I am going to do my CFII checkride in a few weeks and my DPE wants to do RNAV approaches to satisfy the Non-Precision and Precision approaches tasks on the PTS/ACS.
According with the Instrument ACS an RNAV (GPS) approach with LPV minimums can be used to satisfy the precision approach task as long at it has a DH lower than 300 ft. I don't have a problem with that, the airport has an LPV approach with LPV minimum of DH 250 ft.
Now for the non-precision approach, I am going to use the same approach but flying the LNAV minima. So my question, since I haven't flown LNAV minima since my IFR training, my question is: Can I fly the LNAV MDA even if the GPS annunciator is on LPV mode? I guess the answer is yes, so, is there any consideration when doing that?
And just for future applicants, an LPV approach with greater than 300 ft DH can be used to satisfy the Non-precision approach task on the ACS (instrument ACS page A-17).
