1.4 LICENSE REQUIREMENTS The following guidance is provided to help ensure the proper licensing of the GNC 420/GNS 430 COM: 1. The Telecommunications Act of 1996 effective February 8, 1996 provides the FCC discretion to eliminate radio station license requirements for aircraft. At present, an individual license to operate the 400 Series aboard a private aircraft is not needed in many circumstances. Please see FCC Fact Sheet PR5000 or contact the FCC at 1-800-322-1117 for more information. 2. N

The FDE function is built into the GPS 400/GNC 420/GNS 430 and does not require pilot interaction. In contrast, the FDE Prediction Program does require pilot interaction and must be used prior to oceanic/remote area flights to predict FDE availability. The 400 Series Trainer software (Garmin Part Number 190-00176-00) includes an FDE Prediction Program to meet the requirements for GPS as a primary means of navigation for oceanic/remote operations per N8110.60. The oceanic flight phase occurs on

2.2.6 ANTENNA LIMITATIONS Garmin’s GA 56 Antennas are recommended for installations where the airspeed of the aircraft is subsonic. In such installations, GA 56—Mod 1 or later—must be used. See the COM, VOR/LOC, and Glideslope antenna specifications for their limitations. 2.2.7 VHF COM INTERFERENCE OF GPS On many panel-mounted installations, VHF COM transceivers can radiate strong harmonics from the transceiver and its antenna. The 400 Series COM does not interfere with its own GPS section. Ho

2.2.8 COM, VOR/LOC, and Glideslope Antenna Installation Instructions Install the COM, VOR/LOC, and Glideslope antennas according to the manufacturer’s recommendations. Avoid running other wires and coaxial cables near the VOR/LOC antenna cable. 2.3 RACK CONSIDERATIONS Plan a location which gives the pilot complete and comfortable access to the entire keypad and which is plainly visible from the pilot’s perspective. Installation of remote switches and annunciators may not be required if the 400
