TAS Theory of Operation and Symbology
SL B In sensitivity level B, TAS performs surveillance and tracking func-
tions and provides traffic advisories. The conditions for sensitivity
level B are based on own aircraft in-flight and:
(1) If radio altitude source is installed and own aircraft altitude is
above 2,000 feet AGL (radio altitude).
(2) If radio altitude source is NOT installed and own aircraft has
Landing Gear Retracted.
(3) If the aircraft has a fixed landing gear and no radio altimeter is
installed.

CONDITIONS FOR TRAFFIC ADVISORIES (TAs)
SL A The following conditions cause TAS to generate a TA in sensitivity
level A:
• TAS calculates that if current closing rate is maintained, separa-
tion of less than 600 feet in altitude between own and Intruder will
occur in 20 seconds.
• Separation between own and Intruder is less than 600 feet in alti-
tude and less than 0.20 nautical mile range.
• NAR (Non-Altitude Reporting) Intruder is within 15 seconds or
0.20 nautical mile range.
SL B The following conditions cause TAS to generate a TA in sensitivity
level B:
• TAS calculates that if current closing rate is maintained, separation
of less than 800 feet in altitude between own and Intruder will
occur in 30 seconds.
• Separation between own and Intruder is less than 800 feet in alti-
tude and less than 0.55 nautical miles in range.
• NAR (Non-Altitude Reporting) Intruder is within 20 seconds or
0.55 nautical mile range.
Standby
or Fail
• TAs are not generated.
