Just some interesting info that somehow fits in this debate
Boeing and USAF will have to recertificate entire F-15SA flight envelope
"The entire F-15 flight envelope requires clearance for the F-15SA fly-by-wire system," the USAF says. "The flight test to certify airworthiness will take approximately a year and a half to accomplish."
True fly-by-wire is a departure from the traditional F-15 hybrid electronic/mechanical flight control system. Previous incarnations of the jet were equipped with a dual-channel, high-authority, three-axis control augmentation system superimposed on top of a hydro-mechanical system.
