Document Precedence

This Pilot’s Guide provides general information about the operation
of the NGT-9000. Refer to your FAA-approved Airplane Flight Manual
(AFM) and its flight manual supplements for information specific to
your aircraft. If there is conflicting information between the AFM and
this guide, the AFM takes precedence over this guide.

Disclaimer

This Pilot’s Guide is subject to change without notice. The illustrations
in this guide are typical for the Lynx NGT-9000.

Screen information may look different on displays interfaced with
the Lynx NGT-9000. Refer to the pilot’s guide for that display for a
description of how information is depicted.

All pilots/operators are reminded that the airborne equipment that
displays other ADS-B equipped aircraft and transponder equipped
aircraft via TIS-B is only for pilot situational awareness. This equipment
is not approved as a collision avoidance tool. Any deviation from an air
traffic control clearance based on cockpit information must be approved
by the controlling ATC facility prior to commencing the maneuver.
Uncoordinated deviations may place an aircraft in close proximity to
other aircraft under ATC control not seen on the airborne equipment
and may possibly result in the issuance of a pilot deviation.

ADS-B is currently being deployed throughout the National Airspace
System (NAS). The availability of ground based transceivers (GBT) is
limited to selected areas. For information regarding the FAA’s system
of ADS-B, TIS-B, ADS-R, and FIS-B refer to the FAA’s Aeronautical
Information Manual sections 4-5-7 to 4-5-10.

DESCRIPTION

INTRODUCTION

The Lynx NGT-9000 family of products are a Mode S Level 2 dens
Class 1 Transponder with an integrated GPS receiver providing
Automatic Dependent Surveillance-Broadcast (ADS-B) output using
1090ES (Extended Squitter). The Lynx NGT-9000 also receive ADS-B
data via 1090ES and UAT (978 MHz Universal Access Transceiver).

The panel mounted version of the Lynx NGT-9000 has a multifunction
touch screen display that allows the user to view transponder, traffic,
and weather information. The touch screen provides the means to
select screen views and interface with transponder, traffic, and weather
displays. See Figure 1-1.

The remote version of the Lynx NGT-9000 provides the same
functionality as the panel mount, but is controlled using a compatible
alternate display or controller. See Figure 1-2.

In addition to ADS-B surveillance, some models of the Lynx
NGT-9000 include an Active Traffic Awareness System (TAS) as well
as support for antenna diversity. Table 1-1 provides model and part
number information.

Description

PILOT ADVISORY

The display of ADS-B data only supplements and does not replace
any operational procedure. All pilots/operators are reminded that the
airborne equipment that displays traffic is only for pilot situational
awareness. This equipment is not approved as a collision avoidance
tool and does NOT relieve the pilot of responsibility to “see-and-avoid”
other aircraft. Any deviation from an air traffic control clearance based
on cockpit information must be approved by the controlling ATC facility
prior to commencing the maneuver. Uncoordinated deviations may
place an aircraft in close proximity to other aircraft under ATC control
not seen on the airborne equipment and may possibly result in the
issuance of a pilot deviation.

•

You may receive an intermittent TIS-B aircraft display of your
aircraft, typically when you are maneuvering (e.g., climbing turn)

- due to the radar not tracking you as quickly as ADS-B does.

•

The TIS-B position update is approximately 3-13 seconds depending
on the radar coverage in which you are flying. The update rate for
ADS-B is approximately every second.

•

The TIS-B system currently only sees transponder equipped
aircraft. No transponder = no TIS-B other aircraft. Always look
outside.

•

Pilots flying in visual meteorological conditions (VMC) are reminded
that visual contact remains the only means of self separation. There
is currently no indication provided when you are operating inside
(or outside) the TIS-B Service Volume, therefore it is difficult to
know when you should be receiving all traffic information – assume
you are not.

•

Information shown on the display is provided to the pilot as an aid
to visually acquiring traffic. When under ATC control pilots should
maneuver their aircraft based only on ATC guidance or positive
visual acquisition of the conflicting traffic. Maneuver should be
consistent with ATC instructions. ATC should be contacted for
resolution of the traffic conflict.

•

The transponder signal must be transmitting during all flight
operations. It may be turned OFF only if the system is inoperable
or if advised by ATC to disable ADS-B.

•

An invalid input to the NGT-9000 may not stop operation, but may
degrade performance. Invalidities may self correct depending on
the issue.

•

Other aircraft may not be displayed if the integrity of the data being
received from ADS-B, ADS-R, or TIS-B is not sufficient to create an
accurate target on the display.

