VFR

Press the VFR key to select the VOR 1200 squawk code. This value can be set in the System Configuration
mode. This menu item is available when used with the SL70, SL70R, GTX 32, GTX 327, GTX 33, and GTX
330.

TrgrSpd

The TrgrSpd key allows you to edit the aircraft speed that will switch the transponder automatically between
active and standby. See the Auto mode description below. This menu item is available with the SL70/SL70R.

Auto

When Auto mode is selected, the transponder will automatically become active after the aircraft reaches the
Trigger speed. While the aircraft is below the Trigger speed, your transponder will not send any information.
This menu item is available with the SL70/SL70R.
1. In Transponder mode, press Menu/Enter.
2. If necessary, edit the Trigger Speed. Press TrgrSpd. Select the desired Trigger Speed with the Large
and Small knobs. Press Menu/Enter.
3. Press Menu/Enter. Press the Auto key. Auto mode is active when it is highlighted. Press Auto again
when you want to deactivate the Auto mode.

Flight ID

For GTX33/330 installations, the Flight ID can be either tied to the tail number of the aircraft (set at installa-
tion time) or set to another value by the flight crew as needed. The Flight ID key allows you to either just view
the Flight ID or view and edit the Flight ID. For installations that allow editing of the Flight ID, care should be
taken that the Flight ID has no more than 7 characters, is left justified (characters start on the left), and there
are no spaces. This is in accordance with ICAO Doc 8168 [PANS-OPS] Vol. I, Part VIII, 1.3, which states that
flight crew of aircraft equipped with Mode S having an aircraft identification feature shall set the aircraft identi-
fication in the transponder. Refer to ICAO Doc 8168 Vol. I, Part VIII, 1.3 for more information.
1. Press Flight ID to allow entry of a Flight ID. This menu item is available with the GTX 33 and GTX 330.
This allows the GTX 33/330 to view and modify the Flight ID.
