After losing the first day of practice at Motegi to the weather, Race Direction has announced contingency plans for a schedule to allow practice, qualifying and the races to be run at the Japanese circuit however the weather turns out.

With rain set to continue on Saturday morning, but clear up on Saturday afternoon and Sunday, schedules have been drawn up to take account of all the possible combinations of weather.

The problem is not the rain, it is the fog and low-hanging clouds, Race Director Mike Webb explained in a press conference at Motegi. Because of the location of the Twin Ring circuit, set in a bowl up in the hills in the Tochigi district in Japan, the combination of heavy clould and relatively weak winds saw the surrounding hills cloaked in cloud.

That cloud, and the reduced visibility it caused, meant that the medical helicopter, which is required to transport injured riders to the nearest hospital, was not allowed to fly, Japanese aviation law preventing helicopters flying in such circumstances. The helicopter had not yet arrived at the circuit, being stationed a few minutes flight time away.

Without the medical helicopter, practice could not be run safely, as the hospital designated by the chief doctor at the circuit is an hour away by road. Should a rider sustain a severe or life-threatening injury, they could not be transported to the hospital quickly enough to ensure proper care, Webb explained.

The lack of visibility was why Friday practice had been postponed all day, rather than canceled right away. Practice could not go ahead without the helicopter on site, but it was waiting on standby for permission from the Japanese aviation authority, ready to fly to the circuit as soon as they were given clearance. The cloud never lifted enough for the helicopter to be allowed to fly, however, and in the end, practice had to be called off.
