I'm a bit confused by the talk about confusion regarding overhead joins. What is confusing about an overhead join?
I agree a 45 degree join seems best when you already know the runway in use before you arrive at the airport; i.e., someone trustworthy told you on the radio. But if you do need to overfly the airfield, to check the windsock or whatever, the overhead join seems more straightforward and far quicker (lowering Pace's carbon footprint...
).
If I understand correctly a UK style OHJ means arriving overhead at 2,000 ft AFL? Then I can see why cloud base is a bigger problem; around here it is usually 1,500 ft AFL (when it is done at all), making it somewhat easier.
I'm astonished there are still ATC towers in operation in the civilized world that do not have radar and can not provide sequencing in the pattern...
