The Air/Ground Discrete Input for the Air/Ground relay.
The normal failure mode is the airborne condition.
The following applies:
RMP5K RTP5J
1 1 a/c on ground, don't inhibit ATCRBS replies
1 0 a/c on ground, don't inhibit ATCRBS replies
0 1 a/c on ground, inhibit ATCRBS replies
0 1 a/c airborne, don't inhibit ATCRBS replies
Where 0 = Open
1 = Ground
The performance limit shows to TCAS when the
aircraft can no longer get a 1500 feet per minute climb.
When the input is GROUND the performance is not
limited. When the input is OPEN the climb is limited if
the altitude of the aircraft is above the value set by the
Altitude Limit Program (See below).
Limit Input RMP6D Relative Altitude
Yes Open Below
Yes Open Above
No Gnd Below
No Gnd Above
The TA Display Status input are connected to their
related Traffic Display Status output (valid).
If any of the Display Status discretes are not
necessary they must be attached to ground as
necessary for the installation.
The RA Display 1 and 2 Status discretes indicate the
validity of the resolution displays. They are connected
to their respective RA Display Status output (valid).
This pin shows the position of the landing gear. The
usual mode is the RETRACTED position.
Where 0 = Gear Retracted = Open
1 = Gear Extended = Ground
