Substituting MAP timing with GPS
Asked by: Alex J 2146 views FAA Regulations, Instrument Rating, Student Pilot
Assume you’re performing a non precision approach where the MAP is defined by timing from the FAF to the MAP.
Is substituting this timing with a certified IFR GPS legal? Assume you have loaded the approach and the GPS has automatically added the MAP (RWxx) into the flightplan. You are not using the GPS to navigate to this waypoint (still using the loc/vor to laterally get there) only to identify it.
Is there FAA docs (AIM/FAR/Handbook/ACs) that support this one way or the other.
One example is the ILS OR LOC 05 at KHUF. If flying the LOC, the only way you can identify the MAP is via timing.
