Best Airport Bearing Pointer - Garmin G3X Touch Pilot's Manual

BEST AIRPORT BEARING POINTER

NOTE: In order to display the Best Airport Bearing Pointer, Best Glide Speed
and Sink Rate (at VG) must be configured on the Aircraft Configuration Page
in Configuration Mode. Refer to the G3X Touch Installation Manual for more
information.
NOTE: Many factors such as winds at various altitudes, terrain, and even
pilot actions affect the ability to accurately estimate the gliding range of an
aircraft. The displayed Glide Range Ring should not be considered a replace-
ment for normal pilot training to deal with in-flight emergencies.
The Best Airport Bearing Pointer points to the airport within the Glide Range Ring
that is considered the best option for a landing based on the following criteria:
1) The airport must be within glide range as determined by the following:
a) User entered glide performance (Sink Rate and Best Glide Speed).
b) Aircraft altitude and direction of flight.
c) Airport elevation.
d) Wind velocity.
2) The expected flyover altitude (i.e., airports with 1000' or greater margin
take precedence).
3) Hard surface runways (i.e., paved runways take precedence over grass
runways).
4) Runway lengths.
5) Runway alignment with the wind (if known).
