Wait a minute.... the argument against aeroscreen is the top arc dimensions as if it would be a fixed value wich cannot be modified or even copied from halo?

Not really, relaxing the curvature at the top also relaxes the curvature at the bottom - which only just fits on the F1 monocoque width as it is. Obviously that could be achieved, but the monocoque would have to be wider immediately ahead of the cockpit opening.

If they would go for a “covered halo” a simple type of Lexan/polycarbonate would be enough, again, like in other prototype racing series with windscreens (like LMP1). The only thing that it would be for would be aero, a better look and small debris. But then there is still be problem of rain.

No problem, same as the reinforcements needed to support halo, when you add something to an existing structure this obviously need some redesign

Agree, I think rain and cost are the two reasons for FIA to go the halo route

Would it be too simple to suggest a flat front screen at a few inches before the cockpit edge, supports which at that distance would take up the equivalent of a pencil line, then flat panels at an angle to pass outside the cockpit and secure to the roll bar?

Flat panels of something like lexan would be (relitivly) low cost to replace, so could be per race if needed, and at a reasonable thickness would be strong enough to support its self and the inverted car as long as it was framed to prevent snapping.

When I started motorcycling everyone wore airmans goggles which had 2 flat panes with an angle (each eye) and in seconds your brain adjusted to ignore the line in much the way you ignore your nose when looking down

The curve isn't the issue, the support also not really. In practice you just glue a curved plane of polycarbonate to the Halo. Because of the bigger distance then for instance your glasses or visor, rain and dirt on the screen is a problem. dirt can be handled with tear offs during pit stops but rain, is, as anybody who tries to see trough their motorbike windscreen during a bit of rain knows, a big no no.

by the way, old style motor goggles have their "fold" at the sides, not down the middle

Which is about where the 'pillars' would appear with a flat front screen. About 45deg either side of centre line.

but what is wrong with the central pillar? the 45 degree angles are right in line with the apex line, so one eye is obstructed by your nose and the other one with that pillar..

You then still have to join the flat front screen (flat horizontally, not vertically) to the side screens so some bracing would be needed there anyway. No need to add a central bar.

In the rain it will be a problem as mentioned above as more light come from above than through the windshield (as quiet a bit gets reflected by the water droplets). Only way to avoid this is to cover the top.
