Hi Jim,
Thanks for attempting to answer my question. I'll try to be a bit more clear as I doubt I described my problem clearly.
- I do know about the option to see airports with runways greater than a certain length. I, too, don't recall what the default value is. But this isn't my problem.
Usually when selecting the DEP/ARR key one usually gets a selection of runways on the Right Soft Keys (RSK) and, in most cases, SIDs or STARS on the LSKs. With the default ORD and, when I used it, with a modified AFCAD downloaded from one of the freeware servers, the runways did show up upon arrival or just before departure when planning the flight. With the FSDT ORD, no runways are recognized when the DEP/ARR key is depressed. I wondered if anyone else on this forum had a similar problem as this.
All other, at least known to me, airports behave more predictably when this key is depressed. And my old AFCADs (and the default one too) also worked fine with the PMDG 744's FMC. This isn't too big of a deal as I program, manually, the waypoints on the approach charts upon arrival, but I thought this should feature should work since it has in the past for my other ORDs that I had used. I did delete all other AFCADs that I had in-use before installing the FSDT ORD.
Again, Jim, I do appreciate your reply!
