In the MD11, I think this lack of rudder authority has caused issues because, as you know, when you kick the rudder and add a horizontal component of lift, you lose vertical component of lift as the plane only generates so much lift. I think this might play into what causes the plane to land very hard on one side, crushing one main gear and causing a roll over.
Is this correct? I understood the MD11 had an abundance of rudder and this was even emphasised during upset recovery training.
