SECTION 1 - GENERAL (continued)
Class II Oceanic, Remote, and other operations
The Garmin 430W 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 Garmin Prediction Program part number 006-A0154-
03. Oceanic operations are supported when the GNS430W unit annunciates
OCN. This provides an alarm limit of four nautical miles and a mask angle of
five degrees. The GNS430W unit also has the ability to predict RAIM
availability at any waypoint in the database if WAAS corrections are expected
to be absent or disabled. This does not constitute an operational approval for
Oceanic or Remote area operations. Additional equipment installations or
operational approvals may be required.
• Oceanic navigation requires an additional approved long range oceanic
and/or remote area navigation system with independent display, sensors,
antenna, and power source.
• Redundant VHF Com and VHF Nav systems may be required for other than
US 14 CFR Part 91 operations. Check foreign regulation requirements as
applicable.
• Operations approval may be granted for the use of the GNS430W 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.
