Revised front-wing flex test 29 August 2010

The front wing must be no lower than 75mm above the reference plane, which is the lowest point of the car without the plank (yellow dotted line). To check compliance with this rule, prior to this weekend's Belgian Grand Prix, in scrutineering a load of 50kg was applied to the endplates (smaller red arrow), with a permitted flex of up to 10mm. After rival teams voiced suspicions that the front wings of Red Bull and Ferrari were flexing more than this at speed, the FIA has doubled the load applied in the test to 100kg, now measured in the middle of the wing's side section (larger red arrow), with a permitted flex of 20mm. Both Red Bull and Ferrari cleared scrutineering at Spa.
