General
Description
RA/VSI No. 2 failure status output to
TCAS processor.
Show the maximum number of
intruder aircraft (0-30) to be shown on
the traffic displays.
Controls if traffic is shown when own
aircraft is on-the-ground. If strapped
to not show traffic on-the-ground,
TCAS goes to STANDBY on-the-
ground.
Shows either all traffic or TA/RA and
near traffic only (for example,
nonthreat traffic not shown).
Puts TCAS into the TA only mode
(sensitivity level 2) and prevents all
audio and aural advisories.
Puts TCAS into the standby mode
(sensitivity level 1) until wind shear
condition is over.
When pushed and released, this
switch cancels active advisory alert
conditions.
Supplies the voice advisory message
alerts to cockpit speaker and optional
headset.
