Lynx NGT-9000
Installation Manual
1.2 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 providing Automatic Dependent Surveillance-Broadcast
(ADS-B) out on 1090 MHz with an integrated GPS receiver. The unit also receives ADS-B data via 978
MHz and 1090 MHz. Some models support optional Active Traffic (TAS or TCAS) and/or antenna
Diversity functionality.
Maintenance and configuration setup is accomplished via the USB port located on the front of the unit or
by an optional WiFi connection.
1.2.1 Software Release Summary
Release 2.0 provides the optional functions of ATAS (ADS-B Traffic Advisory System) and Class B
TAWS (Terrain Awareness and Warning System).
Release 2.1 provides the optional function of Lightning Detection, a discrete switch option for setting the
transponder to Standby, additional display interfaces, and an option to display terrain without audio and
visual alerting.
Release 3.0 provides the optional function of Traffic Alert and Collision Avoidance System (TCAS) that
would be used in place of the TAS function. Note – This is a TCAS I system that will be referenced as
“TCAS” throughout the manual.
Release 3.1 improves SBAS GNSS satellite tracking and HFOM reporting.
Release 3.2 incorporates a new ARINC 429 Control Panel interface and an option for dual ARINC 429
Control Panels. Allow ATAS to be enabled without enablement code. See Service Bulletin SB9029000-8
for other resolved issues. New RS-232 Control Panel feature for Reply Rate (not used by the CP-2500).
An upgrade to Release 3.2 requires certain configuration options be selected for the dual Control Panel
feature. If the configuration settings are not made, the unit reverts to Release 3.0/3.1 behavior but with
Release 3.2 fixes. The NGT-9000R cannot meet both Release 3.0/3.1 and Release 3.2 ARINC 429 Output
capabilities because the single ARINC 429 output is used for either Display (CDTI) output associated
with Release 3.0/3.1 or Control Panel feedback associated with Release 3.2.
In addition updates to the MPC (MAT) include removing selection of NY-164 and changing the “save”
button function into a “save all” button.
Release 3.2.1 is a minor software update to fix GPS Epoch Rollover issue that results in the panel mount
versions of the NGT-9000 System (HW Part No. 9029000-20000) with Software Release Versions 1.0,
1.1, 1.2, 2.0, 2.1, 3.0, 3.1, and 3.2 not providing the full TSO-C157a FIS-B functionality during the period
of 6 April 2019 thru 31 December 2019. See SB9029000-9.
Release 3.2.2 is a minor software update that will reduce Traffic Fail message messages and correct
ground velocity computations. See SB9029000-10. This updated includes an update to the MPC (MAT)
software.
0040-17001-01 (Revision W) General Information Page 1-4
Lynx NGT-9000
Installation Manual
1.2.2 Transponder Functional Overview
The unit receives Mode A, Mode C, and Mode S interrogations on 1030 MHz and replies on 1090 MHz.
The unit is equipped with IDENT capability that activates the Special Identification (SPI) pulse for 18
seconds.
Ground stations and airborne TCAS 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.
1.2.3 GPS Functional Overview
The GPS function utilizes signals from Global Positioning System (GPS) satellite constellation and
Satellite-Based Augmentation Systems (SBAS) such as the USA Wide Area Augmentation System
(WAAS), European EGNOS, Indian GAGAN, and the Japanese MSAS. Currently it supports WAAS and
WAAS compatible SBAS systems.
The internal GPS function provides position, velocity, time, and integrity (NIC, NACp, etc.) information to
the ADS-B functions and meets the requirements of 14 CFR 91.227.
1.2.4 Lightning Detection (optional)
Release 2.1 and later. The WX-500 Stormscope is a Weather Mapping System that provides lightning
discharge information. This information is shown on the right application screen of the NGT-9000 Panel
Mount unit.
1.2.5 ADS-B System Overview
The ADS-B system has the following capabilities:
• 1090ES In (1090MHz) - Receive ADS-B, ADS-R and TIS-B
• 1090ES Out (1090MHz) - Transmit ADS-B
• UAT In (978MHz) - Receive ADS-B, ADS-R, TIS-B, and FIS-B data
The Automatic Dependent Surveillance-Broadcast (ADS-B) improves situational awareness and flight
safety by providing real time traffic information. The ADS-B In function is used to receive ground station
supported TIS-B and ADS-R traffic, and direct communication with ADS-B out equipped aircraft.
The ADS-B Out (1090MHz) function is used to periodically broadcast (without interrogation)
information about the aircraft that includes aircraft identification, position, altitude, velocity and other
aircraft status information.
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.
Traffic Information Service Broadcast (TIS-B) is a ground based broadcast service that provides
secondary surveillance radar (SSR) derived traffic data (ATC transponder equipped aircraft not equipped
with ADS-B Out capability) to ADS-B In equipped aircraft.
0040-17001-01 (Revision W) General Information Page 1-5
Lynx NGT-9000
Installation Manual
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, TISB, 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.

