− Pilots are authorized to deviate from their current Air Traffic Control
(ATC) clearance to the extent necessary to comply with an EGPWS
warning.
− The Terrain Display is intended to be used as a situational tool only
and may not provide the accuracy and/or fidelity on which to solely
base terrain avoidance maneuvering.
− In the event that accuracy of the airplane position data from the
FMS becomes inadequate for navigation (Dead Reckoning Mode),
the Terrain Awareness Alerting and Display functions must be
inhibited. This will not affect the basic GPWS functions (modes 1 to
7). If the FMS is restored after a period of inadequacy, the Terrain
Awareness may be enabled by pressing again the TERRAIN SYS
OVRD button.
− In case of a conflict between the terrain alerts and an auto-popped-
up picture, pilots must check the sweeping marker movement on
the horizontal line below the terrain picture. If the marker is frozen,
the MFD terrain indication must be deselected on MFD bezel panel.
− For airplanes Post-Mod. SB 145-31-0009 or S/N 145.118 and on, in
case of a conflict between the terrain alerts and an auto-popped-up
picture, pilots must check the MFD 2 terrain information. If the
terrain picture bus fail is not annunciated (TERR amber
annunciation), the MFD 2 must be used as terrain picture
reference.
