VFR Key Code
Input a VFR transponder code by touching the key and typing
the selected code into the keypad. This field has a range of
0000-7777.
NOTE
Exercise care when making routine code
changes. Enter only valid VFR codes.
Avoid using code 7500 and codes in the
7600-7777 range, as these codes trigger
special indicators in automated facilities.
Aircraft Weight
Select the weight of the aircraft in which the transponder is installed.
Table 5-53. Aircraft Weight
Selection Description
<15,500 LBS Configures the aircraft weight to less than 15,500 lbs.
>=15,500 LBS Configures the aircraft weight to equal to or greater than 15,500 lbs.
ROTORCRAFT Configures to rotorcraft use.
UNKNOWN Aircraft weight is unknown.
Auto Standby Delay
This is the number of seconds the aircraft must be on the ground before the transponder automatically
switches to GND mode when it has a means of determining the aircraft is on the ground. It has a range of
0 (zero) seconds to 99 seconds. The default value of 24 seconds is a nominal value for most aircraft. This
value can be changed depending on the types of operations the aircraft is expected to perform.
Altitude Climb Rate for Airborne Transition
This is the climb rate that is required in order to transition from ground to airborne state. This field is
adjustable from 100 fpm to 9999 fpm. This field should be set to the typical vertical speed climb rate of
the aircraft. This number determined the rate of climb necessary for the GTX to assume liftoff for
detecting an airborne state. Refer to the Pilot’s Operation Handbook (POH) to determine this value. If the
POH does not include aircraft climb rate information, use the default value of 300 fpm.