1.2.9 ADS-B Traffic Advisory System Overview (optional)
Release 2.0 and later. The ADS-B Traffic Advisory System (ATAS) [previously referred to as TSAA]
function provides traffic advisories using ADS-B In information via aural announcements over the
cockpit speakers or headset and visually via the display or a cockpit lamp. ATAS and TAS/TCAS may
operate at the same time with traffic information being correlated by the unit.
• The system display shows the relative position of traffic using text, shapes and colors.
• The dimensions of Collision Airspace Zone (CAZ) are 500 ft. horizontal radius and +/- 200 relative
altitude.
•The dimension of the Protected Airspace Zone (PAZ) is dependent on closure rate. The PAZ
dimension decreases as closure rate decreases with a minimum 500 ft. horizontal radius and +/- 300
ft. (Sensitivity A) or +/- 500 ft. (Sensitivity B) relative altitude.
•The effective active-mode surveillance range is 40 nmi and track 60 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 20 nmi and extends 10,000 ft. above and 10,000 ft. below own aircraft.
1.2.10 Traffic Alert and Collision Avoidance System (option) Overview
Release 3.0 and later. The Traffic Alert and Collision Avoidance System (TCAS I) 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.

1.2.11 Terrain Awareness and Warning System Overview (optional)
Release 2.0 and later. The Class B Terrain Awareness and Warning System (TAWS) function
continuously monitors the aircraft’s position, altitude, speed, track, and phase of flight and compares the
information to an internal terrain, obstacle, and runway database. If TAWS predicts a potential Controlled
Flight Into Terrain (CFIT) situation, the system alerts the pilot visually on the Lynx NGT-9000 display,
aural announcements over the cockpit speakers or headset, or via cockpit lamps (caution and warning).
•The Remote Mount NGT-9000R does not have a TAWS display available (audio and lamps only).
1.2.12 TerrainVision
Release 2.1 and later. This optional function provides a terrain display (“TERR Advisory”) similar to the
TAWS display but without visual or audio alerts.
• This function is not available for the Remote Mount NGT-9000R.
• TerrainVision

1.2.13 Discrete Inputs and Outputs Functional Overview
The Lynx NGT-9000 has discrete inputs and outputs available that can be interfaced to indicator lamps and
cockpit switches. The discretes are optional except as noted in the instructions found in the installation
section. Input and output discretes are normally open and are set to ground when active, unless otherwise
indicated.
•(Discrete Input 1) The IDENT switch activates the IDENT pulse, which highlights the aircraft’s
symbol on the ATC’s radar screen and is identified on the Lynx NGT-9000 or external display /
control panel when active.
•(Discrete Input 2) The Audio Mute input is used to mute all audio outputs coming from the Lynx
NGT-9000. Audio mute can be connected to other Caution and Warning Systems (CAWS) if
required (i.e. TAWS) that needs to mute the traffic system for a higher priority audio annunciation.
•(Discrete Input 3) The On-Ground input (i.e. WOW) is used to signal the Lynx NGT-9000 that the
aircraft is on ground. The input can be connected to a squat switch, airspeed monitor, or a collective
switch. This discrete can be set in the DCM settings to either ground on ground, open on ground, or
not used.
•(Discrete Input 4) The Audio Acknowledge input is used to cancel the audio from a TAWS or
Traffic Aural. This discrete is used only when the optional TAWS, TAS/TCAS, or ATAS
functionality is configured.
•(Discrete Input 5) Release 3.2 and later. The Control Panel Select input is used to select ARINC 429
interfaced Control Panel #1 or #2. This input must be connected to the control panel LRU that
performs this selection.
•(Discrete Input 6) The Standby Mode input is used to place the unit’s transponder into Standby. It is
intended for use when dual transponders are installed on the aircraft.
•(Discrete Output 1) The TAWS Caution lamp (amber) is used to indicate a terrain caution advisory is
present.
• (Discrete Output 2) The TAWS Warning lamp (red) is used to indicate a terrain warning is present.
• (Discrete Output 3) The Traffic Alert lamp (amber) is used to indicate a TAS/TCAS, or ATAS
Traffic Advisory (TA).
•(Discrete Output 5) The Audio Mute can be connected to other CAWS alerting systems, if required,
that need to mute the traffic system (i.e. TAS/TCAS) for a higher priority audio annunciation (i.e.
TAWS). This output will be active when the Audio Mute Input (Discrete Input 2) is active.
•(Discrete Output 6) The ADS-B Out Fail lamp (amber) is used to indicate that ADS-B out is not
providing ADS-B output data. The lamp has multiple visual cues used to identify operational status.
