TRAFFIC DISPLAYS
TCAS traffic can be displayed on a
variety of instruments or indicators.
The following describes the various
TCAS traffic displays.
The (IVA 81A/C/D) TA/VSI displays
combine the vertical speed instru-
ment with the Traffic display functions
on an LCD screen. A pointer indi-
cates the aircraft’s VS (vertical
speed) against the scale around the
circumference of the circle. A VSI
flag, which would be shown in the
lower right-hand corner, will cause
the VS pointer to disappear if a VS
source failure is detected. The traffic
location is presented on the face of the display inside the vertical speed
scale.
Note: “RA FAIL” may annunciate during system start up prior to air
data coming on line or if air data fails. (“RA FAIL” is not a required flag
for TCAS I)
The TID 66A/D is a dedicated TCAS
traffic display similar to the TA/VSI
without any vertical speed functions.
The bearing and distance of Intruder
aircraft are relative to the own-aircraft
symbol. The own-aircraft symbol is
located a third up from the bottom of
the screen.
The full scale display range directly
ahead of the aircraft is annunciated in
the upper right-hand corner. The dis-
tance aft is one-half the annunciated
range. The distance to the sides of
the aircraft (at 90° and 270°) is two-
thirds the annunciated range. A 2 nm
circle indicated by blue dots every 30° is present at every range except
40 nm.
The lower right-hand corner of the TID 66A/D annunciates the
Above/Below and FL display formats. The FL feature is inhibited below
18,000 feet MSL unless barometric corrected altitude is available from
an air data source. If FL is selected while inhibited, “FL - - -” is annun-
