Formula 1 is in the midst of its summer testing ban, but the Renault, McLaren and Force India teams have nonetheless turned out for development action on a British airport.

Even during the August break, teams are still allowed to conduct short shakedowns and aerodynamic tests not exceeding 50kms.

According to the local Wilts and Gloucestershire Standard newspaper, Renault - believed to be working on a new braking system - has been in action at Kemble Airport, which is located about an hour's drive from the French team's Enstone (UK) base.

Two of the team's F1 cars were in action on the runway, but the identity of the drivers is not known.

McLaren and Force India also tested at Kemble last week, sparking six complaints about the noise from local residents.

"I have written to the airfield letting them know how many complaints we got this week and last week," said environmental health officer Ray Brassington.
