Helmut Marko has said around 39,000 fans could fill the grandstands for the two F1 races set to be held in Austria this year.
Formula 1 has welcomed some fans back so far this year in a limited capacity, with crowds returning in some form at the races in Spain and Portugal.
Last year the Red Bull Ring hosted the sport's first ever double header for the season opener, but those races ran behind closed doors due to the pandemic.
However, Red Bull team advisor Marko is confident that fans will be back for the upcoming races in his home country next month, he told Formel1.de.
"The grandstands are equipped with their own entrances and exits. This means that each stand is a unit of its own and nobody comes into contact with each other," he said.
This means that, under current Austrian guidelines limited spectators to 3000 per venue, the 13 grandstands could theoretically host up to 39,000 spectators.
Marko added that the Red Bull team had shown it was capable of running secure events for the public after its experience over the last year.
"Red Bull has already shown what a super organization it is and that we can organize in a very efficient way, with test certificates, investigate whether whatever is prescribed by the authorities or the government,” he said.
"I therefore assume that we will have an acceptable number of spectators."
