HAZARD AVOIDANCE
6.7 L-3 SKYWATCH TRAFFIC
WARNING: Do not rely solely upon the display of traffic information to accurately depict all of the traffic
information within range of the aircraft. Due to lack of equipment, poor signal reception, and/or inaccurate
information from other aircraft, traffic may be present but not represented on the displays.
NOTE: TIS is disabled when a TAS or Traffic Collision Avoidance System (TCAS) is installed.
NOTE: Refer to the SKYWATCH

(SKY497/SKY899) Pilot’s Guide for a detailed discussion of the TAS.
TAS SYMBOLOGY
The optional Traffic Advisory System (TAS) is designed to help in detection and avoidance of other aircraft. TAS
uses an on-board interrogator-processor and an altitude reporting transponder for the air-to-air traffic data link.
Traffic is displayed using the symbology shown in Table 6-16.
Traffic Symbol Description
Non-Threat Traffic
Proximity Advisory (PA)
Traffic Advisory (TA)
Traffic Advisory Off Scale
Table 6-16 Traffic Symbol Description
A Non-threat Advisory, shown as an open white diamond, indicates that an intruding aircraft is at greater than
±1200 feet relative altitude or the distance is beyond 5 nm.
A Proximity Advisory indicates that the intruding aircraft is within ±1200 feet and is within 5 nm range, but
is still not considered a threat.
A Traffic Advisory (TA) alerts the crew to a potentially hazardous intruding aircraft. Closing rate, distance,
and vertical separation meet TA criteria. A Traffic Advisory that is beyond the selected display range is indicated
by a half TA symbol at the edge of the screen at the relative bearing of the intruder.
