ADS-B Traffic Advisory System (ATAS)
The ADS-B Trafc Advisory System (ATAS) alerts the ight crew to
nearby aircraft and assists the pilot in the visual acquisition of aircraft
that may represent a danger. The following information provides details
on operation of ATAS and the criteria for issuing a Trafc Advisory (TA).
• The tracking of other aircraft is in a cylindrical volume centered
on own aircraft with a maximum radius of 20 nmi and extending
10,000 ft above and 10,000 ft below ownship.
• ATAS will track up to 60 intruders simultaneously.
• When ownship is in the airport environment, a Trafc Advisory
(TA) is displayed 12.5 to 35 seconds prior to the CPA with another
aircraft when the CPA is within 750 ft horizontally and 300 ft
vertically.
• A TA symbol remains on the screen for at least 8 seconds unless
the respective track is terminated.
• A TA is displayed only when the ownship aircraft status is in air.
• Aircraft that are within a range of 6 nmi of ownship with a vertical
distance of +/- 1200 ft (if altitude is reporting) are classied as a
Proximate Advisory (PA). A PA is displayed only for aircraft that
are in air.
TRAFFIC ADVISORY SYSTEMS
The Lynx NGT-9000 has two trafc advisory systems available.
• The Trafc Advisory System (TAS) option requires a specic model
of the Lynx NGT-9000. TAS is an active system that interrogates
nearby aircraft transponders.
• The ADS-B Traffic Advisory System (ATAS) option provides
trafc alerts using ADS-B In (ADS-B, ADS-R, and TIS-B) trafc
information. This feature is available for Release 2.0 or greater.
Both systems alert the ight crew of trafc advisories aurally and
visually which assists the pilot in the visual acquisition of aircraft that
may represent a danger. ATAS and TAS may operate at the same time
with trafc information being correlated by the unit.
