Description
AGL altitude data to TCAS processor
from analog radio altimeter No. 1.
Radio altimeter No. 1 failure status
input to TCAS processor.
AGL altitude data to TCAS processor
from analog radio altimeter No. 2.
Radio altitude No. 2 failure status
input to TCAS processor.
ARINC 429 data from digital radio
altimeter No. 1 to TCAS processor.
ARINC 429 data from digital radio
altimeter No. 2 to TCAS processor.
Specify the type of analog radio
altimeter that is connected to the
Analog Radio Altitude No. 1 and No. 2
input (for example, King, Sperry,
Collins, ARINC 552A, etc.).
Tells TCAS processor if one or two
radio altimeters are installed.
Tells TCAS processor that after
considering own altitude, attitude,
cargo weight factors, etc. a
performance management computer
has found if it is possible or not
possible for own aircraft to climb at a
rate of 1500 feet for each minute.
Digital equivalent of climb
performance discrete from a
performance management computer.
