TCAS ONLY MODE
In this mode the screen’s origin point is 1/3 up from the bottom of the
screen. Only TCAS information is displayed. This mode is main-
tained unless another mode is manually selected. The range dis-
played is controlled by the TCAS control panel. A 2 nm range ring is
displayed on ranges 3, 5, 10, and 15 nm. The 2 nm range ring con-
sists of discrete dots (cyan) at each of the 12 clock positions. The 2
nm range ring is not displayed on ranges 20 and 40 nm; instead a
half-range ring is displayed. The half-range ring consists of discrete
dashes (cyan). The TCAS operational mode is annunciated in the
lower left hand corner of the screen.
Options to these displays can exist. Example: the 10 and 15 nm
ranges could have 2 nm and 5 nm range rings. The 40 nm range
could have 2, 5, and 20 nm range rings. The outer range might also
have cardinal heading identification. These options are dependent on
the part number of the GC 362 used.
Note: On the “TCAS ONLY” display, “WX ON” will be annunciated
in the upper right hand corner if the weather radar is transmitting.
See Weather Radar operating guide.
At power-up the screen initially displays the Radar with TCAS
Overlay mode. When the Test mode is selected on the
Mode S/TCAS control panel the self-test pattern is displayed unless
TCAS system failures are detected. If system failures are detected
the screen is blanked and a list of faults is displayed.
