500W Series Installation Manual Page 1-1
190-00357-02 Rev. D

1.2 Scope

The installation instructions and other data contained within this manual are FAA approved under
400W/500W Series AML STC SA01933LA, which is applicable for implementation within airplanes
that are type certificated only under Civil Air Regulation 3 (CAR 3) or 14 Code of Federal Regulations
(CFR) Part 23 (only) into which the Garmin 500W Series unit equipment is qualified for installation and
operational approval. Only the equipment and systems interfaces described in this manual have been
determined to be mutually compatible and are operationally suitable and approved for use as
characterized herein, or within the FAA approved airplane flight manual supplement (AFMS) reflecting
main software version 2.00 and later. Some differences in operation may be observed when comparing
the information in this manual and the FAA approved AFMS to later FAA approved software versions.
Such differences will be identified in revised editions of the FAA approved AFMS characterizing later
software versions, and any applicable limitations and normal or abnormal operating conditions.

It is possible for installers and other appropriately certificated persons to seek FAA approval for
installation and operational use of the 500W Series equipment with systems not identified in this manual,
such as for aircraft certificated under 14 CFR parts 25, 27, or 29, by means of a field approval, STC or
TC. Refer to FAA Advisory Circular (AC) 20-138A and other applicable guidance when applying for
installation and operational approval. AC 21-40 provides guidance for the STC approval process and AC
43-210 provides guidance for the field approval process. If the field approval process is used, it is
advisable to consider the conditions and stipulations in FAA Flight Standards Flight Standards
Information Bulletin for Airworthiness (FSAW), 94-32, “Guidance for Performing Field Approvals of
Installation and Operational Use of Global Positioning Systems (GPS) or GPS with Wide Area
Augmentation Systems (GPS/WAAS), Referred to as Global Navigation Satellite Systems (GNSS)
Equipment”, as revised.

Regardless of applicability of the AML STC or alternative application for installation and operational
approval, prior to completing the installation and before returning the airplane to service, the installer or
other appropriately certificated person is required to complete and submit an FAA Form 337 (OMB No.
2120-0020), “Major Repair and Alteration Airframe, Powerplant, Propeller, or Appliance” to their local
FAA Flight Standards District Office describing the work accomplished. The FAA Form 337 must detail
the equipment and systems to which the respective GPS 500W, GNS 530W, or GNS 530AW is
interfaced and reflect appropriately approved or acceptable data for which follow-on FAA field approval
is being sought. See AC 43.9-1E for instructions for completing the FAA Form 337.

1.3 Equipment Description

The 500W Series units are 6.25 inches wide and 4.60 inches 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 TAWS/TERRAIN database (to be inserted in the right
most card slot).

The GPS 500W is a GPS/WAAS unit that meets the requirements of Technical Standard Order (TSO)­C146a (specified in Table 1-4) and may be approved for IFR en route, terminal, non-precision, and
precision approach operations when installed in reference to the instructions in this manual as referenced
in the AML STC SA01933LA.

The GNS 530W includes all the features of the GPS 500W and also includes an airborne VHF
communications transceiver and airborne VOR/localizer (LOC) and glideslope (G/S) receivers. The
“AW” model is a 28 VDC unit with a 16 Watt COM transmitter. The GNS 530W/(AW) meets the
requirements of TSOs specified in Table 1-4.

Page 1-2 500W Series Installation Manual
Rev. D 190-00357-02

The 500W Series unit 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.

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.

1.8 Fault Detection and Exclusion (FDE)

The 500W Series unit, when installed as defined in this manual, complies with the requirements for GPS
primary means navigation in oceanic and remote airspace when used in conjunction with the FDE
Prediction program included with the GNS 400W/500W Series Trainer CD.

The 500W Series unit includes fault detection and exclusion (FDE), which is active for all flight phases
including oceanic and remote operations, en route and terminal, and precision and non-precision
approaches, and does not require any pilot interaction. The FDE consists of two parts:

1. The fault detection function detects a satellite failure that can affect navigation; and

2. The exclusion function is the capability to exclude one or more failed satellites and prevent them

from affecting navigation.

The FDE Prediction program, included with the GNS 400W/500W Series Trainer CD, is used to predict
FDE availability. The FDE Prediction program must be used prior to oceanic or remote area flights for all
operators using the 500W Series unit as primary means navigation under FAR parts 91, 121, 125, and

135.

2. INSTALLATION OVERVIEW

2.1 Introduction

Always follow acceptable avionics installation practices per AC 43.13-1B, AC 43.13-2A, or later FAA
approved revisions of these documents. The GPS/WAAS installation instructions have been prepared to
meet the guidance material contained in AC 20-138A “Airworthiness Approval of Global Navigation
Satellite System (GNSS) Equipment”. The communications installation instructions have been prepared
to meet the guidance material defined by AC 20-67B, “Airborne VHF Communications Equipment
Installations”. Follow the installation procedure in this section, as it is presented, to accomplish a
successful installation. Read the entire section before beginning the work.

Prior to installation, consider the structural integrity of the 500W Series installation as defined in AC

43.13-2A, Chapter 1. Complete an electrical load analysis in accordance with AC 43.13-1B, Chapter 11,
on the aircraft prior to starting modification to ensure aircraft has the ability to carry the 500W Series
load. Refer to Section 3.12 to calculate the total power consumption of each 500W Series mode of
operation. Document the results of the electrical load analysis on the FAA Form 337.

Once the installation is complete, perform the post installation checkout before closing the work area in
case problems occur.
