If you
overflew UBG for 5 miles and then turned back to UBG, would that make the
approach legal to fly?


Lake Placid, NY, has these types of restrictions on their GPS approaches.

Upon preparing for the flight to LKP a few years ago I had seen the note on
the above chart and asked a more experienced IFR pilot about it. He told me
that these types of notes are common when the required course direction
change after the IAF is too great. TERPS doesn't want aircraft making that
large a course change in the clouds, presumably in this case due to the
nearby mountains.

I was told that if you do not have the option to choose a more aligned IAF
based on arrival direction (and that radar vectors are not available), then
file to a VOR, intersection, or GPS fix that does provide a more direct
arrival to the IAF and plan on jumping off the airway sooner to fly direct to
that point.


And sometimes they just get it wrong.

shows such a restriction, but the NA from VOLAN is backwards. Should
read approach NA from VOLAN eastbound, not westbound.
