FAQ n.46837

The functionality of the Garmin GTN series exceeds the one covered by CS-SC052b and thus its installation is not eligible for CS-STAN.

Garmin is holding an STC with a comprehensive AML for the installation of the GTN series. In cases where a European type is not listed on that AML, due to the absence of a FAA TC, the process of a minor modification or Form 134 could be used to extend the applicability of the STC, if agreed by EASA.
