CHAPTER 12 RACE Appendix 6- Competition Regulations
This Appendix must be read in conjunction with the relevant provisions of Chapter 5 Officials.
1. Handicapping
1.1. Any handicap will be based on the Handicapper’ s estimate of the potential performance of the Vehicles entered. Speeds achieved during Practice will be used as a guide – unless some other basis is advised in Official Documents.
1.2. A handicap may be modified after initial publication but a finalised list of handicaps should be published at least 30 minutes prior to the start of a Race.
1.3. In the case of races in which the handicap is wholly or partly based on Practice times a Driver who in any lap improves their best Practice lap time by more than 5 % may be disqualified by the Clerk of the Course. This penalty may be waived if the Handicapper advises the Clerk of the Course of any extenuating circumstances.
1.4. For handicap races the handicap shall be so arranged by the allocation of credit laps that all Vehicles will have left the starting area before the limit Vehicle has completed its first lap. Vehicles due to start at different times should not be placed in the same row on the starting grid.
2. Timing
2.1. The completion of the first and subsequent laps shall be timed when each Vehicle crosses the control line unless the Official Documents state otherwise.
2.2. At all times throughout the Event competing Vehicles shall be fitted with a working timing identification module( i. e transponder). This must be compliant with the Timekeeper’ s equipment. The module identification number should be submitted to the Event Secretary on the Entry form. It is the responsibility of the Competitor to ensure that the module is working and safely fitted in a suitable position on the Vehicle. Failure of the module may result in the competing Vehicle being untimed.
2.3. Where for whatever reason timing is carried out manually the timing of a Vehicle crossing a control line shall be taken at the moment when the centre of the leading wheel( s) pass( es) over that line.
2.4. Transponder only timing must not be to an accuracy of less than 0.01 seconds.
2.5. Transponders must be from the ASN approved list and used in conjunction with decoders certified in accordance with Ch. 5 App. 18 Chart. 6.
2.6. The fitment of the transponder must be in accordance with the manufacturer’ s instructions at a predetermined position on the Vehicle as detailed in the Official Documents.
3. Practice
3.1. Every Driver including Drivers of Vehicles which are to give performance demonstrations must be given the opportunity of practicing in conditions similar to those to be expected in the Competition and any Driver who has not previously raced over the course in its current configuration within the preceding 2 Competition calendar years must complete at least three Practice laps in the Vehicle to be raced by the Driver during which the Driver shall satisfy the Clerk of the Course as to their competence. Drivers must be given at least the following opportunity for Practicing:
3.2. Organisers will provide a period sufficient to allow at least three laps of Practice in the prevailing conditions.
3.3. It is recommended to schedule a period of 10 minutes of Practice if the Track is less than one mile in length or 15 minutes for a track between 1 mile and 2.5 miles and 20 minutes for tracks over 2.5 miles.
3.4. Organisers will provide a separate Practice session for each Race, Championship or Series( unless the Official Documents state differently). Vehicles practicing entirely out of session will be placed at the back
