Hi,
do you mean the dme distance with wrong read outs? What aircraft has you use?
I have tested the VOR15 approach with the standard stock A320 (Navigraph AIRAC 2205 installed, stock scenery) and the DMEs are all absolutely correct.
approaching KORAX at SNI/9.0
final MA15, SNI/2.0:
I can´t see any DME readout issues here sorry.
Cheers
Richard
