Operation

GPS/WAAS TSO-C146a Class 3 Operation: The Garmin 400W Series
unit, when installed in accordance with STC SA01933LA-D, uses GPS
and WAAS (within the coverage of a Space-Based Augmentation System
complying with ICAO Annex 10) for enroute, terminal area, non-
precision approach operations (including "GPS", "or GPS", "RNAV",
"LNAV", and "LP" 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.

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 AFMS 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.
