Cardinal Rule 1
Arriving Aircraft will not be given clearance to land at a landing point until all preceding A/C have taxied from or flown forward of designated landing point.
Cardinal Rule 2
Departing A/C will not be cleared for departure until all preceding A/C have flown clear of the forward landing point. This is to prevent one A/C from over-flying another.
Cardinal Rule 3
Never allow a Sling Load A/C to fly over personal, equipment, or another A/C at any time.
