- RBR lawyers ask LOM, why the sensors showed a change from 1.3 to 1.8% in lap 37. Lom says, it was a minor change that went back on the next lap. There was no ramping up, as RBR states.
- Lom shows a chart with all of RIC laps, his corresponding fuel flow and lap times. Aside from laps 13 to 17 it shows measurings all the time over 100kg/h. First 12 laps between 100.5 and 100.8, after the SC phase between 100.4 and 101.1 kg/h. The last four laps, when RIC fought against MAG, read 101, 101, 101 and 101.1
- more numbers. Lom shows the discrepancy between RBR model and FIA measuring. Without the FIA offset the fuel flow would have been between 99.02 and 103.37 kg/h
- RBR lawyers go at him, want to know what position he has within FIA. Want to know why the FIA choose the Gill ffs. Lom says there have been two candidates, the other one presented a too complicated solution, which reacted too much to vibrations. Says Gill were the only ones able to produce a ultrasonic sensor working reliably in a racing environment.
- they ask him why the FIA put a backup model into the rules. Lom says its usual for the FIA to do this for crucial data. Says the backup model is no measuring, but a mathematical model, which the FIA only allows teams to use when its certain the ffs failed. RBR lawyers say that technical directive 0.3.1.30 says the sensors to be the primary system, so the backup had to be sensors as well and no math model (I don´t get it, doesn´t that contradict the teams stance to use their own math model??)
- Lom has now to explain, how the backup math model works. It was at first planned, to have every team make their own model, and put this through a lengthy validation process. FIA then decided to easen the process, sending a software expert to every team controlling each teams software, comparing it with engine tests.
