Thank you, Keith for explaining the FAI system. I would like add the following extracts of the current FAI Sporting Code 2012, Volume F2 Control Line Model Aircraft:
re Practice Circles: Annex 4F Control Line Organizers Guide Page 86
6.5.2.5.
At World and Continental Championships and other limited international contests, organisers shall also provide Practice Circle/s. These shall be located at the contest site itself, but in any event shall not require more than 30 minutes of normal travelling time to reach from the contest site. Organisers should provide a minimum of one Practice Circle for every 50 registered contestants. All Practice Circles shall be freely open and available for use by all contestants for at least the duration of the contest, plus also for a suitable time before the start of the contest. All Practice Circles should be as close as possible to the standard and maintenance conditions set out at paragraphs a) and/or b) above; but except for the marking of the centre of the centre (pilot’s) circle and the outside diameter circle, the marking of circles as described at paragraph c) above shall not be required. However if the Practice Circle/s site is open to public access then organisers shall also erect suitable safety barrier/s and warning signs in the local language.
re Judges Qualification / Selection: Annex 4B Class F2B – Judges Guide Page 59
Judges' Qualifications and Selection of Judges for Contests
The National Aero Club (NAC) of each country having F2B judges who join (or who wish to join) judging panels at international F2B contests should ensure that a defined standard of judging proficiency is reached and maintained by each of the judges for which it has responsibility. Each such NAC should therefore:
a) Provide translations into their own language of both the current FAI Sporting Code Volume F2 applicable to F2B (that is the whole of paragraph 4.2) and of this complete Judges’ Guide.
b) Arrange suitable means and procedures to ensure that each judge is fully trained. This means arranging training courses which include regular and repeated group training in both theoretical (classroom) and practical (flight) venues where every aspect of both the current Sporting Code and of this Judges’ Guide may be examined and practised in detail.
c) Provide suitable means for officially recording each such training session attended by every judge within its national responsibility. Such official record should include dates, duration, and number of flights observed at such training sessions, and should also separately list details of all the national and international F2B contests at which each judge has been a member of the judging panel.
d) Establish selection criteria which clearly define the minimum periods of undergoing such training and of actually judging high quality F2B flights at national level before prospective judges are eligible to be nominated or invited to join judging panels at international F2B contests.
Providing all the above will ensure that the judging of all international F2B contests is carried out to the same basic standard. These measures will also enable the organisers of international contests to be sure that all judges invited or nominated to a judging panel do indeed meet the required standards of qualification and experience. The organisers of all World and Continental Championships should therefore submit a list of proposed judges’ names, together with their NAC qualification details as at paragraph c) above, to their own NAC and to the F2 Subcommittee of the CIAM.
To ensure a continuous pool of suitably qualified international F2B judges it is also recommended that, with suitable modifications, each NAC apply the criteria and procedures at the above paragraphs a) through d) inclusive to the selection and training of F2B judges for contests at national level.
Kind regards, Peter
