Subsequent further conference in Spain, F1's teams has made the unanimous conclusion to ban the f-duct device from the 2011 season onwards. The fundamental feature, first initiate by McLaren, allows drivers to stall air to their car's back wing and so allocate better straight-line speeds.The Formula One Teams Association (FOTA) having gathered in the Circuit de Catalunya paddock, it is assumed that McLaren was against banning the f-duct - since introduced by Sauber, Williams and Ferrari as well - although teams did finally reach the decision universally courtesy of a voting process.
Utilizing an air escape which is located on the top of the car's monocoque, drivers are able to cover a hole “with their knee, in McLaren's case or with the back of their hand, in Ferrari's case” in order to reduce the amount of air which travels to the rear wing, meaning that there is less down-force and therefore higher top speeds on straights. As there is no moving mechanical part necessary, the device is legal under the current FIA technical policy but will disappear once the current campaign comes to an last part.
