My question: if LPV gets it's altitude/profile info from the SBAS, what is used to define the Missed Approach point, which is charted as a "DA" on the FAA charts. If one were to use an altitude, wouldn't one use the aircraft altimeter, in which case an accurate QNH must be used, in which case an AWIS/ATIS would be required?
