Autopilot
ATA Chapter 22 — N720AK Systems Reference
Overview
N720AK uses the Dynon 3-axis autopilot integrated with the Skyview HDX EFIS. The system provides roll (aileron), pitch (elevator), and yaw damper servo control. The autopilot is controlled via the Dynon autopilot panel on the instrument panel and can be disconnected instantly via the red button on the Tosten CS Military stick grip.

How It Works
Control Wheel Steering (CWS)
The Dynon autopilot supports Control Wheel Steering mode. Press and hold the autopilot disconnect button on the stick grip to temporarily override the autopilot, manually fly the aircraft to a new attitude/heading, then release the button. The autopilot will hold the new state. This allows quick course corrections without fully disconnecting and re-engaging the autopilot.
Disconnect Logic
The autopilot disconnects when:
- The red disconnect button on either stick grip is pressed
- Manual force is applied to the controls (servo clutch slip)
