So, if it's a flat wing, how does the angle of attack or the camber of the wing profiles varies with this point? Can the flap have a bigger angle of attack as usual?
A similar wording was brought in for the front wing in 2019 so that's a good place to show how it works.
It relates to the green line below, so across the span. At the tip where the wing profiles sweep to the "cone" section the wing "subtends" at an angle of around 35-40° then where it joins the footplate it has an angle over 90° (negative from the zero axis) as you follow the line around.
To ban these tip cones the FIA said the maximum angle the wind could subtend was 15°, outboard of Y450, so wings now look like this. i.e. quite flat by comparison.
