Plain English Meaning
Pressing the rudder pedal on the opposite side from the way you are turning. In a left turn, that means pressing the right rudder pedal; in a right turn, the left rudder pedal.
Full Definition
Rudder pressure applied on the side opposite the direction of turn during a maneuver, used to correct for a pylon that appears to be moving ahead of the wingtip reference during eights-on-pylons. Outside rudder yaws the nose away from the pylon, which lowers the wing slightly toward the pylon and re-establishes the correct sight line.
Context Anchor
Seen in ground reference maneuvers such as eights on pylons, where small rudder inputs affect coordination and how accurately the airplane tracks around the pylon.
