Some discussion about this point. Let's say your destination has an ils approach with an ndb as the non precision FAF and GS check, the missed approach is to a VOR. The ndb is notamed out of service, you have no gps/rnav. ATC says they will provide vectors for the ils. Is it legal to fly the ils without an ndb/fan marker/cross radial/dme? The precision FAF is the glideslope intercept altitude, but if you fly the GS there will be no altimeter/glide slope cross check.
Thoughts anyone?
