Rev. 4 Page C-3
C.3 Altitude Serializer or Fuel/Air Data
Altitude serializers/encoders not listed below can still be approved under this GTN AML STC if all of the
following conditions are met:
• The altitude serializer/encoder is TSO approved;
• The installation of the altitude serializer/encoder was previously FAA-approved;
• The interface check for the altitude serializer/encoder described in Section 5.6.10 must be
successfully completed.
• The connections to the GTN must utilize shielding wiring of the type specified in this manual.
Shields must be terminated on the GTN side to connector shield block ground and on the Altitude
Serializer or Fuel/Air Data installation data. If the Altitude Serializer or Fuel/Air Data installation
data does not specify a shielding method then terminate the shield at the Altitude Serializer or
Fuel/Air Data using the guidelines provided in Section 2.4.11.4.
