Indeed EASA still requires you to tune the Navaid, can't find the offical reference right now.
If the approach would be labeled as VOR RWY 27 (no GPS) can i still use the overlay?
What i mean by "using the GPS" I'm talking about the procedure that can be loaded by entering the procedure (proc) menu in the garmin.
This provides you with lateral guidance of the procedure. (the LNAV you mention) but is this an approved way of navigation in this phase?
EASA is rather unclear about this subject as is my POH :s When compared to the A32F FCOM which very clearly states this.. :s
Its funny how such an 'easy' subject can be this unclear/bad defined
