The International Court of Appeal has today revealed that it will uphold the exclusion of Daniel Ricciardo from the Australian Grand Prix and reject the team's appeal.
Wild speculation time - Red Bull changed the engine software after the announcement from the FIA, as announced when explaining the issues with Vettel's car. Could they have been trying to exploit the change in measurement and made a mistake, sailing too close to the wind?basti313 wrote:Sounds reasonable.

5 Hz is the cutoff frequency of the lowpass FILTER used to condition the signal from the sensors before measurement. It doesn't say anything about the measurement intervals.
Seems like it, not really sure how they thought that'd be a good idea!feni_remmen wrote:Okay, so reading the FIA report, red bull just decided during the race that the FIA sensor was wrong and then decided to do their own thing?
Could this also be why Red Bull updated the engine software prior to the Saturday free practice? Were they trying to exploit the change in measurement?gandharva wrote:If this is bulletproof, then explain why they already had to change the measurement method on friday?

In terms of signal conditioning the effect of the lowpass filter and integrator are similar but the integrator doesn't reset periodically but it just integrates last, for example, 0.2 s of the signal.basti313 wrote:Sounds reasonable.

The FIA technical representative observed thought the telemetry during the race that the fuel flow was too high and contacted the team, giving them the opportunity to follow his previous instruction, and reduce the fuel flow such that it was within the limit, as measured by the homologated sensor – and thus gave the team the opportunity to be within compliance. The team chose not to make this correction.
Yep. Seems a bit silly to me. Even if the sensor was faulty they have no recourse under those regulations. All the radio warnings and lack of authorization for the fallback method put them in a corner, even if the flow was correct metered by their model - the problem now is not the flow rate itself, but lack of adherence to FIA-mandated measurement processes amd methods. No way they will win this one, it would be open season on every measurement on the car if they got away with that.Maxion wrote:Seems like it, not really sure how they thought that'd be a good idea!feni_remmen wrote:Okay, so reading the FIA report, red bull just decided during the race that the FIA sensor was wrong and then decided to do their own thing?
Because there were rumors about the possibility of counterfeiting device measurements by pulsing the fuel flow at high frequencies.gandharva wrote: If this is bulletproof, then explain why they already had to change the measurement method on friday?
Unless Red Bull were deliberately testing the waters, they probably won't know the truth themselves. The truth lies in how you choose to determine peak consumption. I think they got disqualified for ignoring FIA directives and protocols relating to monitoring fuel flow!Paul wrote:Would be interesting to know just by how much they exceeded the limits according to FIA. Did it actually show total consumption above 100 kg? Or just peak consumption above 5.6 g per .2 seconds? Red Bull must know pretty well how much fuel the car actually had before and after the race. So to them it shouldn't be much of a question if they got it wrong (deliberately or not) or it was indeed a faulty measurement.
