Air Control Points (ACP): The ACP i

Air Control Points (ACP): The ACP is a topographic feature that is easily identifiable from the air that can be used as a navigational aid. It is normally located at each point where the flight route changes direction. However, a flight route can contain, as many ACP's as necessary to control the air movement.Intercept Headings: The heading from the RP (or CCP if the Pathfinders do not use an RP) to the landing site coincides as closely as possible with the landing direction to keep the helicopter from having to turn sharply. The larger the formation, the more important this becomes. If a pilot cannot approach the landing site straight on, Pathfinders will set up an intercept heading. They choose an intercept point far enough from the touchdown to allow helicopters in formation a final approach of at least 1 to 2 miles.
