File Description: This autopilot gauge has been designed to pop-up and provide basic functions for flying light or vintage aircraft. The autopilot can keep the wings level and hold a chosen vertical speed in feet. It has been designed to compliment a Palm EFIS or Palm GPS to add electronic goodness to a basic cockpit. Useful also for users with sensitive controls, aircraft with heavy trim controls or toilet breaks. You may not distribute this gauge without my permission in writing.
