General
Description
For adjusting synthesized voice
output of the TCAS processor when
the aircraft is airborne.
For adjusting synthesizer voice output
of the TCAS processor when aircraft
is on the ground.
Supply TA and RA alert output that
start optional tone generators found
externally in the aircraft.
When strapped, supplies interval of
voice output 1 second to aural
advisory output. When open, drives
aural advisory discrete output.
Supply TA and RA alert output that
start serviceable lamp indicators
found externally in the aircraft.
Determines if own aircraft is below
1750 feet (radio altitude), intruders
found to be ON GROUND will be
shown.
Finds if RA display status is in
operation or prevented.
