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 330 installation must comply
with current transmitter licensing requirements. To find out the specific details on whether a particular
installation is exempt from licensing, visit the FCC web site http://wireless.fcc.gov/aviation.
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. The
GTX 330 owner accepts all responsibility for obtaining the proper licensing before using the transponder.
The UHF transmitter in this equipment is guaranteed to meet Federal Communications
Commission acceptance over the specified operating temperature range. Modifications to
Garmin equipment not expressly approved by Garmin could invalidate the license and
make it unlawful to operate the equipment.
For non-US installations consult the local spectrum management agency for
requirements.
