(4) Post
Flight.
The
recommended
procedure is to place the TCAS in STBY mode as
soon as practical after a landing is completed.
p. Alternate Operating Procedures. The
following
are
suggested
alternate
operating
procedures for use in event a TCAS flag is displayed
on the vertical speed indicator or the FAIL indicator on
the transponder/TCAS control panel is lit. RA's cannot
be displayed so the RA flag will also be displayed.
(1) V/S and RA Flags Displayed.
1. Select TA ONLY.
2. Traffic display will provide information,
including TA's relative to intruders in
your area.
Do not maneuver the aircraft solely with
reference to information on the traffic
display.
(2) RA Flag Displayed. Appearance of this
flag on the vertical speed indicator indicates failure of
the RA functions of the TCAS. Follow the same
procedure as in (1) above.
(3) TCAS Flag Displayed. Appearance of
this flag indicates failure of some part of the TCAS
system. This includes the associated display systems,
as well as the units, generating the major TCAS
functions and signals.
1. Verify that ATC FAIL indicator is not
lit. If lit, refer to ATC FAIL indicator
procedures. If not, continue with the
following procedures.
2. Select TA ONLY.
Do not maneuver the aircraft solely with
reference to information on the traffic
display.
3. If TCAS flag is replaced by a TA
ONLY
message,
continue
TCAS
operation in TA mode.
4. If TCAS FAIL flag remains, select
XPDR or STBY, as TCAS is no longer
available.
