AIR/GROUND THRESHOLD
The air/ground threshold is the groundspeed at which the GTN
transitions from a ground state to an airborne state, and vice
versa. To adjust the air/ground threshold, touch the key to the
right and enter a value. This field has a range of 0 (zero) to 99
knots and is set to 30 knots as a default value.
AIR/GROUND DISCRETE
The AIR/GROUND discrete is active-low, and can be configured to interpret if the aircraft is airborne or
on the ground based upon whether the input is grounded or open. If it is desired for the air/ground state to
be airborne when the squat switch input is grounded, then toggle the AIR/GROUND discrete key to
‗Active for Airborne‘. If it is desired for the air/ground state to be airborne when the squat switch input is
open, then toggle the AIR/GROUND discrete key to ‗Active for Ground‘. The default configuration is
Active for Airborne. See the table below.

GPS ANTENNA HEIGHT ABOVE GROUND
This setting configures the height of the GPS antenna above ground level while the aircraft is sitting on
the ground. Before proceeding, measure the GPS antenna vertical offset (to the nearest tenth of a foot) as
shown in Figure 6-16. Enter the measured value by touching the key and entering the measured value into
the keypad on the display. This field has a range of 0.0 to 99.9 feet.

This setting configures the type of fuel the aircraft uses. Options are AV Gas, Jet A, or Jet B.
