Navigation Basics

Auto Descent

The Auto Descent feature allows you to input a desired End Altitude, an Offset Distance from a desired Auto Descent Waypoint from the Active flight plan, a desired Feet per Minute Descent rate, and an expected Ground speed. It then automatically calculates the distance remaining in your Active flight plan to the desired Auto Descent Waypoint and, based on the calculated glide path angle, your present altitude, and the altitude you are descending to, alerts you with a message when you should begin and end your descent. A Nav item field displays information indicating how much time remains before you should begin Auto Descent, and once Auto Descent begins, whether you are above or below your intended Glide Path. Glide Path data may also be output to an optional Vertical Deviation or HSI Glide Slope Indicator.

Each time you begin to edit the Auto Descent values, the End Altitude is automatically reset to 1,000 feet over the altitude of the desired Auto Descent Waypoint, if the waypoint is an airport. Otherwise, the End Altitude automatically resets to 2,000 feet. In addition, the default Auto Descent Waypoint is automatically updated, as long as Auto Descent is OFF, to the current TO waypoint each time a waypoint sequence occurs.
