Rex Havoc,
What is simple is that you made the statement in a post directed to me that;
Intersection departures when properly calculated, do not reduce the safety margin.
That statement is factually incorrect. Simple.
You can spin it with stats and likely hoods but it's still wrong.
How many times have you or someone you've known over-run the shorter of two runways? One in a million?
See, the low occurrence count doesn't diminish the point.
