3.1

AIRCRAFT STATION LICENSING REQUIREMENTS

The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion to
eliminate radio station license requirements for aircraft and ships. The GTX 327 installation must comply
with current transmitter licensing requirements. To find out the specific details on whether a particular
installation is exempt from licensing, please see FCC Fact Sheet PR 5000 or contact the FCC by phone at
800-322-1117.
If an aircraft license is required, make application for a license on FCC form 404, Application for Aircraft
Radio Station License. The FCC also has a fax-on-demand service to provide forms by fax at
202-418-0177.
The GTX 327 owner accepts all responsibility for obtaining the proper licensing before using the
transponder.
3.2

OPERATION

The coverage you can expect from the GTX 327 is limited to line of sight. Low
altitude or aircraft antenna shielding by the aircraft itself may result in reduced range.
Range can be improved by climbing to a higher altitude. It may be possible to
minimize antenna shielding by locating the antenna where dead spots are only noticed
during abnormal flight attitudes.
The GTX 327 should be turned off before starting aircraft engine(s).
If the GTX 327 is configured with Automated Airborne Determination, flight
operation is automatic and not dependent on user mode selection. Whether STBY,
ON or ALT is selected on the ground, the transponder annunciation continues to
indicate STBY and does not respond to radar or TCAS interrogations. When liftoff
is sensed, the unit automatically selects the ALT mode.
