The idea is to do two circular manouevres, one above the other, with both having the same radius, directly in front of the pilot's stance. The central part of the manouevre is the crossover.

The Vertical Eight shown has no included rolling manouevre and so the bottom loop of the Eight is an inside Loop while the upper part is an outside loop or Bunt. Generally, the Vertical Eight is executed while heading upwind.

A common variation of this is to incorporate half rolls at the crossover in both the ascending and descending parts of the eight. This results in both parts of the Eight being inside loops.

The Gold schedule includes a Vertical Eight but unusually this begins and ends in the middle. In fact, this variant is simply a Loop followed by a Bunt on the centreline which should be clear from the diagram.
