1.7.2 TSO Deviations from Minimum Performance Standards
The following information lists the TSOs for the unit that requires a deviation to Minimum Performance
Standards (MPS) that are called out in the TSO and provides the justification for the deviation.
Deviations to TSO-C147 are applicable to the diversity variants only. Deviations to TSO-C113a are
applicable to the panel mount variants only.
Table 1-7: TSO Deviations
TSO NO. DEVIATION
TSOC-145c, 3.d TSO requires use of DO-160E for environmental qualification testing; DO-
160G was used instead.
TSOC-147, 1.c TSO requires use of DO-160D for environmental qualification testing; DO-
160G was used instead.
TSO-C145c, 4.c
TSO-C147, 2.c
TSO-C154c, 4.d
TSO-C166b, 4.d
The Lynx NGT-9000s utilizes electronic part marking for the software part
number, which is stored in non-volatile memory.
TSO-C113a, 4.a
TSO-C145c, 4.a & 4.e
TSO-C147, 2.a
TSO-C154c, 4.a
TSO-C157a, 4.a
TSO-C166b, 4.a
TSO-C195a, 4.a
Per the guidance in FAA Order 8150.1c, the appliances are marked with the
primary TSO along with a reference to the Installation Manual for the other
TSO information (other applicable TSOAs, deviations, etc.).
TSO-C112d, 3.d
TSO-C166b, 3.d
The Lynx NGT-9000s 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-
linearities 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
