The FIA have concluded their investigation of the accident involving Marussia driver, Jules Bianchi, at this year’s Japanese Grand Prix. The results concluded that the French driver did not slow significantly enough in double-yellow conditions.
The wording, specifically, was:
“Bianchi did not slow sufficiently to avoid losing control at the same point on the track as Sutil. If drivers adhere to the requirements of double yellow flags, as set out in Appendix H, Art. 22.214.171.124.b, then neither competitors nor officials should be put in immediate or physical danger.”
The FIA agreed that water drainage from the circuit and other cactors played intot he situation—including the effectiveness of the wet-weather tires—but it also concluded that there may have been a FailSafe system that did not work properly due to the configuration of the Marussia car. The statement read:
“During the 2 seconds Bianchi’s car was leaving the track and traversing the run-off area, he applied both throttle and brake together, using both feet. The FailSafe algorithm is designed to over-ride the throttle and cut the engine, but was inhibited by the Torque Coordinator, which controls the rear Brake-by-Wire system. Bianchi’s Marussia has a unique design of BBW, which proved to be incompatible with the FailSafe settings. The fact that the FailSafe did not disqualify the engine torque requested by the driver may have affected the impact velocity; it has not been possible to reliably quantify this.”
Much of the debate has centered on the fact that a safety car had not been deployed but the accident panel felt there was nothing out of the ordinary about how the race was ran and the conditions in which it continued to race.
Several criticisms have been made about the lack of a safety car or red flag being called for the race and why the FIA would allow a tractor on the outside run-off area of a corner while the track was still “hot”. The FIA pointed out that it has happened this way for 384 other incidents over eight years.
Twitter and Facebook have been ripe with vitriol and harsh words for the FIA ranging from outrage to accusations of self-preservation and that’s not helping the matter. Some have questioned the integrity of the FIA and Accident Panel members but I can assure you that the panel members are not FIA shills. These are veteran F1 agents such as Brawn, Domenicali, Fittipaldi and Wurz.
What is intriguing are the recommendations and one of these includes a time limit for starting a race owing a nod to the criticism of low-light situation such as the Japanese Grand Prix adding to the difficulty. The late starts have been pushed over the last few seasons to accommodate the UK prime-time audience but many circuits lack lighting and this leaves a twilight situation for the drivers.
One item that was approved for 2015 is the Virtual Safety Car which was tested at the final few races of 2014. The FIA have deemed it a workable solution and have determined it will be launched in the 2015 season in order to properly slow cars down in yellow-flag zones.
The Report Summary
On lap 43 of the Japanese GP, Jules Bianchi lost control of his Marussia in Turn 7, and struck a mobile crane that was recovering Adrian Sutil’s Sauber, which had crashed the lap before. Bianchi suffered life-threatening injuries to his head, and was evacuated to hospital by ambulance.
The weather conditions at the time were rain and a deteriorating track condition, and the section of the track where the accident occurred was subject to double yellow flags, due to Sutil’s crash.
A review of all the evidence and other information about the events leading up to Bianchi’s accident has been carried out by the 10-man Accident Panel, appointed by the FIA. The Panel has issued a 396-page report on their findings with recommendations for improvements, many relevant to all of motorsport. This has been presented to the FIA World Motorsport Council.
The review of the events leading up to Bianchi’s accident indicate that a number of key issues occurred, which may have contributed to the accident, though none alone caused it:
1. The semi-dry racing line at T 7 was abruptly narrowed by water draining onto the track and flowing downhill along it. Both Sutil, and Bianchi one lap later, lost control at this point in T 7.
2. Sutil’s car was in the process of being recovered by mobile crane when Bianchi approached Sectors 7 and 8, which include the part of T 7 where the recovery was taking place. Sectors 7 and 8 were subject to double yellow flags.
3. Bianchi did not slow sufficiently to avoid losing control at the same point on the track as Sutil.
4. If drivers adhere to the requirements of double yellow flags, as set out in Appendix H, Art. 126.96.36.199.b, then neither competitors nor officials should be put in immediate or physical danger.
