Hi all,

a question that has probably been asked before, but I couldn't find it
in Google:

Is it allowed to use an IFR-approach-certified GPS instead of a DME in
a LOC-DME or VOR-DME approach that does not have a GPS-overlay?

Thanks!



Yes, you may, but you have to aware that the GPS may not contain the LOC
station in its database. VOR stations should be fine.

And if that's the case you look at the little numbers on the approach
plate that give distances along final. That's also how you can
determine the MAP on a VOR approach when the VOR is located off the airport.
