Eights on Pylons - Overview Ground reference Maneuver

 

Eights on Pylons - Visual Clues

The maneuver "Eights on Pylons of" is part of ground reference training, focusing on wind awareness and smooth control at low altitudes. The aim is to circle two points on the ground in a figure-eight pattern while keeping a constant visual reference of the points at a specific altitude.

The key element here is pivotal altitude, which is the height where an object on the ground stays fixed relative to your aircraft's wingtip during turns. The formula for calculating this altitude is:

Pivotal Altitude = (Ground Speed^2) / 11.3

For practical purposes, starting around 900-1000 feet AGL usually works well. As your ground speed changes throughout the maneuver, the pivotal altitude will fluctuate slightly. The pilot adjusts the aircraft's attitude by increasing or reducing elevator pressure to maintain the pylon's position on the wingtip.

Mastery of this maneuver, like any flight skill, requires systematic practice. It helps sharpen overall piloting skills, especially useful when preparing for your CPL check ride.
