1.14 INSTALLATION APPROVAL AND LIMITATIONS
1. This article meets the minimum performance and quality control standards required by the applicable
technical standard orders (TSOs). Those installing this article, on or in a specific type or class of
aircraft, must determine that the aircraft installation conditions are within the applicable TSOs
standards. TSO articles must have separate approval for installation in an aircraft. The article may be
installed only according to 14 CFR parts 43 or the applicable airworthiness requirements.
2. All antennas used in the installation must meet the requirements specified in this manual.
3. The GPS receiver must use antenna meeting the requirements specified in this manual.
4. The use of a frequency diplexer is not supported and as such, the L-Band antenna cannot be diplexed
with another L band antenna.
5. A GPS Splitter or Coupler may be used. Refer to paragraph 1.11.2.1 for recommended model. Install
the compatible GPS Splitter or Coupler using the guidance of AC 43.13-2B or other FAA Approved
guidance deemed appropriate for each specific aircraft model.
6. It is the installer’s responsibility to ensure the ADS-B Out system is compliant with AC 20-165B, 14
CFR 91.225 (b) and 91.227 when installed in accordance with ACSS installation instructions.
7. If aircraft ground speed is less than 14 knots, and there is not a valid heading input into the unit, then
“Traffic Unavailable” TAS traffic data only may be displayed. No traffic is displayed if TAS/TCAS
is in standby.
8. The Lynx NGT-9000 may be optionally configured to support the following functions: TAS, TCAS,
Diversity, ATAS, TAWS (except on helicopters), and Terrain Display Only (No Alerts) (i.e. Terrain
Vision).
9. The Class B TAWS function may only be activated on fixed wing aircraft.
10. A heading source is required for helicopter installations with the ATAS functions.
11. The Terrain Display Only (No Alerts) (i.e. Terrain Vision) function option may be activated on
either fixed wing aircraft or helicopters.
12. The NGT-9000RD or RD+ is not capable of driving a terrain display.
13. In compliance with FAA Advisory Circular AC20-172B Section 2-8e, if the NGT-9000 is installed
in an aircraft with an existing traffic system that generates traffic alerts, the NGT-9000 ATAS and
TAS/TCAS functions must be disabled. This ensures that only one traffic system is alerting.
14. 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 will not provide the full TSO-C157a FIS-B

Temperatures Aloft are unavailable on the NGT-9000 panel mount display. Lynx weather products
will continue to display via an external display or via WiFi to a portable electronic device. The Lynx
Transponder and Lynx ADS-B Out functions are not impacted and the system continues to comply
with these regulatory requirements. This issue will re-occur approximately every 20 years when the
Epoch rollover occurs.

weather products such as the METARS, Winds Aloft, and Temperatures Aloft will be unavailable on
the NGT-9000 panel mount display. Lynx weather products will continue to display via an external
display or via WiFi to a portable electronic device. The Lynx Transponder and Lynx ADS-B Out
functions are not impacted and the system continues to comply with these regulatory requirements.
