TSO LIMITATIONS
A limitation exists pertaining to TSO-C36e (Localizer) and TSO-C34e (Glideslope). The main board
lateral deviation (J4001 Pin 21 MAIN +LEFT and J4001 Pin 22 MAIN +RIGHT) and vertical deviation
(J4001 Pin 27 MAIN +UP and J4001 Pin 28 MAIN +DOWN) outputs exceed the respective TSO MOPS
requirement for current response time due to 120 milliseconds of internal transport delay. Except for this
transport delay, the output characteristics meet the TSO MOPS requirement. Consequently, these outputs
should be used only in applications where the transport delay has been evaluated and found to meet
installation requirements.

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 GNS 530 installation must comply with
current transmitter licensing requirements. To find out the specific details on whether a particular
installation is exempt from licensing, please 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 GNS 530
owner accepts all responsibility for obtaining the proper licensing before using the transponder.
The VHF transmitter in this equipment is guaranteed to meet federal communications
commission acceptance over the operating temperature range.
expressly approved by Garmin could invalidate the license and make it unlawful to
operate the equipment.
1.6
CERTIFICATION
The GPS receivers in the 500 Series units are certified for IFR enroute, terminal, and non-precision
approaches. The 500 Series initial certification was accomplished via STC's by Garmin in a Piper PA32.
See Appendix B for copies of the STC's.
The 500 Series units have been qualified to RTCA/DO-160 Section 22 lightning requirements. Special
installation considerations are required, refer to the Environmental Qualification Forms in Appendix A.
1.7
FAULT DETECTION AND EXCLUSION (FDE)
The 500 Series equipment as installed has been found to comply with the requirements
for GPS primary means of navigation in oceanic and remote airspace, when used in
conjunction with the 500 Series Trainer Program incorporating the FDE Prediction
Program. This does not constitute an operational approval.
The Garmin 500 Series Main and GPS Software version 3.00 and higher incorporate Fault Detection and
Exclusion (FDE) display interface and control, satisfying the requirements for GPS as a Primary Means of
Navigation for Oceanic/Remote Operations per FAA Notice N8110.60.
Fault Detection and Exclusion consists of two parts. The fault detection function detects a satellite failure
that can affect navigation. The exclusion function refers to the capability of excluding one or more failed
satellites and preventing them from affecting navigation.
FDE is provided for Oceanic and Remote Operations, non-precision approaches, en route and terminal
phases of flight. FDE for non-oceanic flight phases adhere to the same missed alert probability, false alert
probability, and failed exclusion probability specified by N8110.60.
