In the past this was known as the <i>Q</i> (for <i>qualifying</i>) program.</li> <li><i>Free Known</i>: At FAI championships each pilot integrates 5 'Known' figures with 5 of their own that are freely selected from the Aresti Catalog so that together the 10 figures meet the specified overall versatility and total-K (difficulty) requirements.</li> <li><i>Free</i>: In this program, each pilot is given the opportunity to demonstrate his personal flying skills, creative talent and his aircraft performance by designing his own sequence.</li> <li><i>Unknown</i>: This program is made known to the contestants only about 12 hours before the competition. The figures are chosen by either teams or pilots, each submitting a single figure. Under CIVA rules pilots fly up to three Free Unknown sequences (see below). In Local contests often the governing body or the contest chief judge choose the unknown sequence. The pilots must not practice before flying the unknown sequence. (For classes Intermediate and above.)</li> <li><i>Free Unknown</i>: Teams or pilots together select 10 figures (7 for gliders) that they must all use in a similar fashion to the <i>Free Known</i> system, adding up to 4 additional figures (2 for gliders) that are employed principally to reposition or turn-around the aircraft to ensure smooth continuity of the whole sequence.</li> <li><i>4-minute Free</i> or <i>Final Freestyle</i>: Only the top unlimited pilots might be invited to fly this final program. In this program pilots strive to display their creativity and superior skills as performers, the judging here being almost entirely subjective as opposed to objective assessments of figures according to the Aresti system as used for all other programs.</li></ul> <div class="mw-heading mw-heading2"><h2 id="Aerobatic_box">Aerobatic box</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Competition_aerobatics&amp;action=edit&amp;section=3" title="Edit section: Aerobatic box"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure class="mw-default-size mw-halign-right" typeof="mw:File"><a href="/wiki/File:Aerobatic_box.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Aerobatic_box.svg/376px-Aerobatic_box.svg.png" decoding="async" width="376" height="332" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Aerobatic_box.svg/564px-Aerobatic_box.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Aerobatic_box.svg/752px-Aerobatic_box.svg.png 2x" data-file-width="376" data-file-height="332" /></a><figcaption></figcaption></figure> <p>The aerobatic box is a volume of airspace in which the aircraft must remain while performing a sequence. Its length and width are each 1,000 metres (3,280&#160;ft). Its height varies based on whether FAI, national aero club or local rules apply to the competition. White ground markers at each corner of the box make it visible to the pilot from the air. For most categories, penalties are assessed for flight outside the aerobatic box. </p><p>The box has two axes, the identification of which is based on the location of the judges. The X-Axis (called the A-Axis by some aero clubs), runs across the line of sight of the judges. It is along this axis that most figures are usually flown. In some contests a center line is marked along the middle of the X-Axis. </p><p>The Y-Axis (called the B-Axis by some aero clubs) runs perpendicular to the X-Axis, toward and away from the judges. This axis is used for cross-box position correction. The official wind direction is always declared by contest officials to be along the X-Axis. This, however, does not always reflect reality, and generally during the course of a sequence the competitor will drift either toward or away from the judging line. The competitor can extend or shorten maneuvers flown along the Y-Axis to obtain the desired positioning. </p><p>The box floor is as high as 460 metres (1,510&#160;ft) above ground level (AGL) for Primary level competitors and as low as 100 metres (328&#160;ft) AGL for Unlimited level competitors. The box ceiling is as high as 1,000 metres (3,280&#160;ft) above its floor. Before a category starts, a competitor will mark the box by flying along its boundaries at its floor. This allows the judges to visualize the box in the sky and prepares them to adjudge an aircraft flying below the box floor. </p><p>At a groundspeed of 300 kilometres per hour (190&#160;mph) the pilot has 12 seconds from entering the box on the one side before exiting the box on the other. </p> <div class="mw-heading mw-heading2"><h2 id="Judging">Judging</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Competition_aerobatics&amp;action=edit&amp;section=4" title="Edit section: Judging"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Arestisequence.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/7f/Arestisequence.png/200px-Arestisequence.png" decoding="async" width="200" height="307" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/7f/Arestisequence.png/300px-Arestisequence.