Plain English Meaning
A practice maneuver where the engine is at idle and the airplane glides down in tight, even circles around a chosen spot on the ground, with the pilot adjusting the bank to keep the circles the same size despite the wind.
Full Definition
A power-off, gliding maneuver in which the airplane is flown in a constant-radius descending turn around a point on the ground, using a bank angle that does not exceed 60 degrees at the steepest point. The pilot adjusts bank continuously to compensate for wind drift so the radius stays constant, and at least three full 360-degree turns are completed before recovery.
