(3) TRAFFIC ADVISORY (TA) TRAFFIC — A symbol
change to a filled amber circle indicates that the intrud-
ing aircraft is considered to be potentially hazardous.
Depending on your own altitude, TCAS II will display
a TA when time to the closest point of approach (CPA)
is between 20 and 48 seconds. An advisory voice mes-
sage "TRAFFIC, TRAFFIC" may be heard through the
audio system.
(4) RESOLUTION ADVISORY (RA) (TCAS II only) — A
solid red square indicates that the intruding aircraft is
projected to be a collision threat. TCAS II calculates
that the intruder has reached a point where a resolu-
tion advisory is necessary. The time to closest approach
with the intruder is now between 15 and 35 seconds,
depending on your altitude. The symbol appears with
an audio warning and a vertical maneuver indication
on the PFD VSI.
ENHANCED GROUND PROXIMITY WARNING SYSTEM (EGPWS)
EGPWS is shown on the MFD by pushing the EGPWS menu button on
the MFD main menu. When TERRAIN is selected for display, the
EGPWS sends the terrain data directly to the MFD display unit via the
WX picture bus and replaces the WX display with terrain information.
If a potential terrain hazard is sensed by the EGPWS, terrain data auto-
matically pops up on the MAP. This "pop-up" mode defaults to the
10 NM range. EGPWS annunciators are described in the table below
and are displayed in the upper left corner of the MFD.

The terrain data is displayed above the airplane symbol on the MFD in
green, yellow, and red colors that define the elevation of the terrain rel-
ative to the airplane's current altitude. Terrain that is more than 2000
feet below the airplane is not included in the display.
A moving marker scrolls across the bottom of the EGPWS display as an
indication that the terrain is display is operational.
