"McLaren's controversial back wing design has been agreed by FIA."
The F1 Governing body decided to look at the wing after Red Bull's Christian Horner admitted it had been causing :a bit of excitement in the paddock. The FIA's Charlie Whiting had planned to check the design at McLaren's Working head office last week, but after air travel delays from Brazil opted instead to leave the inspection until the day of scrutinizing for the season opener.
And it is supposed McLaren's system involves an air inlet on the upper left monocoque top, which is opened and closed by a cause activated by the drivers' knee. Germany's Auto Motor und Sport quoted an FIA official as telling it as a "simple but brilliant trick".
