Their argument is that this approval can only be given to someone with AOC
German reg aircraft & dealt with the LBA. Crews are CBT trained and they required that we have procedures and checked the A/Cs paperwork. No drama IMO as long as the AFM has anything on the capabilities of your avionic...

Denti,
Your LNAV/Baro VNAV minima are not only higher than LPV minima due to temp.comp.
The entire lateral approach sector geometry is different, basically 4x RNP wide, whereas LPV is angular, like an ILS. Also, the use of Vertical Error Budget to calculate obstacle clearance will raise minima.
Funnily enough, most countries allow you to fly their LNAV/Baro VNAV approaches using SBAS in stead of barometrically derived GPs - if your avionic suite allows you to do this. Doesn't change the minima, though, and certainly doesn't turn it into an LPV-approach. Still, better than being able to move the GP 300ft down by setting a QNH 10hPa too low ;-)
