6.7 L-3 SkYWATCH (SkY497) TAS (OPTIONAL)
WARNING: The Traffic Advisory System (TAS) is intended for advisory use only. TAS is intended to help the
pilot locate traffic visually. It is the responsibility of the pilot to see and maneuver to avoid traffic.
NOTE: TIS is disabled when the Traffic Advisory System (TAS) is installed.
NOTE: Refer to the SKYWATCH® (SKY497) Pilot’s Guide for a detailed discussion of the SKY497 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 the Mode S transponder for the air-to-air traffic data link. Traffic is
displayed according to TCAS symbology using four different symbols.
TAS Symbol Description
Non-Threat Traffic
Proximity Advisory (PA)
Traffic Advisory (TA)
Traffic Advisory Off Scale
Table 6-20 TAS 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.
OPERATION
The unit must be in operating mode for traffic to be displayed. The ability to switch from standby to operating
mode on the ground is especially useful for scanning the airspace around the airport before takeoff.
