Practical IFR: Mix and Match
As an aviation writer, I’m always on the prowl for interesting approach charts (so if you have a favorite, drop me a line). One that recently appeared in my email was the ILS or LOC Rwy 27 at Williamsport, Pennsylvania (KIPT). The striking curiosity was plan view note, “RNAV 1-GPS or RADAR AND DME REQUIRED.” The investigation yielded a longer explanation than I expected. Too bad I don’t get paid by the word.
