Instrument approach OTS components
I agree with everyone in regards to not being able to legally shoot the IAP since the MAP is part of the IAP.
Take KJVY ILS 18 as a current example. The MAP calls for going to the ABB VORTAC and holding. Since the ABB VORTAC was wiped out with one of those crazy winter tornadoes, a NOTAM was published regarding alternate MAP. There's already an alt MAP on the plate, but there's still a NOTAM for the MAP.
Good question though! Made me think and discuss it for a bit earlier tonight.
