TCAS I Controls and Displays
18
The CP 66B amber Fail Annunciator will light during self test and in nor-
mal operation will flash if a system failure has been detected. If a failure
has been detected, turning the Power Switch to
OFF
will turn off the
flashing annunciator.
Power Switch:
The
OFF
position deactivates selector switches and
push buttons and extinguishes
FAIL
annunciation if on.
The
SBY
position places the TCAS I in Standby mode.
In Standby mode, surveillance and tracking operations
are disabled and the traffic display is blanked except for a “TCAS STBY”
mode annunciation.
The
ON
position enables the tracking and surveillance operations at the
selected range, display and altitude limit.
Pressing the
TEST
button in the center of the knob initiates a compre-
hensive self test lasting approximately eight seconds. Refer to the
Appendix for a description of the self test function.
Range Knob:
The TCAS I RANGE knob is used to select the range on
the traffic display. The range selections are 3, 5, 10, 15, 20,
and 40. All ranges are in nautical miles.
Note:
This feature may not be available in all installations or this feature
may be superseded by a range control on the traffic display bezel.
Display Select Switch:
The Display Select Switch is used in installations where
the weather radar indicator is the traffic display. It selects
between
T/Wx
(TCAS I w/Weather),
Wx
(Weather Only),
and
TCAS
(Traffic Only) presentations on the radar
screen. Details of the various modes are described later in
this section under Weather Radar Indicators.
Altitude Limit Switch:
The Altitude Limit Select Switch selects altitude display
limits. It has no effect on the TCAS I logic giving TAs.
There are three selections available.
ABOVE
- Traffic that is between 8700 feet above and 2700 feet below
own aircraft will be displayed. Typically ABOVE is used during the climb
phase of flight.
NORM
- Traffic that is between 2700 feet above and 2700 feet below will
be displayed. Typically NORM is used during the en route phase of
flight.
