VOR Arrival plate Question
I have a arrival plate for XXX airfield. the approach is a VOR RW34.
It is written with no DME information. The minimum height over the VOR is 2000ft. The platform altitiude is 1600ft. There is a notional DME distance of 18 (no reference to what aid this is from) with regard to when this turn must be made by (prevent hitting a mountain I guess).
I take it I can turn beacon inbound and subsequent decent when I am confident of safely intercepting the path, not lower than 1600ft and not beyond 18 miles. So if 1600/3 is say 5.5, would you consider turning in at say 8 miles from when VOR beacon outbound?
