The big question is how does it pass the deflection test? This is actually rather straight forward. In this case, the load test is carried out with the endplates disconnected from the bodywork and thus the wing assembly is allowed to rotate to its stop (2) before the load test apparatus is attached. So only normal deflection will ever be seen. One has to wonder what the scrutineers make of all that as clearly the way the wing assembly is tested isn't the way the car runs on the track... Turns out the regulations actually mandate that the wing assembly is tested with the endplates detached (Art 3.6.2 c/). The point being that the FIA doesn't want the car designers to rely at all on the endplates handling the rear wing loads in case of an accident. So sound thinking in that regards. However, the car would still be presented at scrutineering with a wing that was clearly out of its operating angle of attack given the extreme nose up.
