Chandelle The Chandelle is not used in aerobatic competition. On the FAA power commercial pilots test a Chandelle is defined as a maximum performance climbing turn through degrees while maintaining a constant turn rate. The idea is that this is a "plan ahead" maneuver. You first establish a medium bank depending on the performance of your aircraft. Then a smooth pull-up is started.

The entire list of figures is shown in the current "Aerobatic Catalogue," originally adopted in Credit is given in that publication to the "valuable suggestions and improvements proposed by Sr. Jose L. Aresti of Spain and Mr. Eric Muller of Switzerland. The first, called the "known," is a combination of maneuvers chosen at the start of each year and thereafter flown by every pilot at every contest. The next, the "free," is a sequence unique to each competitor. Here pilots have the option of choosing maneuvers and combinations best suited to their individual skills.

The last, the "unknown," is handed to competitors half-way through the contest. Practice at this point is prohibited, and pilots are faced with the necessity of flying a brand new combination of figures without rehearsal.

A brief primer on the basics of Aresti notation is given below. For a more detailed insight, see the graphics accompanying each individual maneuver listed on the aerobatic courses page. A small circle at one end of a figure indicates the maneuver starting point.

A short vertical line at the other end of the figure indicates the maneuver end point. Horizontal segments represent level flight paths flown left to right in this example. Vertical segments indicate vertical flight paths. Dashes used to draw lines indicate inverted flight negative G.

Circles and portions of circles indicate loops and loop portions. Short arcs approx. Portions of arcs approx. As drawn, the figure depicts a quarter roll flown on a vertical up-line.

Right triangles indicate spins. Equilateral triangles indicate snap rolls. Hammerhead Turn.

Understanding Aresti figures in Aerobatic competition How do pilots know what aerobatic manoeuvres they have to fly when they compete? The answer lies in understanding what are called Aresti figures. Named after Jose Aresti , a Spanish aerobatics instructor who developed them in the s, they use a system of lines, arrows, geometric shapes and numbers to describe the precise form of a manoeuvre. The system allows pilots to understand what is expected of them in training or competition, and it also allows pilots to invent new figures.
