tude) in hundreds of feet
between the intruder and own
aircraft. (+ = intruder above own
aircraft) During selection of actu-
al altitude, and with a valid
source of own altitude provided
by the TCAS processor, the data
tag will consist of three digits rep-
resenting hundreds of feet above
MSL. Actual altitudes below sea
level will be displayed as two dig-
its preceded by a minus sign.
The data tag will be centered on
the intruder symbol and posi-
tioned above it when the intruder
is above own aircraft. The data
tag will be positioned below the
intruder symbol when the intruder
is below own aircraft. The rela-
tive altitude data tag for intruders
at the same altitude as own air-
craft will consist of “00” without a
+ or - sign and be positioned to
indicate the intruder’s most
recent altitude deviation from
own aircraft. When no altitude
trend information is available, the
“00” is positioned below the traffic
symbol.
Off-Scale Traffic
RA and TA traffic that is located
beyond the selected range of a
TCAS display will be shown as
one half of the appropriate intrud-
er symbol located on the outer
edge of the displayed area at the
proper bearing. A data tag
and/or vertical speed arrow asso-
ciated with this intruder will retain
its normal position relative to the
intruder symbol and only that
portion (if any) within the normal
display area will be visible.

ANNUNCIATIONS
Traffic
During an active RA or TA, a
“TRAFFIC” message will be
annunciated in large text on the
MFD and EHSI. The “TRAFFIC”
message will not be displayed on
the MFD if the MFD is in TCAS
ONLY format. This annunciation
will be provided for all normal
operating modes, but not while
maintenance or configuration
pages are displayed. “TRAFFIC”
will be red during an active RA
and yellow during an active TA
(an RA has priority over a TA).
This annunciation will not be
made while TCAS is selected for
display. Beginning with software
0802,the “TRAFFIC” mesage will
be replaced by a "NO TCAS"
message for 15 seconds follow-
ing a TCAS failure or a change of
TCAS mode to Standby.
NOTE: In some installations a
remote annunciator may be
installed to provide full time
TCAS operational status.
TCAS
TCAS ONLY format will include a
cyan “TCAS” displayed in the
vertical field where the selected
navigation source is normally dis-
played in other modes.
