The specimen flight manual supplement which can be found in the back of the GPS installation manual is OK for the
FAA.
For
EASA it's more complicated, apparently.
It would seem that my GPS unit was fitted before the authouritys had given any thought to the matter what so ever.
You are absolutely right there
For years it was common CAA practice, when doing the initial CofA on a new G-reg which has an IFR GPS, to placard the GPS as "VFR only" and (if possible, and on the KLN94 this is indeed possible) to force the dealer to configure the GPS for VFR only so that e.g. overlay approaches are not visible. Then, a few years later, they may have wondered why so few G-reg planes were able to fly those trial GPS approaches
