Max legal height of an aero screen ?

[Rocket.]

Does anyone know the max legal height of an aeroscreen i.e. point after which it would be deemed a windscreen and need wipers etc. ?

I have read 20cm but not sure if there is a specific measurement but imagine there would be for the IVA.

Thanks

It's measured relative to the seating position (and varies according to how steeply reclined the seat is).

See page 220 of the IVA manual on this link

The way it is measured at IVA is Heath Robinson at his finest.

There is a hugely complicated description in the IVA manual but, as a rule of thumb, you should be able to just see the very front of the car over the screen when you are seated in your normal driving position.

Fit the aero screen after IVA, I believe you can IVA without a screen

Thanks all.
