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 antireflective 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.
