Milt,
Flying in the northern hemisphere often puzzled me as I found I was less able to instinctively know where north should be
I always thought it had a lot to do with the fact that the sun in in the northern hemisphere is always ever so slightly to the south as it transits through the sky - vice versa in the southern hemisphere.
So when you are walking flying northwards in Oz, you are flying towards the sun... if flying northwards in the UK, the sun is behind you (assuming the sun is out, and not covered by clouds)