Lynx ® NGT-9000

Pilot’s Guide 1-5

Description

FUNCTIONAL DESCRIPTION

The panel mount versions of the Lynx NGT-9000 can display and
control the following information:

Flight ID or aircraft Tail Number

•
Transponder (MODE S) and Traffic Mode of Operation

•
Derived Altitude Data

•
ADS-B On/Off status

•
VFR Select and Squawk Code Input

•
IDENT

•
Traffic (graphic and textual)

•
Weather (graphic and textual)

•
TAS Mode (model specific)

•

The remote mount versions of the Lynx NGT-9000 provides the same
functionality as the panel mount, but is controlled using a CP-2500
Control Panel. Display information is shown on a optional compatible
display or PED. See Figure 1-2.

Figure 1-2: Example of Remote Mount Lynx NGT-9000

The Lynx NGT-9000 replies to Mode A, Mode C and Mode S
interrogations on 1030 MHz and transmitting responses at 1090
MHz.

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.

Models with the TAS option provide TAS traffic advisories and a voice
audio output that announces Traffic Advisories and relative altitude.

The unit has multiple transmit/receive ARINC 429, RS-422 and RS­232 data ports used to transmit data to traffic, weather, and PED
displays.

Lynx ® NGT-9000

Pilot’s Guide1-6

Description

The unit provides the transponder code, reply symbol and mode of
operation to the display.

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 to other aircraft and
ground stations providing immediate surveillance of air-to-air traffic.
The 1090ES and UAT ADS-B data link have the following capabilities

1090 In - Receives ADS-B, ADS-R and TIS-B

•
1090ES Out - Transmit ADS-B

•
UAT In - Receives ADS-B, FIS-B, ADS-R, TIS-B

•

A description of these functions are provided below. A composite of
UAT / 1090ES traffic (UAT, 1090ES, ADS-R, and TIS-B) is provided
in Figure 1-3.

Model Options

The Traffic Awareness System (TAS) option provides the system
the capability to interrogate nearby aircraft transponders and issue
Traffic Advisory (TA) alert to the flight crew. This option requires the
installation of a directional antenna.

The Diversity option offers enhanced traffic awareness via 1090MHz
using the ADS-B service. This option requires the installation of an
additional top mounted UAT (L-Band) antenna.

Automatic Dependent Surveillance - Broadcast (ADS-B)

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 nearby like equipped aircraft (with Mode S or
UAT) using ADS-B Out. The ADS-B Out (1090ES) function is used
to periodically broadcast (without interrogation) information about the
aircraft that includes aircraft identification, position, altitude, velocity
and other aircraft status information.

ADS-B is NOT intended to be used as a collision avoidance system

•
and does NOT relieve the pilot of responsibility to “see-and-avoid”
other aircraft.

No avoidance maneuvers are provided for, nor authorized, as a

•
direct result of a ADS-B other aircraft being displayed in the cockpit.
Avoidance maneuvers must be based on visually acquiring the

Description

The traffic display shows the relative position of ADS-B or standard

•
traffic using text, shapes, and colors. ADS-B also provides similar
information on ADS-B equipped ground vehicles.

The effective surveillance range is 60 nmi. The passive-mode

•
surveillance range is 160 nmi and maintains report messages
for a minimum of 200 1090ES ADS-B participants and 300 UAT
ADS-B participants simultaneously. To reduce display clutter a
set number of other aircraft of the highest priority other aircraft
are displayed at a time.

Automatic Dependent Surveillance – Re-broadcast (ADS-R)

ADS-R is a ground based broadcast service that repeats ADS-B
messages from one link (1090 MHz or 978 MHz) to the other link for
aircraft with ADS-B In.

ADS-R is NOT intended to be used as a collision avoidance system

•
and does NOT relieve the pilot of responsibility to “see-and-avoid”
other aircraft.

No avoidance maneuvers are provided for, nor authorized, as a

•
direct result of a ADS-R other aircraft being displayed in the cockpit.
Avoidance maneuvers must be based on visually acquiring the
target.

The actual availability of services depends upon both the availability

•
of a ground station to support ADS-R source data and aircraft being
within range of the ground station.

ADS-R transmissions are updated at least every 2 seconds on the

•
surface, 5 seconds in the terminal area, and 10 seconds in the en­route airspace.

Other aircraft are provided by the ground station if within a 15 nm

•
horizontal range and +/-5,000 ft of altitude of the receiving aircraft.
ADS-B equipped ground aircraft and vehicles are not displayed to
airborne aircraft.

An aircraft on the ground receiving ADS-R is provided both ground

•
aircraft and vehicles as well as airborne other aircraft within 5nm
and 2,000 ft above ground level of the airport reference point.

Description

Traffic Information Service - Broadcast (TIS-B)

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.

The actual availability of services depends upon the availability of

•
ground-based radar to support TIS-B source data.

