MFD Displays
of a + or - followed by two digits
of altitude difference (relative alti-
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
s y m b o l .
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.

During an active RA or TA, a
“TRAFFIC” message will be
annunciated in large text on all
EFS displays configured for dis-
playing TCAS traffic but with
TCAS de-selected. This annun-
ciation will be provided for all nor-
mal operating modes, but not
while maintenance or configura-
tion 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 "TRAF-
FIC" message will be replaced by
a "NO TCAS " message for 15
seconds following a TCAS failure
or a change of TCAS mode to
