1. GENERAL DESCRIPTION
1.1 INTRODUCTION
This manual describes the physical, mechanical, and electrical characteristics and the installation
requirements for the 500 Series (GPS 500 and GNS 530) panel-mounted units. After installation of the
500 Series system, FAA Form 337 must be completed by an appropriately certificated agency to return the
aircraft to service.
Note: Throughout this document references made to GNS 530 shall equally apply to the GNS 530A
except where specifically noted. References made to the GPS 500 and GNS 530 apply equally to the
GPS 500 w/TAWS and the GNS 530 w/TAWS except where specifically noted.
1.2 EQUIPMENT DESCRIPTION
The 500 Series units are mark width (6.25” wide) units, and 4.60” high. The display is a 320 by 234 pixel
color LCD. The units include two removable data cards, one with a Jeppesen database (to be inserted in
the left most card slot), and the second being a Terrain database (to be inserted in the right most card slot).
The GPS 500 is a GPS receiver certifiable for IFR en route, terminal, and non-precision approach
operations.
The GNS 530 includes all the features of the GPS 500, and also includes IFR certified airborne VHF
communications transceiver and an IFR certified airborne VOR/Localizer and Glideslope receivers. The
(A) model is a 28 Vdc unit with a 16 Watt COM transmitter. Both units are TAWS or TERRAIN
upgradeable.
GPS signals are received by Garmin's low profile GA 56 antenna (P/N 010-10040-0X).
CAUTION
The 500 Series product lens is coated with a special anti-reflective coating which is very
sensitive to skin oils, waxes and abrasive cleaners. CLEANERS CONTAINING
AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It is very important
to clean the lens using an eyeglass lens cleaner, which is specified as safe for anti-
reflective coatings and a clean, lint-free cloth.
CAUTION
The use of ground-based cellular telephones while aircraft are airborne is prohibited by
FCC rules. Due to potential interference with onboard systems, the use of ground-based
cell phones while the aircraft is on the ground is subject to FAA regulation 14 CFR
§91.21.
FCC regulation 47 CFR §22.925 prohibits airborne operation of ground-based cellular
telephones installed in or carried aboard aircraft. Ground-based cellular telephones must
not be operated while aircraft are off the ground. When any aircraft leaves the ground,
all ground-based cellular telephones on board that aircraft must be turned off.
Ground-based cell phones that are on, even in a monitoring state, can disrupt GPS
performance.

1.4 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.
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 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.
CAUTION
The VHF transmitter in this equipment is guaranteed to meet federal communications
commission acceptance over the operating temperature range. Modifications not
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)
NOTE
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.

Page 1-8 500 SERIES INSTALLATION MANUAL
Rev S 190-00181-02
The FDE function is built into the GPS 500/GNS 530 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 500 Series Trainer software 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 the GPS 500/GNS 530 when more than 200 nautical miles from the nearest airport.
All operators using the GPS 500/GNS 530 as primary means of navigation in oceanic/remote areas under
FAR parts 91, 121, 125 and 135 must utilize the FDE Prediction Program prior to conducting a flight in
these areas.
