The visual GA is a sensible thing, but it is not a feature over here- as far as I am aware, the official instrument GA is the only option available, and that is what most of us would expect to fly.
The Unstabilised Approach Criteria are pretty rigid, and if not lined up and stabilised by 500', we must GA. No ifs, buts.
Reviewing this thread- I got a lot of stick and abuse from people who thought I was wrong. I asked for one posting to be removed as it implied I was not safe to be near. And blow me down, who would we like to be flying a sidestep GA on one runway when someone is taking off on the other?
