C. System Component Description and Functions
(1) MILACAS-FR Processor
(a) General
The microprocessor based MILACAS-FR Processor is the master control unit in
the system. It consists of a combined computerized control system and L-band
receiver/transmitter. Operation of the TCAS system is controlled by TCAS
software resident in the computer control memory.

(b) MILACAS-FR Processor Description and Basic Functions
The MILACAS-FR Processor routinely reads and stores the own aircraft
information that follows:
information that follows:
1
Own aircraft heading, pitch, roll, and radio altimeter inputs. This information,
in conjunction with own pressure altitude data, allows TCAS to determine own
aircraft position and flight path for use during tracking, RA and TA advisories,
and traffic display computations.

2
Own aircraft pressure altitude data received on the ARINC 429 data bus from
the Mode S transponder. Pressure altitude is input to the transponder from
own aircraft pressure altitude source. Pressure altitude is used to calculate
own aircraft altitude relative to the intruder altitude and own aircraft flight level
altitudes.

3
Mode control requests and traffic display control inputs from the Mode S
transponder on the ARINC 429 data bus. The Mode S transponder receives
data from the transponder control panel (and may in the future also receive
control inputs from ground stations). This information is a factor in TCAS
sensitivity level calculations and traffic display formats.

Own aircraft identification code (transponder I.D.) received on the ARINC 429
data bus from own Mode S transponder. Own aircraft identification is input to
the transponder by 24 discrete bit strapped inputs. Own aircraft I.D. is used
by the MILACAS-FR Processor during air-to-air coordination routines.

Own aircraft maximum airspeed data received on the ARINC 429 data bus
from own Mode S transponder. Own aircraft maximum airspeed is input to the
transponder by three discrete bit strapped inputs. This information is used in
maximum closing rate projections and RA computations.

Antenna delay strap inputs. These 3 discrete inputs are used during TCAS
range computations to compensate for cable delay differences between the
top and bottom antennas.
