RE: To Rule, or Not To Rule?
Contrary to popular belief, more rules does not mean safer. Nor do more rules make it work better.
That all being said, about the only thing that needs to happen is that all persons at the site on any given day agree on which system to use. Put a bord up, red for no impound and white for impound in use; or some such.
I fly in places where there is no impound, where there is an impound, and places where there is no impound or frequency board. We talk.
If you find a better way, please share it.