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/7f/Arestisequence.png/400px-Arestisequence.png 2x" data-file-width="532" data-file-height="816" /></a><figcaption>An aerobatic sequence in Aresti notation.</figcaption></figure> <p>Each category within a competition may have between 3 and 9 <i>grading judges</i>, each of whom is accredited by the contest's sanctioning body. They are positioned between 150 and 250 metres (490 and 820&#160;ft) back from the edge of the box, at the center of the X-Axis and facing that axis. Each grading judge is assisted by an <i>assistant judge</i>, who reads <a href="/wiki/Aresti_notation" class="mw-redirect" title="Aresti notation">Aresti notation</a> and verbalizes to the grading judge each figure to be flown, and if possible also a <i>recorder</i> (also called a <i>writer</i> or <i>scribe</i>), who records the judges marks and comments, commentary and ancillary information on a competitor's score sheet. For some flight programs, a single individual may serve concurrently as assistant judge and recorder. </p><p>A grading judge assesses the quality of each figure flown according to well-defined criteria and assigns it a numerical mark in steps of 0.5 between 0 and 10. Under FAI and some national aero clubs' rules, the judge may also assign a mark of "Hard Zero" to indicate that the wrong figure was flown, or a "Perception Zero" if a mandatory though subtle element of the figure is perceived to have been missing. At the conclusion of each flight, the grading judge assigns a Presentation or Positioning mark based on the competitor's placement of figures within the aerobatic box throughout the sequence. A grading judge also determines if the competitor has flown below the floor of the box or above its ceiling. Each grading judge is further charged with assessing whether a competitor is flying safely and advocating for the competitor's disqualification if not. </p><p>A <i>chief judge</i> oversees the operation of the judging line. He or she is often responsible for sequencing competitors into the aerobatic box, identifying and resolving judging and safety issues, reviewing the judges marking sheets, assessing penalties, monitoring the aerobatic box for traffic conflicts, conducting briefings for pilots and judging line personnel, and certifying scores. A chief judge is typically assisted by 2 or more individuals. In some competitions, a chief judge may concurrently serve as a grading judge. </p><p><i>Corner judges</i> (also called <i>boundary judges</i> or <i>line judges</i>) may also be used and are positioned at the edge of the buffer zones, 50 metres (160&#160;ft) along each axis beyond marked corners of the aerobatic box. They monitor and record each excursion beyond the buffer zone; the competitor earns a penalty for each such excursion. Each corner judge guards 2 of the 4 lines that define the box. In most competitions, 2 corner judges are used, located at opposing corners. Two judges guard each line; they must agree that a competitor has crossed a boundary in order for the competitor earn a penalty. In FAI championships more accurate electronic feedback systems are required to provide a constant measurement of the aircraft position, and hence its excursions beyond the buffer zone if these occur; if such equipment is not available this task is confined to the judge's position grade. </p><p><i>Deadline judges</i> may be positioned along a deadline, if one has been established by the contest's sanctioning body. They monitor and record each infringement of the deadline. The competitor earns a penalty for each such infringement, that penalty being more severe than an excursion out of the aerobatic box. </p> <div class="mw-heading mw-heading2"><h2 id="Judging_downgrades_summary">Judging downgrades summary</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Competition_aerobatics&amp;action=edit&amp;section=5" title="Edit section: Judging downgrades summary"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Here is a précis of the principal "faults" that you should look for and the number of marks to deduct whilst you are applying standard CIVA rules of critique to sequence programmes at all levels. </p> <div class="mw-heading mw-heading3"><h3 id="At_the_entry_to_and_exit_from_every_figure_element">At the entry to and exit from every figure element</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Competition_aerobatics&amp;action=edit&amp;section=6" title="Edit section: At the entry to and exit from every figure element"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <table class="wikitable"> <tbody><tr> <th>Horizontal start &amp; finish lines </th> <th>Deduction </th></tr> <tr> <td>Off axis left or right n-deg</td> <td>1 point/5 deg </td></tr> <tr> <td>Climbing or diving n-deg</td> <td>1 point/5 deg </td></tr> <tr> <td>One wing low n-deg</td> <td>1 point/5 deg </td></tr> <tr> <td>No distinct line drawn</td> <td>1 point each </td></tr> <tr> <td>Flying in wrong direction on the "A" axis</td> <td>Mark = Hard Zero (HZ) </td></tr></tbody></table> <div class="mw-heading mw-heading3"><h3 id="Family_1_-_lines_and_angles">Family 1 -
