Meet Piper PA-31T Cheyenne II
The Cheyenne II’s pitch system includes a stability augmentation system that varies the elevator force. Piper’s information manual describes an AoA vane feeding a computer, which operates a servo to alter tension in the elevator downspring. The spring supplies an additional longitudinal force as the aircraft’s condition changes.
History & design
The pressurised Navajo becomes a turboprop
Piper began developing the Cheyenne in 1965 around its Pressurized Navajo. With PT6A-28 engines and wingtip fuel tanks, the PA-31T gained certification in 1972 and entered production in 1974. When the lower-powered Cheyenne I appeared in 1978, the original aircraft became the Cheyenne II.
The models differ in longitudinal stability as well as power. The II retains a stability-augmentation system; the lower-powered I was approved without it. The stretched IIXL moved the empty centre of gravity forward and used a climb-power limitation, allowing another configuration without that system.

An AoA-responsive elevator downspring
Piper’s 1979 information manual explains the stability augmentation system’s vane, computer, servo and downspring. It identifies the purpose as improving static longitudinal stability through variable elevator force. The same computer also supports stall warning and the stall-margin display.
Carenado’s automatic flight
The developer lists a custom KFC300 autopilot and optional RealityXP GTN750 integration. Its engine and propeller implementation was authored for X-Plane 11.30’s engine model.