Receiving aircraft must be in both ATC radar coverage and ground

•
based transceiver (GBT) coverage in a given area to receive
TIS-B service in that area. When ownship is above 24,000 ft, the
ground station will no longer provide TIS-B service. (Targets will
be provided up to 27,500 ft) To reduce display clutter, the TIS-B
service provides traffic information on other aircraft within 15 nmi
and +/- 3500 ft of ownship.

Other aircraft are provided by the ground station if within a 15nm

•
horizontal range and +/-3,500 ft of altitude of the receiving aircraft.
ADS-B equipped ground aircraft and vehicles are not displayed to
airborne aircraft.

Aircraft not equipped with a transponder, or equipped with a Mode

•
A only transponder are not part of the TIS-B data and will not be
seen on the traffic display.

The ground station will not provide display information for Mode

•
C and Mode S transponder equipped aircraft that do not provide
altitude information.

An aircraft on the ground receiving TIS-B is provided both ground

•
aircraft and vehicles as well as airborne other aircraft within 5nm
and 2,000 ft above ground level of the airport reference point.

The TIS-B service is intended to improve the pilot’s ability to visually

•
see traffic in the air and on the airport surface so that pilots can
more effectively apply traditional “see-and-avoid” techniques.

TIS-B is NOT intended to be used as a collision avoidance system

•
and does NOT relieve the pilot of responsibility to “see-and-avoid”
other aircraft.

No avoidance maneuvers are provided for, nor authorized, as a

•
direct result of a TIS-B other aircraft being displayed in the cockpit.
Avoidance maneuvers must be based on visually acquiring the
target.

Description

Traffic Awareness System (TAS)

The TAS option is available with model NGT-9000+ and NGT­9000R+. TAS is an active system that operates as an aircraft-to­aircraft interrogation device. The unit interrogates transponders in the
surrounding airspace similar to ground based radar; with an effective
active-mode surveillance range of 35 nmi. 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 NGT-9000+ or NGT-9000R+ 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 NGT-9000+ or alternate display.

The system display shows the relative position of traffic using text,

•
shapes (i.e., Traffic Advisory = solid circle; Other Traffic = open
diamond, Proximate Traffic = solid diamond) and colors.

The effective active-mode surveillance range is 35 nmi and

•
track 35 ATCRBS intruders simultaneously with the other aircraft
bearing relative to the nose of own aircraft.

The tracking of other aircraft is in a cylindrical volume centered

•
on own aircraft with a maximum radius of 35 nmi and extending
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.

Refer to Chapter 4 Principles of TAS Operation for more information.

Flight Information Service - Broadcast (FIS-B)

FIS-B is a FAA ground based broadcast service providing graphical
and textual display of weather and aeronautical information. Table 1-1
provides a description of the various products available via the FIS-B
broadcast.

The broadcast includes Airmen’s Meteorological Information
(AIRMET), Significant Meteorological Information (SIGMET), Aviation
Routine Weather Report (METAR), Regional and Next-Generation
Radar (NEXRAD), display of CONUS radar information, Notices
to Airmen (NOTAM), Terminal Aerodrome Forecast (TAF), Winds
and Temperatures Aloft, TIS-B Service Status, Temporary Flight
Restrictions (TFR) and Aviation Special Selected Weather (SPECI).

FIS-B information is to be used for pilot planning decisions and pilot
near-term decisions focused on avoiding areas of inclement weather
that are beyond visual range or where poor visibility precludes visual
acquisition of inclement weather. FIS-B weather and National Airspace
System (NAS) status information may be used as follows:

To promote pilot awareness of ownship location with respect to

•

reported weather, including hazardous meteorological conditions,
NAS status indicators, and enhance pilot planning decisions and
pilot near-term decision-making.

To cue the pilot to communicate with the Air Traffic Control

•

controller, Flight Service Station specialist, operator dispatch, or
airline operations control center for general and mission critical
meteorological information, NAS status conditions, or both.

FIS-B information including weather information, NOTAMs, and TFR
areas are intended for the sole purpose of assisting in long- and near­term planning decision making. The system lacks sufficient resolution
and updating capability necessary for aerial maneuvering associated
with immediate decisions.

a TAF is a 9- or 12-hour forecast, though some TAFs
can cover an 18- or 24-hour period. TAFs comple­ment and use similar encoding to METAR reports.
They are produced by a human forecaster based on
the ground. For this reason there are fewer TAF lo­cations than there are METARs. TAFs can be more
accurate than Numerical Weather Forecasts, since
they take into account local, smallscale, geographic
effects.

Winds and Temperature Aloft Forecast is forecast for
specific atmospheric conditions in terms of wind and
temperature in a specific altitude measured mostly in
feet (ft) above mean sea level (MSL). The forecast is
specifically used for aviation purposes.
