constant-pressure-pattern flight

A technique of pressure-pattern flight whereby an aircraft is navigated, in the direction of wind flow, along a height contour line on a constant-pressure surface, thereby assuring a continuous, nearly direct tailwind.

This is accomplished by maintaining constant indicated altitude on the pressure altimeter along with constant absolute altitude above a level surface. The latter requirement restricts the use of this method to over-ocean flight.
