For example, if the DEFAULT VS is set to 300 fpm, if the aircraft is climbing at 200 fpm, the autopilot select zero VS upon engagement. If the aircraft is climbing at 400 fpm, the autopilot will select 400 fpm upon engagement. We suggest using 300-500 feet per minute. CAUTION! Do not select a DEFAULT VS that is too high, or autopilot performance may be adversely affected. 15) PRESS KNOB to exit vertical setup and return to the home screen. 16) Cycle power on the autopilot.
