CAS/Part No.9005000
is similar to that on combined RA/TA VSI indicators. Traffic symbology is identical to that
displayed on the RA/TA VSI.
(2) Some manufactures’ displays may indicate Other Traffic with a hollow WHITE diamond.
Some training materials may refer to the color BLUE as CYAN.
(a) Colors
1 Amber
Represents a moderate threat to a TCAS-equipped aircraft. A visual
search is recommended to prepare for intruder avoidance. Amber is
used only in conjunction with a traffic advisory.
2 Red
Represents an immediate threat to a TCAS-equipped aircraft.
Prompt action is required to avoid the intruder. This color is only
used in conjunction with a resolution advisory.
3 Blue
Represents proximate traffic and other traffic the TCAS surveillance
logic has in its track file.
4 White
Used only for mode annunciations and for reference graphics,
including aircraft home position, range ring, and VSI scale.
(b) Traffic Identification
1 Traffic Advisory
Intruder aircraft entering the caution area, 20 to 48 seconds from the
TCAS 2000 collision area are represented as a solid amber circle.
This type of traffic results in a traffic advisory.
2 Resolution Advisory
Intruder aircraft entering the warning area, 15 to 35 seconds from the
TCAS 2000 collision area are represented as a solid red square.
This type of traffic results in a resolution advisory.
3 Proximate Traffic
Aircraft within 6.0 nautical miles and ±1200 feet (365.76 meters)
vertically are represented as a solid cyan diamond. Proximate traffic
is shown to improve situational awareness in the event of a potential
conflict with higher priority RA or TA aircraft.
4 Other Traffic
Any transponder replying to traffic not classified as an intruder or
proximate traffic, and within ±2700 feet (822.96 meters) vertically
and the range of the display are represented as hollow cyan
diamonds (only in view with the traffic switch ON and no TA or RA in
process). The predicted flightpaths of proximate and other traffic do
not penetrate the collision area of the TCAS aircraft.
