GLIDE RANGE RING
NOTE: Glide Range Ring options are disabled when Outside Air Temperature
(OAT) is not available.
NOTE: In order for the Glide Range Ring to display on the map, Best Glide
Speed (V
G
) and Sink Rate (at V
G
) must be configured on the Aircraft Con-
figuration Page in Configuration Mode. Refer to the G3X Touch Installation
Manual for more information.
NOTE: Many factors, such as winds at various altitudes, terrain, aircraft
configuration, and pilot actions affect the ability to accurately estimate the
gliding range of an aircraft. The Glide Range Ring is for reference only and is
not a substitute for the Emergency Procedures and glide distance information
in the aircraft Pilot's Operating Handbook.
The Glide Range Ring is displayed as a cyan ring around the estimated area that can
be reached by the aircraft in the configured best-glide range configuration. The Glide
Range Ring fades into view on the map as the aircraft climbs through 500 feet AGL.
The range is based on the configured best-glide Speed (V
G
) and Sink Rate (at V
G
). Best
Glide and Sink Rate are combined with the aircraft's height (AGL), wind, bank angle,
terrain, and obstacles to determine the distance the aircraft can travel.
