ADS-B Traffic Advisory System (ATAS)
The ADS-B Trafc 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 Trafc 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 Trafc 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 classied 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 trafc advisory systems available.
• The Trafc Advisory System (TAS) option requires a specic 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
trafc alerts using ADS-B In (ADS-B, ADS-R, and TIS-B) trafc
information. This feature is available for Release 2.0 or greater.
Both systems alert the ight crew of trafc 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 trafc information being correlated by the unit.
