http://220.127.116.11/d-tpp/0501/00927VD8.PDF Please look at this approach. I want to make sure I am understanding this correctly (as I have a lesson on it tomorrow). I find three (3) IAFs. Allow me to explain how they work, and please correct me if I am wrong. 1) The most obvious IAF is the VOR. From here, one proceeds outbound on R-215 to JONUR, and from there begins flying the ARC. There is no other transition from the VOR. (Look carefully at R-296--it isn't a transition to WILEN.) 2) WILEN is another IAF, located on R-269. How does one get there without GPS or RADAR? It turns out that R-269 is also V210, so you could have been navigating inbound on this victor airway. Turn right at WILEN to start the ARC. 3) JONJR is the other IAF. My question here is this: I can't see how one could navigate directly there without RADAR or GPS, unless you intercept R-215 early, outside of the ARC. There is no airway here, so I guess ATC could vector you on a heading to intercept that radial early. Whip out your ADF to make sure that radial is usable where (distance from the VOR and your alt) you want to intercept it. At JONJR, turn left to fly the ARC.Comments? Help with that last IAF? Thanks! Ben P.S. I'll try to look at responses before my lesson tomorrow AM, but if I can't I'll let you know how it goes, anyway!
