Ok guys lets not point score here.
Never heard the term General Air Traffic and I've been flying for over 20 years. I assumed and gave you the benifit of the doubt that you meant General Aviation.
My guess is that General Air Traffic is what it says. Just that. Maybe you could tell all? Is it an ATC term?
As for absolute minima, it would never affect the majority of flight deck as they never go below minima anyway.