5. The actions taken following Sutil’s accident were consistent with the regulations, and their interpretation following 384 incidents in the preceding 8 years. Without the benefit of hindsight, there is no apparent reason why the Safety Car should have been deployed either before or after Sutil’s accident.
6. Bianchi over-controlled the oversteering car, such that he left the track earlier than Sutil, and headed towards a point “up-stream” along the barrier. Unfortunately, the mobile crane was in front of this part of the barrier, and he struck and under-ran the rear of it at high speed.
7. During the 2 seconds Bianchi’s car was leaving the track and traversing the run-off area, he applied both throttle and brake together, using both feet. The FailSafe algorithm is designed to over-ride the throttle and cut the engine, but was inhibited by the Torque Coordinator, which controls the rear Brake-by-Wire system. Bianchi’s Marussia has a unique design of BBW, which proved to be incompatible with the FailSafe settings.
8. The fact that the FailSafe did not disqualify the engine torque requested by the driver may have affected the impact velocity; it has not been possible to reliably quantify this. However, it may be that Bianchi was distracted by what was happening and the fact that his front wheels had locked, and been unable to steer the car such that it missed the crane.
9. Bianchi’s helmet struck the sloping underside of the crane. The magnitude of the blow and the glancing nature of it caused massive head deceleration and angular acceleration, leading to his severe injuries.
10. All rescue and medical procedures were followed, and their expediency are considered to have contributed significantly to the saving of Bianchi’s life.
11. It is not feasible to mitigate the injuries Bianchi suffered by either enclosing the driver’s cockpit, or fitting skirts to the crane. Neither approach is practical due to the very large forces involved in the accident between a 700kg car striking a 6500kg crane at a speed of 126kph. There is simply insufficient impact structure on a F1 car to absorb the energy of such an impact without either destroying the driver’s survival cell, or generating non-survivable decelerations.
It is considered fundamentally wrong to try and make an impact between a racing car and a large and heavy vehicle survivable. It is imperative to prevent a car ever hitting the crane and/or the marshals working near it.
A number of recommendations for improvements have been proposed, relevant in many cases to all of motorsport. They include the following:
1. A new regulation for double yellow flags:
Proposed new Appendix H Article (possibly under 188.8.131.52 b):
The Clerk of the Course will impose a speed limit in any section of track where double yellow flags are being displayed.
It is proposed that a Working Group, made up of FIA Race Directors and Stewards should meet and draw up detailed regulations and guidelines for the application of this new regulation, in time to apply it in 2015 across international circuit racing.
2. Safety critical software:
A review of safety critical software and measures to check its integrity will take place.
3. Track drainage:
Guidelines on circuit drainage will be reviewed, to include drainage off access roads.
4. 4-hour Rule:
Article 5.3 of the F1 Sporting Regulations states that:
However, should the race be suspended (see Article 41) the length of the suspension will be added to this period up to a maximum total race time of four hours.
It is proposed that a regulation or guideline be established such that the Start time of an event shall not be less than 4 hours before either sunset or dusk, except in the case of night races.
It is also recommended that the F1 Calendar is reviewed in order to avoid, where possible, races taking place during local rainy seasons.
5. Super Licence
It is proposed that drivers acquiring a Super Licence for the first time should undertake a course to familiarise themselves with the procedures used by F1 in running and ensuring the safety of an event.
It is also proposed that new licence holders pass a test to ensure that they are familiar with all the relevant regulations.
6. F1 risk review
Consideration will be given to a review of F1 risk, in order to ascertain whether there are any significant holes in the safety defences, such that an unforeseen combination of circumstances could result in a serious accident.
It is part of the challenge of a racing driver to drive his car as fast as possible given the track conditions combined with the characteristics of his tyres. Although the characteristics of the wet weather tyres provided by Pirelli did not influence Bianchi’s accident or its outcome in any significant way, it is recommended that provision is made for the tyre supplier to develop and adequately test wet weather tyres between each F1 season, such that it is able to supply the latest developments to the first event.
