1.3 Navigation Database

The 500W Series unit database cards must be installed. The software
automatically precludes invalid databases for use by the 500W. Database cycle
information is displayed at power up on the screen, but more detailed
information is available on the AUX – UTILITY page.

a) Installations with dual 400W/500W Series units will only crossfill between

units when they contain the same database cycle. Updating of each database
must be accomplished on the ground prior to flight.

1.4 Terrain Database

The 500W Series unit supports Terrain Proximity or HTAWS and requires a
Terrain database card to be installed in order for the function to operate.
Database cycle information is displayed at power up on the screen, but more
detailed information is available on the AUX – UTILITY page. Terrain
database cards contain the following data:

a) Due to the terrain resolution used in this system, the terrain database is

divided into six regions [Americas North; Americas South; Atlantic North;
Atlantic South; Pacific North; Pacific South]. Use of the proper database
region must be verified by the pilot.

b) The Obstacle Database has an area of coverage that includes the United

States and Europe, and is updated as frequently as every 56 days.

NOTE:

The area of coverage may be modified as additional terrain data sources
become available.

1.5 Navigation

No navigation is authorized north of 89° (degrees) north latitude or south of 89°
(degrees) south latitude.

1.6 Terrain Proximity Display [All Units]

Terrain Proximity is the display of terrain information and comprises of a 2-D
picture of the surrounding terrain and obstacles relative to the position and
altitude of the rotorcraft, however it does not provide any alerts.

Navigation must not be predicated upon the use of the terrain display. The
terrain display is intended to serve as a situational awareness tool only. By
itself, it may not provide either the accuracy or the fidelity on which to base
decisions and plan maneuvers to avoid terrain or obstacles.

Terrain may not be depicted on the terrain display within 1nm of airports and
heliports, however terrain hazards may exist in these areas.

1.7 HTAWS Function [Units with HTAWS]
HTAWS shall NOT be used for navigation purposes.

HTAWS shall only be inhibited when in visual contact with terrain and when
the pilot can be assured of maintaining clearance from terrain and obstacles.

RP Mode shall only be used when in visual contact with terrain.
