reporting an issue with LOWK/Klagenfurt.
The airport features several RNAV STARs that all terminate at MOKEG, no matter what landing direction is in use. From MOKEG there is either a MOKEG2E RNAV transition for ALL approaches (ILS + RNP) for runway 28R or MOKEG1W RNAV transition for RNP 10L.
In X-Plane and FSX/P3D, using different addons (Zibo 737, Jehell A320, Aerosoft A319) those RNAV transitions are only available when selecting one of the RNP approaches, although MOKEG2E also needs to be available when going for the ILS approach runway 28R. MOKEG2E terminates in WK827, where either the RNP 28R or ILS 28R begin.
My suspicion is that the ILS 28R does not feature MOKEG2E, because on the chart it begins at KFT VOR. If you look closer, you will see a note below the VOR description saying “WK827 on RNAV transition”.
In conclusion, your navdata/procedure data needs to be amended to make MOKEG2E available when selecting ILS 28R.
All the best, Andreas
