Hello

a question again;-)

Our PA34 with two Garmin GNS430 is certified for B-RNAV (RNP5)
I can't find any information about the source signal.
Does the GNS430 calculate RNAV information only from its GPS-signal or can
it also get information from the VOR/DME?

Does anybody know something about that?

Thanks a lot.

Daniel
