improve flight stability and reduce pilot workload, making long-distance flights more manageable.
