We've divided the options available for Saturday and Sunday into 'Plan A', 'Plan B' and 'Plan C'...
Plan A:
“If we are able to run tomorrow [Saturday] morning, we will run free practice for as long as possible and then move on to a normal Saturday afternoon qualifying schedule and a normal Sunday schedule,” said Webb.
Plan B:
“If we are not able to run tomorrow morning, Saturday afternoon will be deemed free practice and will be run as long as possible. Then a heavily revised schedule for Sunday - involving practice, qualifying and the race - will be run.
Plan C:
“If it is not possible to practice at all tomorrow, we are still expecting Sunday's weather to be significantly better and we have a provisional, heavily revised schedule, that includes practice, qualifying and the race on Sunday. We are committed to running the Japanese Grand Prix and are doing everything we can to make it happen.”
