A Question on Navigation:

I just flew from KAVP in Pennsylvania to KUNV (University Park - Home of Penn State)using the DF Cardinal and an IFR flight plan made with the FS flight planner. While using the FS9 ATC it cleared me for a radar vector approach to the ILS rwy 24. I decided to try a different approach and selected the full ILS 24 approach for practice. The menu prompted me to select either the Tyrone or PSB (Philipsburg) transitions. I was comoing from the east, and upon viewing the ILS Rwy 24 plate I noticed the PSB and Tyrone vors are west of the airport. There is no transition near or along my path from the east. Do real pilots have to fly out of their way to the west in this case to pick up the approach, or is there a missing transition? The plate shows RASHE to the south which would be more convenient for me, but there was no choice for it. Thanks. Tom
