Supersonic aircraft have what some call Q-Feel systems that adjust the flight control pressures such that there is not a radically different amount of control movement and back-pressure for different airspeeds and altitudes. The F-106 also had a system that sensed when Mach 1 was exceeded by comparing total versus static pressures (and for a given Mach number that ratio is the same for all altitudes, I have worked the equations to make sure) at which point fuel was pumped between tanks in order to maintain the same CG when the center of pressure shifted. This improved performance when the aircraft was scrambling to intercept a hostile target by keeping the pilot from having to adjust to the center of pressure change brought on by going supersonic. ,
