1.2.6 Traffic Display Functional Overview
The Lynx NGT-9000 monitors the airspace around the aircraft using ADS-B In (and TAS/TCAS if
equipped) to show other aircraft on the screen. When within range of a participating ground station TIS-B
and ADS-R traffic services are also shown on the screen. Traffic is identified on the screen using
corresponding traffic symbols.
The unit also provides TAS, TCAS, and ATAS traffic advisories when TAS, TCAS, and/or ATAS
configurations are enabled. A voice audio output announces relative altitude and traffic alerts. The unit
has multiple transmit/receive ARINC 429, RS-422, and RS-232 data ports used to transmit data to traffic,
weather, and PED displays.
The unit provides the transponder code, reply symbol, and mode of operation to the display.
1.2.7 FIS-B System Overview
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 (CONUS/ NEXRAD /AIRMETS/
SIGMETS/ NOTAMS/ METARS, etc.), TFR, and TAF (FIS-B products).
NOTE
CONUS and Regional NEXRAD may not always contain complete data. The data
is refreshed every 15 minutes and it is likely to be updated in a future cycle.
FIS-B is advisory information only and is intended to enhance pilot decision-making during strategic
flight planning. FIS-B augments traditional sources of this information such as ATC and Flight Service
Station (FSS). FIS-B information is provided over the ADS-B Services network on the 978 MHz UAT
link when in ground station coverage.
1.2.8 Traffic Awareness System (option) Overview
The Traffic Awareness System (TAS) option is an active system that operates as an aircraft-to-aircraft
interrogation device. The unit interrogates transponders in the surrounding airspace similar to ground
based radar. When replies to these active interrogations are received, the responding aircraft’s range,
altitude, and closure rates are computed to plot traffic location and predict collision threats. The unit alerts
the flight crew to nearby transponder-equipped aircraft and assists the pilot in the visual acquisition of
aircraft that may represent a danger. Traffic information, out to a selected range, is graphically displayed
on the unit or alternate display. See Figure 1-3 for an example of own aircraft traffic (UAT, 1090ES, TIS-
B, and TAS).
• The system display shows the relative position of traffic using text, shapes and colors.
• The effective active-mode surveillance range is 35 nmi and track 35 ATCRBS intruders
simultaneously with the target bearing relative to the nose of own aircraft.
• The tracking of targets is in a cylindrical volume centered on own aircraft that has, at a maximum, a
radius of 35 nmi and extends 10,000 ft. above and 10,000 ft. below own aircraft.
