TA/RA (Traffic Advisory and Resolution Advisory) mode. Activates
the Mode S transponder, altitude reporting, and TCAS “TA/RA”
mode. Aural and visual RAs (Resolution Advisories) will be issued for
traffic determined to be a threat. Traffic will be presented on the traffic
(TA) display. TA/RA mode is annunciated in the display window, on
the optional color radar indicator or dedicated traffic display.
The inner knob selects the traffic display range in nm (nautical miles).
This knob can select 3, 5, 10, 15, 20 or 40 nm range on the TCAS
traffic display. The range is displayed in the display window during
range selection.
Note: The Range knob is continuous rotary and does not roll over or stop.
The traffic display may have another range select source. The select-
ed TCAS range is always annunciated on the traffic display. The
range annunciated is the maximum displayed range to the front of the
aircraft. The range to the rear is either full annunciated range or 1/2
the annunciated range, depending on the display. The selected range
has no effect on the TCAS logic giving TAs or RAs.
When the inner knob is pushed, the Traffic Advisory altitude
(Above/Norm/Below) display limits are sequentially selected. There
are three display levels to choose from.
ABOVE; 8700 feet above (9000 Change 7 or later) and 2700 feet
below, is typically used during the climb phase of flight. A "^" (carat)
will be annunciated in the display window.
NORMAL; 2700 feet above and 2700 feet below, is used during the
enroute phase of flight. Both the "^" and "v" (carats) will be annunci-
ated in the display window.
BELOW; 2700 feet above and 8700 feet below (9000 Change 7 or
later), is used during the descent phase of flight. A "v" (carat) will be
annunciated in the display window.
The Above/Below selection has no effect on the TCAS logic giving
TAs and RAs.
