Ryan TCAD Description
NOTE
: Refer to the Ryan TCAD Pilot’s Guide for a detailed description of
the Ryan TCAD System.
The Ryan TCAD (Traffic and Collision Alert Device) is an on-board air traffic
display used to identify potential collision threats. TCAD computes relative altitude
and range of threats from nearby Mode C and Mode S-equipped aircraft. TCAD
will not detect aircraft without operating transponders or those that are beyond
radar coverage. TCAD, within defined limits, creates a “shield” of airspace around
the aircraft that detected traffic cannot penetrate without triggering an alert.
TA:
Traffic Advisory. This is traffic with 500 feet, or less, of altitude separation
that is converging or maintaining altitude separation.
PA:
Proximity Advisory. This is traffic with 500 feet of altitude separation that
is not a TA.
TRFC:
Other traffic.
