Determining LNAV\VNAV and LPV minima design and the rare case of higher LPV minima
Hi,
Can anyone help?
I am trying to find an approved reference that explains why the scenario can arise that LPV minimas may be higher than LNAV/LNAV minimas in exceptional cases.
My understanding is that it is due to how the approaches are designed, with protected areas in relation to obstacles on the approach sector. (But will happily stand corrected)
Many thanks for people's time.
Tom

Differences usually due to the different obstacle clearance areas.
Here are some examples:
LPV lower than ILS...
LNAV lower than LNAV/VNAV: (MDA vs DA)
