Maybe this: The calculation of the LNAV/VNAV glidepath and minimums are
not based on a WAAS-enabled GPS. They are based on a barometric system our airplanes don't have.
An approach plate has all the minimums available for an approach, whether you have the equipment to fly it or not. If you have a 430 (not WAAS) the approach plate will still have the LPV minimums.
My question was about the annunciation? Does the unit annunciate LNAV/VNAV? Not what to do if it does. I saw the simulator did, but that doesn't necessarily mean that's what happens in real life.
@RussR answered that for me.
The disagreement I mentioned (and am not answering) is what happens if you have LNAV/VNAV minimums
lower than LPV minimums and the system annunciates LPV. Can you fly to the
lower LNAV/VNAV minimums?
