Canted vertical stabilizers are another distinguishing design element, one among several other such elements that enable the Hornet's excellent high angle of attack ability, including oversized horizontal stabilators, oversized trailing-edge flaps that operate as flaperons, large full-length leading-edge slats, and flight control computer programming that multiplies the movement of each control surface at low speeds and moves the vertical rudders inboard instead of simply left and right. The Hornet's normally high angle of attack performance envelope was put to rigorous testing and enhanced in the NASA F-18 High Alpha Research Vehicle (HARV). NASA used the F-18 HARV to demonstrate flight handling characteristics at high angle-of-attack (alpha) of 65–70 degrees using thrust vectoring vanes."F-18 High Alpha Research Vehicle (HARV) fact sheet."
