TCAS I Theory of Operation and Symbology
No altitude number or trend arrow will appear beside any Intruder that is
Non-Altitude Reporting (NAR).
If TCAS I direction finding techniques fail to locate the azimuth of another
aircraft, a NO BEARING message appears on the screen when the
Intruder becomes a Traffic Advisory.
NON-THREAT TRAFFIC
An open white diamond indicates that an Intruder’s rela-
tive altitude is greater than ±1200 feet, or its distance is
beyond 5 nm range. It is not yet considered a threat.
This traffic is 1700 feet above your own altitude,
descending at 500 feet per minute or greater.
PROXIMITY INTRUDER TRAFFIC
A filled white diamond indicates that the Intruding air-
craft is within ±1200 feet and within 5 nm range, but is
still not considered a threat.
This Intruder is now 1000 feet above your aircraft and
descending at 500 fpm or greater.
