Formula 1 governing body, the FIA have clarifies the controversial radio messages rules in the wake of championship leader Nico Rosberg’s penalty at the British grand Prix.
Rosberg was hit with a 10-second time penalty that cost him second place in the race following Mercedes were deemed to have breached the regulations governing banned radio communication.
In a technical directive issued to F1 teams on Wednesday, the FIA has now significantly changed item number two on the list of permitted messages.
It previously read: “Indication of a critical problem with the car. Any message of this sort may only be used if failure of a component or system is imminent and potentially terminal.”
It now reads: “Indication of a problem with the car. Any message of this sort must include an irreversible instruction to enter the pits to rectify the problem or to retire the car.”
TD/038-16 clarifies the restrictions apply “at all times the car is out of the pit lane with the engine running and the driver on board”, allowing teams to pass further messages to the driver during pit stops.
Teams are also permitted to give drivers “information concerning damage to the bodywork of the car” as well as “instructions to select driver defaults, this must be for the sole purpose of mitigating loss of function of a sensor, actuator or controller whose degradation or failure was not detected and handled by the on-board software.”
The FIA adds: “It will be the responsibility of any team giving any such instruction to satisfy the FIA technical delegate that this was the case and that any new setting chosen in this way did not enhance the performance of the car beyond that prior to the loss of function (see Article 8.2.4 of the Technical Regulations).”
