More About Safaris/Safari Lites 2017

All the Information applies to Safari and Safari Lites under review 04/02/2017

In order to avoid vehicles and drivers of widely differing speed capabilities being randomly mixed on the start line, the AWDC has a seeding system to select those groups who are significantly faster than the average entrant. Competitors are seeded according to performance and can be upgraded or downgraded as necessary. Officials will compare individual run times of competitors when a request is made for a change of seeding.

Vehicles are distinguished by the following colour code:

RED   very fast vehicles

BLUE   the next fastest

YELLOW  above average speed

GREEN  standard seeding

Each vehicle shall carry a forward facing coloured seeding sticker. These are available on registration and at Safari Control. They must be on the vehicle before scrutineering. Any vehicle not so identified will be deemed to be GREEN. Scrutineers will issue temporary markers when required. Entrants are advised to fix their own markers after seeding has been advised.

Safari Register

The Safari Register is the annual list of Competitive Safari entrants maintained by the AWDC. Participants retain a single competition number for a year.

Anyone wishing to enter a safari must join the Safari Register in advance – contact the Safari Coordinator for more details. The competition number issued is valid for all safaris from January 31st until the following Annual General Meeting. Applications to join the Register may be made at any time. Renewal forms for registered drivers are avaible on line and must be completed for the  championship safari/Safari Lite of the season.

Up to three drivers may register to drive a single vehicle. Changes of drivers' details and vehicle details are permitted providing one of the drivers remains registered for the year under a single competition number. Advice on all changes must be made in writing to the AWDC. Failure to do so will result in forfeiture of any points gained whilst Register details were incorrect.

Championship points are added to the Register at the end of each Safari. At the end of the season the Championship placings determine the Competition Number allocation for the following season.

Safari Results

Results from each event will be sent as soon as practical by email to all competitors who have requested them. In addition results will be posted on the club’s website and in the magazine when space permits.

Safari Timing

The method used is to record the actual time of day to the second i.e. 10:15:20, that a vehicle starts and the same at the finish. The start time is then subtracted from the finish time to give the ELAPSED TIME.

Each vehicle starts a run at an allocated start interval set by the Timekeepers. A series of Red, Amber and Green traffic lights control the start. When the Green light is illuminated the timing for that run begins.

Each vehicle breaks an infra red beam at the Finish to automatically register its arrival time. In safari control is the start terminal linked to the main computer which operates the Start Lights and also records the start times of each competitor. The traffic lights automatically switch back to red after each vehicle crosses the line. As each vehicle starts, its number, run number and start time is printed by the Start Log Printer and this information is stored in the Results Computer.

The timing signal received at safari control from the Finish Line Sensor is fed to the finish terminal which records and prints out all finish times and vehicle numbers as well as sending the information to the Results Computer.

After crossing the finish line, vehicles must wait at the STOP sign adjacent to Safari Control until the timekeeper acknowledges that the correct finish time had been allocated to the correct vehicle.

The times at the start and finish are recorded on the competitor’s individual timecards. The Chief Timekeeper then checks these cards against the all electronic replicas held in the Results Computer. The Results Computer calculates the ELAPSED TIME.

At the end of the competition, the Timekeepers re-check the times of each competitors runs, adds maximums for incomplete runs, checks to find those competitors with too many maximums and moves them to a list of non-finishers, sorts the overall results, calculates the championship points to be awarded and adds them to the annual championship table, then finally sorts the updated championship results and produces a full set of printouts.

The Overall Results printout includes the individual time penalties for each run plus class positions and so enables competitors to compare each others results after the meeting.

How Penalties are awarded

The PENALTIES awarded on each run are derived by subtracting the Penalty Free Time Allowance, known as the PFTA, from the ELAPSED TIME. The penalties cannot be less than zero or greater than the MAXIMUM PENALTY.

The length of the course is the main factor governing the PFTA. The PFTA is normally calculated on the basis of the time taken to drive the course at 35mph, although on exceptionally difficult terrain it may be reduced to 30mph or on very fast courses it may be increased to the 40mph maximum average speed the MSA will allow in Competitive Safaris. The PFTA is rounded up to the nearest minute and is calculated as follows:

PFTA (in minutes) = Course mileage/mph x 60 minutes
(rounded up to the nearest minute)

e.g. a 5 mile course at 40mph = 5 /40 x 60 = 7.30 which is then rounded up to 8 minutes.

The TIME ALLOWED is calculated from the PFTA and this is equal to four times the PFTA. This results in the minimum average speed that must be maintained in order to avoid receiving a maximum penalty of between 7 and 10mph e.g.

MAXIMUM PENALTY = 3 x PFTA
TIME ALLOWED/RUN = 4 x PFTA

In order to calculate the time allowed for each competitor to complete the event other factors have to be considered. They are:

Start Interval: The time interval between vehicles leaving the start line.

Run Interval: The time between the last vehicle starting a run and the first vehicle starting the next run. This is dependant upon the length and type of course, but obviously more time has to be allowed on a long course than on a short one. For example 90 seconds per mile of course is allowed and on a 5 mile course this works out at 7½ minutes.

Time, Run to Run: To calculate this time, the number of starters has to be known so that these can be multiplied by the 30 second start intervals to give the time taken to start all the vehicles. This time is then added to the RUN INTERVAL to give a possible TIME, RUN TO RUN.

To create a SAFARI TIMETABLE from all the variable factors requires a fair amount of work and so our computer carries out this task before the start of the event. From the timetable the organisers select the number of runs to be attempted, looking particularly at the calculated start times of the first and last vehicle on each run and the total course mileage. Having reached a decision, the data in the table is displayed for the reference of the competitors. However the event timetable is subject to change by the Clerk of the Course, once the event has started.

Any competitor not ready to start their first run by the time all the other competitors have started run one forfeit their total time allowance.
