24.1 DME arc not so bad!
A little thread drift, but it might interest GF and possibly Bloggs, that in the early 70s, Toledo Express Airport, like Wallops, had a TACAN arc as the final segment for RWY 25 that the Guard F-100s used routinely.
I believe it was a 10 or so DME arc
, don't remember the minima. Flew it once coming over from Columbus.
The chart is long gone. It was cancelled after the Toledo Guard crashed one on the approach.
If you look at Hutchinson, KS, there are VOR, ILS and LOC approaches with DME arcs to final, but the NDB is a simple PT, no other requirement than ADF capability. End of an era. If you're flying NDB over here these days it's probably only because you can't afford much else for your puddle-jumper.
edit: BTW at the time the TOL Tacan wasn't at the field or the approach was off of Waterville.
