José Louis Aresti split aerobatics down into a basic code system - rather like music notation - so that others could communicate universal manouevres. Each part of the "code" is rated for difficulty - the 'k' factor - so that the difficulty of a complex manouevre can be assessed and judged. All manouvres are marked by judges out of ten and the overall score is calculated by multiplying the judges mark by the 'k' factor
All manouevres have a start point, an end point and pull positive or negative "g" forces.
Aresti codified these as:
| The start point is a small circle |  |
|
| The end point is a short vertical line |  |
|
| A solid line represents positive "g" flight - upright |  |
|
| A dashed line represents negative "g" flight - inverted |  |
|
| An unfilled triangle represents a positive "g" manouevre |  |
|
| A solid triangle represents a negative "g" manouevre |  |
|
| A number represents the difficulty of the manouvre |  |
|
| Putting these together gives the Aresti Diagrams for upright and inverted flight. Note that inverted flight has a slightly higher 'k' factor than upright flight . If you score 8/10 for an upright pass and 6/10 for an inverted pass, you will actually collect more points for the inverted pass - 6x3 rather than 8x2. It should be clear then that it's better to score average points on the tough manouvres than above average on the easy ones - don't completely mess up the manouevres with "k=30"! | ||

| Moving on to rolling manouvres, a full roll is indicated by a curving arrow. |  |
|
| The half roll is a special case as it is usually used for rolling inverted or upright as part of many other manouvres. It is designated by a curved arrow which is only drawn above the line of travel. | |
|

 |
||
| A 360° roll can have hesitations or points inserted throughout the rolling manouevre and the normally recognised points are 2, 4 and 8. Again, the roll is designated by a curving arrow, the number at the bottom indicating how many hesitations a full roll would be broken up into. The "fraction" at the top of the arrow indicates how many of these hesitations are to occur. A nice variation of the half roll to inverted is the 2 of 4 point roll where a hesitation is inserted - just to check that you know what the rudder is for! |  |
|
 |
||
| Looping manouevres are self explanatory, the solid line indicating the flightpath. |  |
|
 |
||
| In a stall turn, the 180° rotation at the top is indicated by a short curved line. Although the start and end points are shown at different levels - for clarity - they should be at the same height. |  |
|
| A "standard" spin is a positive "g" manouevre so an unfilled triangle (or triangles) are used to indicate the number of turns. Normally the number of spins is one or two. |  |

These are the most basic manouevres commonly used and, where applicable, we will show them throughout our Aerobatic Guide.
