The Piper AutoControl III B is a lightweight automatic flight system using
an advanced design and offering maximum utility and reliability. It operates in
the 5,000 cycle audio frequency range.
The AutoControl III B offers a new concept in flight control. The conventional servo “follow-up” is not employed. It has been replaced by a solid state analytical computer. The Roll responses are controlled by the amplifier, with the aerodynamics of the aircraft supplying the follow-up information, resulting in smooth attitude control. This system is not equipped to control the pitch axis of the aircraft.
