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 traf-
fic display used to identify potential collision threats. TCAD computes rela-
tive 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.
