Definition
In the Eights on Pylons maneuver, the pivot is the point on the ground around which the airplane appears to turn when the pilot holds the wingtip aligned with a selected pylon. It is also used more generally to describe a fixed point about which an object or aircraft rotates.
Plain English
A pivot is the spot something turns around. In Eights on Pylons, it's the point on the ground that the airplane seems to circle while the pilot keeps the wingtip pointed at it.
Context Anchor
Used during the eights on pylons maneuver, when watching a selected ground point from the cockpit and judging whether it stays lined up with the wing.
Derivation
From the Old French 'pivot,' meaning a hinge pin or short shaft that something turns on. The aviation use keeps that same idea: a fixed point that motion rotates around.
Why Pilots Care
Correct use of the pivot keeps the turn radius constant so the airplane neither drifts toward nor away from the pylon.
Intuition Check
Do not read pivot here as a sharp spin or a fixed mechanical turn. In this maneuver, pivot means the ground point is used as the visual center of the turn.
Example Sentence 1
The pilot selected a tall silo as the pivot for the first half of the Eights on Pylons maneuver.
Example Sentence 2
At the correct pivotal altitude the pylon remained stationary, confirming the airplane was pivoting correctly around it.
