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.
