Article C3.10.2
Front Wing Endplate Body
Chapter: C3
In Simple Terms
The front wing endplate (the vertical piece at the wing's edge) must fit within a defined space and can have up to two distinct sections when viewed from the side. The curved surfaces must have smooth radiuses - outer curves can't be tighter than 5mm, and inner curves can't be tighter than 100mm - to prevent sharp edges that could be unsafe or provide unfair aerodynamic advantages.
- Endplate bodywork must stay completely within the regulated RV-FWEP-BODY boundary zone
- Maximum of two separate sections allowed in any Y-Plane (vertical cross-section)
- Convex curves (bulging outward) must have a minimum 5mm radius to avoid sharp edges
- Concave curves (indented inward) must have a minimum 100mm radius for aerodynamic fairness
Official FIA Text
Front Wing Endplate Body Bodywork must lie in its entirety within RV-FWEP-BODY and have up to two sections in any Y-Plane. Aerodynamic Surfaces must contain no convex radius of curvature less than 5mm and no concave radius less than 100mm.
