Thanks folks.
Eastern Wiseguy, why would you use a VOR/DME rather than an ILS approach? Presumably, a VOR/DME can only be used when final approach is in visual conditions? I'm guessing that a VOR/DME with an OBS of 252 gets you roughly in line with the runway at BFS. Then when visual, you can line up properly. Why would you do it this way rather than flying the ILS?
This stuff fascinates me, so please excuse my ignorance!!
