SECTION 1. GENERAL
1.1 Functional Description
The Lynx MultiLink Surveillance System (also referred to in this manual as the Lynx NGT-9000)
is a Mode S Level 2 dens Class 1 Transponder with an integrated GPS receiver providing
Automatic Dependent Surveillance-Broadcast (ADS-B) output using a 1090ES (Extended
Squitter). The unit also receives ADS-B data via 1090ES and UAT (978 MHz Universal Access
Transceiver). Figure 1-1 is a depiction of the NGT-9000.
The unit replies to Mode A, Mode C and Mode S interrogations receiving interrogations at 1030
MHz and transmitting responses at 1090 MHz. The unit is equipped with IDENT capability that
activates the Special Identification (SPI) pulse for 18 seconds.
Ground stations can interrogate Mode S Transponders individually using a 24-bit ICAO Mode S
address, which is unique to the particular aircraft. In addition, ground stations may interrogate
the unit for its transponder data capability and the aircraft's Flight ID.
The ADS-B provides own aircraft data with Enhanced Visual Acquisition (EVAcq) traffic
information that improves situational awareness and flight safety by providing aircraft position,
velocity, and heading information that is automatically transmitted from other aircraft and ground
stations providing immediate surveillance of air-to-air traffic.
In addition to ADS-B surveillance, the installed NGT-9000 includes an Active Traffic Awareness
System (TAS/TCAS), ADS-B Traffic Advisory System (ATAS) and Terrain Awareness and
Warning System (TAWS), as well as support for both top and bottom antenna diversity.
The 1090ES and UAT ADS-B data link have the following capabilities:
• 1030MHz/1090 MHz In – Receive ADS-R and TIS-B
• 1090ES OUT – Transmits 1090 MHz Extended Squitter ADS-B
• UAT IN – Receives 978 MHz ADS-B, ADS-R and TIS-B, FIS-B, NOTAMS, and TFR’s

FAA(Approved
1.2 NGT-9000 ADS-B Traffic Advisory System (ATAS) [Optional]
The ADS-B Traffic Advisory System (ATAS) is a passive system that monitors ADS-B, ADS-R
and TIS-B ADS-B IN data and alerts the flight crew via on-screen alerts aural traffic calls and an
optional Traffic Alert lamp to nearby aircraft and assists the pilot in the visual acquisition of
aircraft that may represent a danger. Refer to the Pilot's Guide, L3 p/n 0040-17000-01 Revision
H or later, for examples of on-screen symbology and aural alerts.
• 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.
• A Traffic Advisory (TA) is displayed when other aircraft are a potential threat.
• When ownship is in the airport environment, a Traffic 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.
• When the aircraft is outside the airport environment, aircraft that are within a range of 6
nmi of ownship with a vertical distance of +/- 1200 ft (if altitude is reporting) are classified
as a Proximate Advisory (PA). A PA is displayed only for aircraft that are in air.
• ATAS and TAS/TCAS may operate at the same time with traffic information being
correlated by the unit
When ATAS is installed, an Audio Acknowledge button will cancel the current aural
announcement.
1.3 NGT-9000 Terrain Awareness and Warning System (TAWS) [Optional]
The Terrain Awareness and Warning System (TAWS) is an optional function that is set up
during installation. The TAWS function continuously monitors the aircraft’s position, altitude,
speed, track, and phase of flight and compares the information to the terrain database loaded
during installation. Terrain and obstacle hazards are indicated by cautions and warnings using
screen annunciators, aural terrain alerts, and Terrain Caution and Warning alert lamps. Refer to
the Pilot's Guide, L3 p/n 0040-17000-01 Revision H, or later, for examples of on-screen
symbology and aural alerts.
The TAWS function uses Forward Looking Terrain Avoidance (FLTA) and Ground Proximity
Warning System (GPWS) functionality to determine when a terrain alert or altitude callout is
triggered due based on the following conditions:
• Reduced required terrain or obstacle clearance (FLTA)
• Imminent terrain impact (FLTA)
• Premature descent
• Excessive descent rate (GPWS)
• Negative climb rate or altitude loss after takeoff (GPWS)
• Passing an altitude of 500 ft (GPWS)

There are four TAWS configurations available with the NGT-9000:
• Disabled
• TAWS B – Default Aural Phrases
• TAWS B – Alternate Aural Phrases
• Display Only – No Alerts
When a TAWS configuration is enabled with audio, an Audio Acknowledge button will cancel the
current aural announcement.
1.4 NGT-9000+ Traffic Awareness Overview [Optional]
The NGT-9000+ (“9000 Plus”) supports optional active Traffic Awareness System (TAS) and
Traffic Conflict Avoidance System (TCAS).
The TAS/TCAS options are active systems that operate as aircraft-to-aircraft interrogation
devices. 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. Refer to the Pilot's Guide, L3 p/n
0040-17000-01 Revision K or later, for examples of on-screen symbology and aural alerts for
each system.
• The system display shows the relative position of traffic using text, shapes (i.e., Traffic
Advisory = solid circle; Other Traffic = open diamond) and colors.
• The effective active-mode surveillance range is 35 nm and the system is capable of
tracking 35 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
minimum, a radius of 35 nm and extends 10,000 ft above and 10,000 ft below own
aircraft.
• The system uses a voice audio output that announces Traffic Advisory and relative
altitude (with optional Extended Call-outs enabled).
• The TCAS option qualifies as a TCAS I system and as such, offers only Traffic
Advisories (TA) (“Traffic, traffic. 12-O’clock, one mile”) but not Resolution Advisories
(RA) such as “Climb, climb”.
1.5 NGT-9000D Antenna Diversity Overview [Optional]
The NGT-9000D has the same hardware and firmware/software as the basic NGT-9000, but is
capable of supporting dual L-band antennas (one bottom and one top) to enhance system
performance and prevent fuselage blanking of a single bottom antenna in tight turns into a
ground station or UAT target. The upper L-band antenna may be a single blade antenna or the
optional Directional Antenna.
1.6 Capabilities
The NGT-9000 transceiver can be software configured as either an NGT-9000, 9000+, or
9000D. It can also be installed with, or without TAWS and peripheral ARINC-429 or RS-422
panel mounted traffic and weather displays.
