Silverstone is hopeful it will be able to welcome 140,000 fans to the British Grand Prix in July.
The July 18 event is set to take place four weeks after the proposed dates the UK government will end Covid-19 restrictions in England.
To fill gaps in the schedule caused by the pandemic, Silverstone hosted two races in 2020 - the British Grand Prix and the 70th Anniversary Grand Prix - but both took place behind closed doors. This year it will go back to hosting one race as normal.
Circuit boss Stuart Pringle remains cautious about the possibility of a full house but said the venue benefits from the fact it can spread fans out over a large area.
