Thanks, Habu2u2, for your input. Meanwhile I found, that the ILS approach in APR mode for one single RWY at the same airport is not always misaligned. Yes, it’s curious.
My recent observations lead to the assumption: Depending on how I do the flight planning the results of an ILS approach hitting the RWY center line correctly are different. For flight planning I’m using:
- standard world editor from the main page
- route and approach input directly to the GPS
- route and approach input by the aid of an external flight planning program e.g. “little navmap”
So far it seems to me, as if only 1. works as it should: Touch down at the RWY center line.
In all 3 cases the LOC gives the correct signal to the HSI which can be seen from the CDI needle. Manually flying the CDI needle and decending on the GS indicator would give a correct RWY arrival.
to be continued . . . .
