Aresti’s fundamental insight was that almost any aerobatic figure can be broken down Pingback: Aresti Notation (aerobatic symbols) | The Aerobatic Project. EXPLANATION OF ARESTI SYMBOLS. Beginning of flight. | End of flight. Inside loop (positive G). Start of manoeuvre. Outside loop (negative G). First published in , José Luis de Aresti’s ‘Sistema Aresti’ provided Aresti Notation (aerobatic symbols), Part 1: the Standard Known.

In Aresti notation, solid lines represent upright or positive-g manoeuvers and dashed lines represent inverted or negative-g manoeuvers; these are sometimes depicted in red. The figure starts with a quarter loop to symbole vertical climb.
This is a variation of the basic loop. This maneuver combines a turn with rolls.
The exit has to be at the same altitude as the entrance to the figure. The downline can be used to adjust the altitude and speed at the end of the figure. The catalog broadly classifies manoeuvers into numbered families.
The nose then keeps dropping below the horizon and the plane keeps turning, while the bank is shallowed. Archived from the original on 26 March No pilot should attempt to fly any of these figures in aircraft not certified for aerobatic flight. This figure also is the second half of a loop downward, this time an outside loop.
Solid lines describe upright flight, and dashed lines describe inverted flight. This one, like the Immelman, does not preserve speed and altitude. In this figure in competition the two looping parts have to be flown at the same altitude with the same radius. This section will focus on learning sequences of maneuvers designed to improve your flying skills and, more important, showing your flying skills and the capabilities of your computer and software.
When the plane is vertical, the elevator back pressure is released completely. You pull up and at the same time bank the plane. There are some figures where this does not apply completely. The airspeed may be very low, close to zero, but since there is no wing loading during the turn-around, there is no stall at zero g wing loading, a wing does not stall. When the plane stops climbing, it pivots around its vertical axis which is now qresti.
The plane has to maintain a constant roll rate, constant turn rate and constant altitude throughout the rolling turn. As drawn, the figure depicts a quarter roll flown on a vertical up-line.
Putting together several maneuvers is called sequence flying.
This is another variation of the basic loop. Once the rotation has stopped, a vertical downline has to be established.
The aileron is fully deflected in the direction of the roll. Basic Sequence 1 is a descending sequence, so start at a great altitude. A Chandelle to the left is quite different than one to the right because of the ever increasing amount of p-factor in the second half of the maneuver. This is the easiest of the rolls to fly.
After the roll is completed the nose is usually 20 – 30 degrees below the horizon. In both cases rudder is then used to start autorotation just like in a spin. Archived from symbls original on 3 March The plane should not settle during the last part of the maneuver and the recovery. The aileron roll is started by pulling the nose up to 20 – 30 degrees above the horizon. Retrieved from ” https: Higher K-values areesti more difficult maneuvers.
Once you’re familiar with the whole routine in small groups of maneuvers, you can put them together in a sequence. The maneuvers shown in this section are by no means the only ones you can perform. Practice at this point is prohibited, and pilots are faced with the symbo,s of flying a brand new combination of figures without rehearsal.
The rotation has to stop exactly after the specified number of turns. This is a detailed explanation of how to properly execute a Half Cuban Eight to the judging standards of competition aerobatics.
This again is one of the maneuvers that have been used to reverse direction while preserving altitude and airspeed. These maneuvers involve bringing the airplane to a complete stop in a vertical attitude and then sliding back a visible amount. The next, the “free,” is a sequence unique to each competitor.
A brief primer on the basics of Aresti notation is given below. The turn needs to be kept coordinated by applying the right amount of rudder. The aileron and barrel rolls are not flown in symbops competitions. The quarter loop is flown just like the first part of a loop.
