not required to do so. See section 4.5 of this manual to determine if this
capability is supported in this installation.

2.14 Terrain Proximity Function (All Units)

Terrain, point obstacle, and wire obstacle information appears on the map and
terrain display pages as red and amber terrain, obstacles, or wires and is depicted
for advisory use only. Aircraft maneuvers and navigation must not be predicated
upon the use of the terrain display. Terrain, obstacle and wire information is
advisory only and is not equivalent to warnings provided by TAWS.
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 and TAWS are separate features and mutually
exclusive. If "TAWS B" is shown on the bottom right of the
dedicated terrain page, then TAWS is installed.

2.15 TAWS Function (Optional)

Flight crews are authorized to deviate from their current ATC clearance to the
extent necessary to comply with TAWS warnings. Navigation must not be
predicated upon the use of TAWS.
TAWS shall be inhibited when landing at an airport that is not included in the
airport database.
If an external TAWS annunciator panel is installed in the aircraft, this
annunciator panel must be fully functional in order to use the TAWS system.
Terrain and TAWS are separate features and mutually
exclusive. If "TAWS B" is shown on the bottom right of the
dedicated terrain page, then TAWS is installed.
