Tee hee...yep, as I said: confusing.
Try googling 'definition of "alternate minima"'.
It's a long and convoluted subject.
I believe I am basically correct for the rest of the world. As for Australia it may depend on your background - ie RAAF, International, or G/A.
Maybe I'm just confusing things dipping into the Oz question but I'm finding it quite interesting. As I say - I'm looking at it from an international operaters point of view and of course do stand to be corrected!
