Description
Traffic display and resolution advisory
data from TCAS processor to TA/VSI or
RA/VSI No. 1 or No. 2. (The RA/VSI
uses only that data for resolution
advisories.)
Supplies TA/VSI or RA/VSI No. 1 or No.
2 failure status to TCAS processor.
Pressure altitude from an aircraft static
pressure port.
Analog altitude rate which is converted
by the TA/VSI or RA/VSI into vertical
speed pointer position on the VSI.
Same as above.
Digital vertical speed related data which
is converted by the TA/VSI or RA/VSI
into vertical speed pointer position on
the VSI.
Same as above.
