Deviation Notes:
Deviation 1: TSO-C145c, TSO-C147. Require the use of DO-160E for environmental qualification testing; DO-
160G was used instead.
Deviation 2: TSO-C113a, TSO-C118a, TSO-C145c, TSO-C147, TSO-C151c, TSO-C154c, TSO-C157a, TSO-
C166b, TSO-C195a, TSO-C195b Per the guidance in FAA Order 8150.1c, the units are marked with the primary
TSO along with a reference to the Installation Manual for the other TSO information (other applicable TSO’s,
deviations, etc.).
Deviation 3: TSO-C118a, TSO-C147. Due to the RF power requirement and inherent non-linearity in RF
transmitters, the harmonics of the transmitter exceed the RF radiated emissions limit in DO-160G. ACSS deviates
from DO-160G Section 21 Category M Radiated RF Emissions in the following frequency bands when the
transmitter is active:
• 2060MHz ± 5MHz (2nd Transmitter harmonic) Exceeds Cat M by as much as15.6dB
• 3090MHz ± 5MHz (3rd Transmitter harmonic) Exceeds Cat M by as much as 16.7dB
• 4120MHz ± 20MHz (4th Transmitter harmonic) Exceeds Cat M by as much as 22.7dB
• 5150MHz ± 5MHz (5th Transmitter harmonic) Exceeds Cat M by as much as 12.2dB
Deviation 4: TSO-C112d, TSO-166b. The Lynx NGT-9000 has an RF transmitter, which is used to generate both
the 1030MHz and 1090MHz waveforms for Mode S Transponder, ADS-B Out, and TAS functions. Due to the RF
power requirement and inherent non-linearity’s in RF transmitters, the harmonics of the transmitter exceed the RF
radiated emissions limit in DO-160G. ACSS deviates from DO-160G Section 21 Category M Radiated RF
Emissions in the following frequency bands when the transmitter is active:
• 2180MHz ± 7MHz (2nd Transmitter harmonic) Exceeds Cat M by as much as 19.3dB
• 3270MHz ± 23MHz (3rd Transmitter harmonic) Exceeds Cat M by as much as 22.0dB
• 4360MHz ± 23MHz (4th Transmitter harmonic) Exceeds Cat M by as much as 24.4dB
• 5450MHz ± 23MHz (5th Transmitter harmonic) Exceeds Cat M by as much as 21.4dB
Deviation 5: TSO-C145c, TSO-C147, TSO-C154c, TSO-C166b. The Lynx NGT-9000 utilizes electronic part
marking for the software part number, which is stored in non-volatile memory.
Deviation 6: TSO- C112d. The NGT-9000 does not perform Comm-A (broadcast or addressed) or Comm-B Air-
Initiated ADLP (Airborne Data Link Processor) link operations. The NGT-9000 meets the certification of Level 2
transponders except for the support of the above listed ADLP functions.
Deviation 7: TSO-C147. The use of traffic symbology as defined in DO-317A is equivalent level of safety to the
symbols define in TSO-C147. ACSS submits that the use of the 0.1 inch character size for the TAS characters
(relative altitude tag) and use of 0.163 inch traffic symbols provides an equivalent level of safety to the TSO-C147
specified character and symbol sizes.
Deviation 8: TSO-C195a. The ACSS ATCRBS and ADS-B traffic in a track-up orientation when heading source is
unavailable. ACSS believes that removing the ADS-B traffic or ATCRBS traffic from the display when the heading
input is not available would significantly reduce the value of the CDTI’s support in the pilot’s see and avoid
responsibilities.
DO-317A ASA AIRB application display TIS-B traffic, with a NACv of 0, as a non-directional track similar to EVAcq.
This removes the contradiction between requirements and is in-line with updates in the next revision of the MOPS
(i.e., DO-317B).
DO-317A ASA AIRB application will send TIS-B traffic display data by reporting the most recent non-zero NACv
reading confirmed over a 60 second interval.
The EVAcq and AIRB functions are set to unavailable when ownship position is beyond 85 degrees North or South
latitude. The result is a display of “Traffic Unavailable” on Panel mount units and an indication of “Standby” for
remote displays. However, for NGT-9000 installations, where TAS is enabled, the range/bearing based TAS
targets are displayed.
Deviation 9: TSO-C195b. The ACSS ATCRBS and ADS-B traffic in a track-up orientation when heading source is
unavailable. ACSS believes that removing the ADS-B traffic or ATCRBS traffic from the display when the heading
input is not available would significantly reduce the value of the CDTI’s support in the pilot’s see and avoid
responsibilities.
DO-317B ASA AIRB application display TIS-B traffic by reporting the most recent non-zero NACv reading
confirmed over a 60-second interval.
The EVAcq and AIRB functions are set to unavailable when ownship position is beyond 85 degrees North or South
latitude. The result is a display of “Traffic Unavailable” on Panel mount units and an indication of “Standby” for
