Description
Traffic Advisory System (TAS)
The Trafc Advisory System (TAS) is an optional feature of the Lynx
NGT-9000. This feature provides the capability to interrogate nearby
aircraft transponders and issue Trafc Advisory (TA) alert as well as
a voice audio output that announces Trafc Advisories and relative
altitude to the ight crew. This option requires the installation of a
directional antenna.
ADS-B Traffic Advisory System (ATAS)
Release 2.0 or greater. The ATAS [also referred to as TSAA] option
provides trafc alerts using ADS-B In (ADS-B, ADS-R, and TIS-B)
trafc information. The TA alerts the ight crew aurally and visually in a
manner similar to a conventional Trafc Advisory System (TAS) which
assists the pilot in the visual acquisition of aircraft that may represent
a danger. Trafc Alerts are graphically depicted on the Lynx NGT-9000
panel mount units or on compatible external displays. ATAS and TAS
may operate at the same time with trafc information being correlated
by the unit. Refer to page 2-30 for details on operation.
Traffic Display
The Lynx NGT-9000 monitors the airspace around the aircraft using
ADS-B In (and TAS if equipped) to show other aircraft on the screen.
When within range of a participating ground station TIS-B and ADS-R
trafc services are also shown on the screen. Trafc is identied on
the screen using corresponding trafc symbols.
The Automatic Dependent Surveillance – Re-broadcast (ADS-R) is a
ground based broadcast service that repeats ADS-B messages from
one link (1090ES or UAT) to the other link for aircraft with ADS-B In.
Trafc Information Service Broadcast (TIS-B) is a ground based
broadcast service that provides secondary surveillance radar (SSR)
derived trafc data (ATC transponder equipped aircraft not equipped
with ADS-B Out capability) to ADS-B In equipped aircraft.
The Flight Information Services - Broadcast (FIS-B) function provides
pilots with a cockpit display of certain aviation weather and aeronautical
information for awareness of own aircraft location with respect to
reported weather, including hazardous meteorological conditions.
A composite of UAT / 1090ES trafc (UAT, 1090ES, ADS-R, TIS-B,
and TAS) is provided in Figure 1-3.
