pylons

eights-on-pylon (pylon eights)

A maneuver involving flying the aircraft in a circular path alternately left and right in the form of a figure 8 around two selected points, or pylons on the ground. The distance from the pylons is not uniform. Instead, the aircraft is flown at such an altitude and air speed that a line parallel to its lateral axis and extending from the pilot's eye appears to pivot on each of the pylons. Also called eights-around-pylons and around-pylons-eights.
