It has become apparent that the FIA will paint markings on the track surface to ensure fans and commentators know when and where the adjustable rear-wing can be activated.
The new overtaking aid has come in for much criticism, with the worry that fans won’t understand when it’s in use – to address this matter, two white lines will be painted on the corner leading onto the main straight to indicate when two drivers are within a second of one another.
Another white line will be painted further down the main straight to indicate when the wing can be lowered into the drag-reducing position.
This line will begin 600 metres before the next corner, in which the flap will return to the default position upon application of the brakes.
The magic number of ‘600 metres’ was chosen by the FIA after much research, to ensure overtaking wouldn’t become too easy, but was possible.
The usable zone in Bahrain will be along the start/finish straight, this is the same for Australia and Malaysia.
