Hi, OzEx I thought you'd get here sooner or later!
Yes, as far as the 30 deg either side goes we're all reasonably clear. You didn't address the other situation though - possibly deliberately. If you are close to the o/b leg of the procedure (but not on it) and would have to go out of your way to get back to the IAF (and then most likely have to turn around again to go o/b) why shouldn't you manoeuvre above MSA to establish somewhere along the o/b leg, and then descend to the the procedure altitude(s)?
Jambo and I seem to agree that there's nothing unsafe about that, but is there any prohibition in the legislation?
