Hazard Awareness
Ryan TCAD 9900BX with GDL 88
Ryan TCAD is a system that provides audio and visual alerts for traffic near your
aircraft. The information from this system can be interfaced through GTN Xi.
TRAFFIC DISPLAY RANGE
Options include: • 1 nm • 2 nm • 2 and 6 nm • 6 and 12 nm • 12 and 24 nm
RYAN TCAD ALERT TYPES
The Ryan TCAD on-board air traffic display identifies potential collision threats. It
computes the relative altitude and range of threats from nearby Mode C and
Mode S-equipped aircraft. TCAD will not detect aircraft that are not equipped with
operating transponders or that are beyond radar coverage. When within the defined
limits, TCAD creates a
shield
of airspace around the aircraft that detected traffic
cannot penetrate without triggering an alert.
•
TA:
Traffic Advisory. Traffic with 500 feet, or less, of altitude separation that
is converging or maintaining altitude separation.
•
PA: Proximity Advisory. Traffic with 500 feet of altitude separation that is not
a TA.
•
TRFC:
Other traffic.
