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.

Thick dot represents the beginning of the manoeuver, while a short perpendicular line represents the end. A roll symbol that starts at the line denotes a half roll see description of the Immelman. This maneuver is sometimes called a hammerhead stall. The plane symbo,s flying throughout the maneuver with all the control surfaces effective although sometimes only marginally so.
Aerobatic competitors fly three “sequences” at each contest. Aileron rolls are flown with the rudder and elevator in the neutral position during the roll. For the purposes of this book, competitive aerobatic flying and display flying are gathered into one discussion.
Figure 4 is a tailslide with the wheels up inverted during the flip. At symmbols advanced stage, the maneuvers come rapidly, one after the other, so it becomes more important than ever to exit each maneuver properly symbolss you can move directly to the next. Parts of loops connect these line segments.

Commons category link is on Wikidata. This trades speed for altitude. Five-eighths of a loop complete the figure to horizontal flight. These symbols may look complicated at first, but a careful inspection reveals that they are very descriptive of the maneuvers they represent.
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. This is another variation of the basic loop. The maneuver starts with a pull-up of about 3 to 4 G.
Figure 1 shows symols symbol for a regular inside snap roll. These descriptions are NOT intended as instruction. Past the top, the back pressure is slowly increased again throughout the back part till horizontal flight.
In this figure in competition the two looping parts have to be flown at the same altitude with the same radius. The figure starts with a quarter loop to a vertical climb. Solid lines describe upright flight, and dashed lines describe inverted flight. The idea is that this is a “plan ahead” maneuver. syjbols
But this broad term includes many other smaller categories of flying, including stunt flying, competitive aerobatics, and display flying. In this case it trades altitude for speed.
In Aresti, each maneuver has its own symbol. He devised the system to help keep track of maneuvers in international aerobatic competition.
By the end of Aresti published a dictionary of some 3, aerobatic manoeuvers, the Sistema Aerocryptographica Aresti. Figure 2 shows an outside snap. When the plane stops climbing, it pivots around its vertical axis which is now horizontal.
All aerobatic figures start and end from horizontal lines in either upright or inverted flight. The pivot is stopped with opposite rudder when the nose points straight down.
Once the bank is established the turn is started. Archived from the original on 3 March The figure completes with another quarter loop to horizontal flight. By combining these symbols, you can form logical sequences. Wikimedia Commons has media related to Aresti-Symbols. The plane should not settle during the last part of the maneuver and the recovery. 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.
The exit line at the bottom has to be at least as long as the other seven sides. The elevator is then neutralized and the aileron fully deflected areti the direction of the roll.
They all involve flying a number of maneuvers in a sequence, but have different results. A roll symbol that crosses the line specifies a full roll first figure. Hesitation or point rolls include stops at certain roll angles. These maneuvers involve bringing the airplane to a complete stop in a vertical attitude and then sliding back a visible amount.
The catalog broadly classifies manoeuvers into numbered families.

It has to be perfectly round, entry and exit have to be at the same altitude. Then employed throughout Spain, the Spanish Aero Club urged its adoption internationally. The looping portions in almost all figures have to have the same radius in all parts of a figure.
Use the Aresti system to write down the maneuvers; this arestk helps in practice and makes a record of your maneuvers for later reference.
