Section 1. GENERAL
1.1 Garmin 400W Series GPS/WAAS Nav Com
The Garmin 400W Series GPS/WAAS Navigator is a panel-mounted
product that contains a GPS/WAAS receiver for GPS approved primary
navigation, under TSO C146a (plus optional VHF Com and VHF Nav
radios) in an integrated unit with a moving map and color display. The 400W
Series unit features a graphical display which may also be used to depict
traffic, weather, or terrain data.
The navigation functions are operated by dedicated keys and graphical
menus which are controlled by the buttons and the dual concentric rotary
knob along the bottom and right side of the display.
Optional VHF Com and VHF Nav radio functions are controlled via
dedicated buttons and knobs on the left side of the display and adjacent to
frequencies they are controlling.

1.2 Operation
GPS/WAAS TSO-C146a Class 3 Operation: The Garmin 400W Series
unit, when installed in accordance with STC SR02232LA, uses GPS and
WAAS (within the coverage of a Space-Based Augmentation System
complying with ICAO Annex 10) for enroute, terminal area, nonprecision approach operations (including “GPS”, “or GPS”, and “RNAV”
approaches), and approach procedures with vertical guidance (including
“LNAV/VNAV” and “LPV”).
Navigation is accomplished using the WGS-84 (NAD-83) coordinate
reference datum. GPS navigation data is based upon use of only the Global
Positioning System (GPS) operated by the United States of America.
1.3 Class II Oceanic, Remote, and other Operations
The Garmin 400W Series, as installed, has been found to comply with the
requirements for GPS primary means of Class II navigation in oceanic and
remote airspace, when used in conjunction with WAAS Garmin Prediction
Program part number 006-A0154-03. Oceanic operations are supported
when the 400W Series unit annunciates OCN. This provides an alarm limit
of four NMI and a mask angle of five degrees. The 400W series unit also has
the ability to predict RAIM availability at any waypoint in the database or if
WAAS corrections are expected to be absent or disabled. This RFMS does
not constitute an operational approval for Oceanic or Remote area
operations. Additional equipment installations or operational approvals may
be required.
a) Oceanic navigation requires an additional approved long range oceanic
and/or remote area navigation system with independent display, sensors,
antenna, and power source. (It may be a second 400W/500W Series unit.)
b) Redundant VHF Com and VHF Nav systems may be required for other
than U.S. 14 CFR Part 91 operations. Check foreign regulation
requirements as applicable. (It may be a second 400W/500W Series unit.)
c) Operations approval
may be granted for the use of the 400W Series unit
RAIM prediction function in lieu of the Prediction Program for operators
requiring this capability. Refer to your appropriate civil aviation
authorities for these authorizations.

Section 2. LIMITATIONS
2.1 Pilot’s Guide
The GARMIN 400W Series Pilot’s Guide, part number and revision listed
below (or later revisions), must be immediately available for the flight crew
whenever navigation is predicated on the use of the 400W Series unit.
y 400W Series Pilot’s Guide & Reference P/N 190-00356-00 Rev C
y 400W/500W Series Optional Displays P/N 190-00356-30 Rev C
y 400W/500W Series Display Interfaces P/N 190-00356-31 Rev C
This RFM supplement does not grant approval for IFR operations to
rotorcraft limited to VFR operations. Additional rotorcraft systems may be
required for IFR operational approval. Systems limited to VFR shall be
placarded in close proximity to the 400W Series unit
“GPS LIMITED TO VFR USE ONLY”.
2.2 System Software:
The system must utilize the Main and GPS software versions listed below (or
later FAA approved versions for this STC). The software versions are
displayed on the self-test page immediately after turn-on for approximately 5
seconds or they can be accessed in the AUX pages.
Subsequent software versions may support different functions. Check the
400W Series Pilot’s Guide for further information.
