When the succeeding aircraft is a helicopter or powered‐lift aircraft, visual separation may be applied in lieu of using distance minima. (3-9-6a5, 3-10-3a3)

These are the order's minimum distances, for when distances can be determined by reference to suitable landmarks. Each links to its line of the 7110.65, which has the conditions. Wake turbulence separation is applied separately.
