A Technical Directive has been issued to give guidance to the teams about the measures the FIA intends to take to tackle the problem. These include:
1. Closer scrutiny of the planks and skids, both in terms of their design and the observed wear
2. The definition of a metric, based on the car’s vertical acceleration, that will give a quantitative limit for acceptable level of vertical oscillations. The exact mathematical formula for this metric is still being analysed by the FIA, and the Formula 1 teams have been invited to contribute to this process.
In addition to these short-term measures, the FIA will convene a technical meeting with the Teams in order to define measures that will reduce the propensity of cars to exhibit such phenomena in the medium term.
