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 TAS in Standby mode. In
Standby mode, surveillance and tracking operations
are disabled and the traffic display is blanked except for a “TAS STBY”
(“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 TAS 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may be superseded by a range control on the traffic display bezel.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 (TAS 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 TAS 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.
