Mercedes driver Lewis Hamilton believes Formula 1 needs to find a solution in order to prevent a repeat of Friday’s aborted sessions at the Chinese Grand Prix.
The first session, which took place in drizzly conditions, was truncated due to the medical helicopter being unable to land at the designated hospital, 38km from the track, because of low-lying cloud.
The second 90-minute session did not start, because of the restrictions on the medical helicopter, and the decision was eventually made to abort running.
Hamilton used part of the stoppage to walk over to the grandstand on the pit straight and signed caps, which were distributed to some attending fans.
It was the first time an entire session was cancelled since the corresponding practice at Austin two years ago, and Hamilton believes changes need to be made.
“The track was absolutely fine and we could have run all day today with no issue if it weren't for the clouds,” said Hamilton.
“It's not good for the fans watching on TV and even worse for all those people in the stands, who have paid money to come out here from the city or even from other countries.
“They've barely seen a car on track today, which must be tough for them.
“We need to work together with the FIA and FOM to find a solution or an alternative plan of some kind when we have circumstances like this in the future.”
Brighter weather is forecast for Saturday, though gloomier conditions are anticipated for Sunday.
