1.10 Certification
The GTR/GNC has been shown to meet compliance with the claimed TSO(s) when interfaced with the
equipment defined in this manual, and installed in accordance with the requirements and limitations as
defined in this manual.
The installer should verify non-Garmin devices, which are to be interfaced with the GTR/GNC, meet the
installation requirements identified in this manual to assure the installed system will comply with the
Garmin TSO/ETSO authorization. Garmin installation requirements will specify the interfaced device has
appropriate TSO/ETSO authorization. In some cases, the non-Garmin device may also be required to meet
additional Garmin specifications.
The Appliance Project Identifier (API) for the GTR/GNC is GMN-00999. The API is for project
identification with the FAA and EASA. In addition, the alpha character appended to the API in the ETSO
certificate is added to supplement project identification by EASA. This alpha character does not represent
a version number. See applicable hardware and software part numbers to identify appliance approvals.
