NOTE: The TCAS processor reduces range tracking in high density areas to reduce the number of
receptions to be processed by TCAS and for interference limiting.

CAS-100 COLLISION AVOIDANCE SYSTEM
MTL + 13 dB
300 nsec
0.5 µsec
0.050 µsec
The shape and dimension of the range tracking volume is
dependent on:
• the Mode S or ATCRBS transponders are being
interrogated
• tracking is occurring on a directional or omni antenna
• attenuation levels applied to the transmitted pulses from
the TCAS processor transmitter. NOTE
TCAS II tracks other transponder-equipped aircraft that are
in a relative range of ± 10,000 feet.
Minimum of 60 tracks. The 30 closest intruders go to
Collision Avoidance Algorithms.
Minimum of 150 addresses of defected Mode S equipped
aircraft.
Resolution advisory within 1.5 seconds after threat intruder is
detected.
4 Watts into 8 ohms (pin programmable to lower output)
40 mW into 600 ohms (pin programmable to lower output)
