     4.2  The specified Timing Gates will be positioned within this zone.
     4.3  Pilots must cross the top of the Timing Gates for both the start and finish of the program, at which point timing procedures will take effect.
     4.4  By majority consensus of the Chief Scorer, Contest Director and air show promoter at the briefings, competitors may commence the start of the AF part of the competition at an altitude not exceeding 1000m AGL

   5.  Timing Gates

     5.1  The timing gates will consist of pylons or flag poles;
       a.  Two sets of pylons that are a minimum 8 meters high,
       b.  Each set of pylons must be separated by between 25m – 30m,
       c.  The gate must be located along the X axis of the display line, 160m – 250m from the spectator line,
       d.  Flags may be attached to these pylons, ideally those representing the national flags of the competitors.

   6.  Signaling of start and finish of flights

     6.1  After receiving take off permission, pilots must climb to the designated holding point or to the display area according to tower instructions.
     6.2  The tower will give a radio instruction “Number 00 clear to start”, at which point the pilot is to approach the gates and be ready to commence his sequence at approximately 500m AGL.
     6.3  The pilot will notify the scorers of his intention to start by two distinct wing rocks or alternatively by way of a radio call, announcing “pilot start”.
     6.4  The start will commence once the aircraft has passed over the gates. Smoke is not permitted.
     6.5  The AAT sequence will cease once the aircraft has passed over the gates.
     6.6  To signal the end of the AF part of the program, the pilot is required to indicate the completion by two distinct wing rocks or by way of a radio call, announcing “pilot finish”. The pilot must then pass over the gates, with smoke on, at which point the timing will cease.
     6.7  After passing through the timing gate upon completion of the program the pilot must proceed directly to the landing runway and obtain landing instructions from the tower.

   7. Scorers

     7.1  At least three official scorers will be appointed by the contest director, one of them being designated Chief Scorer. These must be sanctioned and approved by CIVA.
     7.2  The flights will be timed from start to finish by the three scorers with the aid of chronometers.
     7.3  It is preferable that scorers are not selected from the same country as any of the competitors.

   8.  Evaluation of the competition flights

     8.1  The pilot’s score will be based on a time result derived from the combined program, and determined as follows;
       A.  Aerobatic Against Time program
i.  The total time recorded between start and finish
ii.  Penalties  in the form of time will be added:-
-  5.0 seconds for every “maneuver error” exceeding 20 degrees but not more than 45 degrees deviation from the stated figure.
-  25.0 seconds for every “no maneuver” error, no figure flown or a deviation exceeding 45 degrees from the stated figure.
-  5.0 seconds for “gate height” error, where the start or finish pass exceeds 7m above the gate height.
-  25.0 seconds for “low maneuver” error in the event that a pilot flies below the minimum altitude as prescribed at the daily briefings.
       B.  Aerobatic Freestyle program
i.  The total time recorded between start and finish. For the higher altitude start, from after the second wing rock at start to passing through the gate upon completion.
ii.  The scorers will individually give a score of between 0.0 and 10.0 as a “time bonus” for impression (originality, quality and difficulty).
iii.  The scorers will individually give a score of between 0.0 and 10.0 as a “time bonus” for technical (accuracy, competence).
iv.  The two scores will be added together to form the “time bonus”, which will be deducted from the total AF time. The “time bonus” will be the combined scores converted into seconds.
v.  A penalty for “elapsed time penalty” for either less than three minutes or more than three minutes, minus the one second allowance. Each second will be added to the total time.
vi.  5.0 second penalty for no smoke used at start gate.
vii.  5.0 second penalty for no smoke used during the sequence.
viii.  5.0 second penalty for no smoke used at finish gate.
ix.  5.0 seconds for “gate height” error, where the start or finish pass exceeds 7m above the gate height.
       C.  The total time will be the combined total of the AAT program and that of the AF program, less any further penalties.
i.  5.0 second added for “procedure and safety penalty” as adjudicated by the panel of scorers.
ii.  25.0 second added for each infringement of his lower waivered height limit for freestyle aerobatics, except for the purposes of passing through the timing gate.
   9.  Results

     9.1  The best placed pilot will be determined by the shortest aggregate time achieved after taking into account any penalties.
     9.2  The lower of the times achieved in the Competition Flight and the Final Competition Flight, by each pilot, will be taken into account to determine the winner of the overall competition.
     9.3  In the event that not all the prescribed days’ competition having being flown due to inclement weather, the results achieved from one competition flight will be taken into account to determine the final placings.
     9.4  Score sheets and time results will be distributed to pilots after each days flying.
     9.5    Ratings will be awarded to pilots for the purposes of competing in a series of contests, as follows
  1st place       10 points
 2nd place        8 points
 3rd place         6 points
 4th place         4 points
 5th place         2 points
