1.5 License
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 GNC 420W, GNC 420AW, GNS
430W and GNS 430AW installations must comply with current transmitter licensing requirements. In the
US, to find out the specific details on whether a particular installation is exempt from licensing, please
visit the FCC web site

. 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. Outside the US, contact the responsible telecommunication
authority. The GNC 420W, GNC 420AW, GNS 430W and GNS 430AW owner accepts all responsibility
for obtaining the proper licensing before using the transceiver. The maximum transmitting power,
modulation identification, and frequency band information may be required for licensing and are detailed
in Section 1.4.4.
