• Synthetic Vision (Optional)
The synthetic vision presentation must not be used as the sole reference for
aircraft control (without reference to the primary flight instruments).
The synthetic vision presentation must not be used as the sole reference for
navigation or obstacle/terrain/traffic avoidance.
If the installed TAWS or Terrain Alerting system is inoperative, the synthetic
vision display on the PFD must be selected off.
Terrain/TAWS alerts must be inhibited when landing at an airport that is not in
the airport database.
Refer to section 7.7.5.1 for information on how to enable the optional Synthetic
Vision.
• Terrain warning and avoidance system (Optional)
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.
Refer to section 7.7.5.1 for information on how to enable the optional TAWS.
NOTE
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.
