The format of all international aerobatic championships was changed at the CIVA 2015 plenary conference in Budapest, where the commission voted to introduce a new programme 1 called the "Free Known". This replaces both of the long standing Known/"Q" and Free programmes, #1 and #2. The range of compulsory unknown programmes that follow was extended to maintain the same number of sequences to be flown at each event.

**Why has CIVA done this?**

The initial programmes at CIVA aerobatic competitions have remained almost unchanged since the first FAI World Championship at Bratislava in 1960, all competitors flying the same CIVA approved 'Known' compulsory sequence and subsequently a 'Free' sequence composed by each pilot to meet standard regulations. Over the years at power events the Known became the "Q" (qualification) programme, originally with the scores discarded upon completion of the subsequent programmes, and the Free programme even passed through a 'bonus' phase that entitled sequences with less figures to benefit through a percentage-based bonus factor. Eventually however it became clear that the Free sequence offered competitors too much opportunity for the construction of over-simplified solutions, and overall these two initial programmes had become insufficiently challenging - the subsequent Unknown programmes providing the real test of a potential champions' skills.

**How does the 'Free Known' programme work?**

For each power and glider category five 'Known' master figures are now selected by plenary and published each year. Each of these may be used in any order and any orientation at any position within the sequence, though their design must remain unchanged. Each pilot must add five 'Free' figures to design their personal 10 figure Free Known sequence. Overall the sequence must conform to regulations that define the versatility required and the maximum K allowed. Every pilots Free Known sequence can thus be different, and of course must change each year to incorporate the annually revised sets of five Known master figures.

The figures for 2017 are shown below. Remember that the sequence -

- must not exceed the given maximum K values
- must satisfy the the relevant programme versatility rules

Pilots must ensure that the five Known figures A-E are clearly identified when submitting the OpenAero or Visio Aresti computer file for an event. This is to facilitate checking by the organisers and subsequently to ensure accurate transfer of the sequence data into the scoring system.

§ As is usual for glider programme-1 the sum of the normal figure coefficients may be as large as 233 (“AG” 178), but will be reduced to 230 (“AG” 175), starting with the highest value, by removing one point from the highest coefficient figure that has not had a point removed. On judging forms the original figure coefficient will be given as well as the reduced value.Free |

Other important information that the Section-6 part 1 regulations will provide for power events are:

- Before the wing-dips to start their Free Known sequence, pilots are entitled to fly the normal warm-up two half-rolls plus for this programme up to
__three__of the other published warm-up figures plus up to the__first five__of their own Free Known sequence figures. - The usual minimum height penalties will be awarded if required.
- The time limit for programme 1 remains 10 minutes from lift-off, at which point the Chief Judge will call "Time, time, time" and figures performed after this will not be marked.

The new 2016 Section-6 part 2 Glider regulations are now published (*see the Document Store page*), the part 1 Power regulations being finalised as this item is written. These will provide the regulatory structure to be applied at all CIVA international championships.
