Foreword Getting Started Xpdr Ctrl NOTE: If you attempt to intercept the approach course at a distance less than 2.0 NM from the FAF, the GTN 6XX does not automatically switch the CDI to VLOC. In this case, touch the CDI key to manually switch from GPS to VLOC. Com/Nav The automatic switch from GPS to VLOC is not immediate, but instead occurs gradually to prevent abrupt CDI changes when coupled to an autopilot. The CDI FPL selection can also be changed manually by touching the CDI key. 6.12 RNAV Approach Procedures Direct-To The GTN 6XX allows for flying LNAV, LNAV/VNAV, LNAV + V, LP, and LPV Proc approaches according to the published chart.
