Parc Ferme

Published with permission from the Federation Internationale de l' Automobile.

34) POST QUALIFYING PARC FERME
34.1 Each car will be deemed to be in parc ferme from the time at which it leaves the pit lane for the first time during qualifying practice until the green lights are illuminated at the start of the formation lap which immediately precedes the start of the race.
Between these times, other than when cars are returned to the parc ferme overnight, the following work may be carried out :
- engines may be started ;
- subject to the requirements of Article 29.1 fuel may be added or removed and a fuel breather fitted ;
- wheels and tyres may be removed, changed or rebalanced and tyre pressures checked ;
- spark plugs may be removed in order to carry out an internal engine inspection and cylinder compression checks ;
- heating or cooling devices may be fitted ;
- a jump battery may be connected and on board electrical units may be freely accessed via a physical connection to the car ;
- the main electrical battery and radio batteries may be changed ;
- the brake system may be bled ;
- engine oil may be drained ;
- compressed gases may be drained or added ;
- fluids used for replenishment must conform to the same specification as the original fluid. Fluids with a specific gravity less than 1.1 may be drained and / or replenished, however, no replenishment may take place less than one hour and 30 minutes before the start of the formation lap unless specific approval has been given by the FIA. In order to ensure that fluids are not being used as ballast the FIA reserves the right to weigh cars which took part in Q3 at random during the one hour period commencing one hour and 30 minutes before the start of the formation lap. When a car is weighed in this way, and taking into account any fuel added under Article 29.1b), its weight must be within 3kg of
its weight at the completion of its final qualifying run, if not, fluids other than fuel may be replenished or drained under FIA supervision ;
- the aerodynamic set up of the front wing may be adjusted using the existing parts. No parts may be added, removed or replaced ;
- if the FIA technical delegate is satisfied that changes in climatic conditions necessitate alterations to the specification of a car, changes may be made to the air ducts around the front and rear brakes and radiator ducts. These changes may be made at any time after the message “CHANGE IN CLIMATIC CONDITIONS” is shown on the timing monitors, from this point the choice of brake cooling and radiator ducts is free.
- bodywork (excluding radiators) may be removed and / or cleaned ;
- cosmetic changes may be made to the bodywork and tape may be added ;
- any part of the car may be cleaned ;
- on board cameras, timing transponders and any associated equipment may be removed, refitted or
checked ;
- any work required by the FIA technical delegate ;
- changes to improve the driver's comfort. In this context anything other than addition or removal of padding (or similar material) and adjustment of mirrors, seat belts and pedals may only be carried out with the specific permission of the FIA technical delegate ;
- repair of genuine accident damage ;
- any parts which are removed from the car in order to carry out any work specifically permitted above, or any parts removed to carry out essential safety checks, must remain close to it and, at all times, be visible to the scrutineer assigned to the relevant car.
Any work not listed above may only be undertaken with the approval of the FIA technical delegate following a written request from the team concerned. It must be clear that any replacement part a team wishes to fit is similar in mass, inertia and function to the original. Any parts removed will be retained by the FIA. However, if a team wishes to change a part during the qualifying session and/or on the grid before the start of the race, this may be done without first seeking the permission of the technical delegate, provided it is reasonable for the relevant team to believe permission would be given if there was time to ask and the broken or damaged part remains in full view of the scrutineer assigned to the car at all times.
34.2 At the end of the qualifying practice at least six cars will be chosen at random to undergo further checks, once informed their car has been selected the team concerned must take the car to the parc ferme immediately.
34.3 At some time before 18.30 all cars used during the qualifying practice session (or which were intended for use but failed to leave the pit lane) must be taken to the parc fermé, where they will remain secure until the following day. For marketing purposes this deadline may be extended for one car from each competitor for a maximum of two hours by prior arrangement with the FIA technical delegate. However, no work of any kind may be carried out on the car after 18.30.
Whilst cars are in the parc fermé they may be covered and fitted with devices to keep them warm, no team personnel will be permitted there unless specifically authorised by the FIA technical delegate.
34.4 At 08.30 on the day of the race, or at other times if the relevant Event timetable makes this necessary, teams will be permitted to take their cars back to their garages where, again, they will remain under parc fermé conditions until the start of the race.
34.5 If a competitor modifies any part on the car or makes changes to the set up of the suspension whilst the car is being held under parc ferme conditions the relevant driver must start the race from the pit lane and follow the procedures laid out in Article 38.3.
34.6 One scrutineer will be allocated to each car for the purpose of ensuring that no unauthorised work is carried out whilst cars are being held under parc ferme conditions.
34.7 A list of parts replaced with the specific agreement of the FIA technical delegate whilst cars are being held under parc ferme conditions will be published and distributed to all teams prior to the race.
34.8 In order that the scrutineers may be completely satisfied that no alterations have been made to the suspension systems or aerodynamic configuration of the car (with the exception of the front wing) whilst in post-qualifying parc ferme, it must be clear from physical inspection that changes cannot be made without the use of tools.

44) POST RACE PARC FERME
44.1Only those officials charged with supervision may enter the post race parc ferme. No intervention of any kind is allowed there unless authorised by such officials.
44.2 When the parc ferme is in use, parc ferme regulations will apply in the area between the Line and the parc ferme entrance.
44.3 The parc ferme shall be secured such that no unauthorised persons can gain access to it.
