After last week controversy over the legality of McLaren's rear wing design, FIA officials in Bahrain declared that the design is legal and even more brilliant in its design concept.
The FIA agreed to look at the wing after Red Bull and Ferrari question its validity arising a similar to 2009 double-diffuser issue. FIA's Charlie Whiting had intended to check the design at McLaren's Woking headquarters last week, but after flight delays from Brazil opted instead to leave the inspection until the day of scrutineering for the season opener. As it wasn't certain whether the design could pass FIA's examination, McLaren team had prepared a "Plan B" conventional design to implement in the car even by the last minute before the Grand Prix.
It is believed McLaren's system involves an air inlet on the upper left monocoque top, which is opened and closed by a trigger activated by the drivers' knee.
