VFR BUTTON 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
Avoid selecting code 7500 and all codes in the 7600-7777 range. These codes trigger
special indicators in automated facilities. An aircraft's transponder code is used for ATC
tracking purposes, therefore exercise care when making routine code changes.
AIRCRAFT WEIGHT
Select the weight of the aircraft in which the transponder is installed.

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 encounter.
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 determines the rate of climb necessary for the GTN to assume lift-off for detecting an
airborne state. Refer to the Pilot's Operating Handbook (POH) to determine this value. If the POH does not
include aircraft climb rate information, use the default value of 300 fpm.
