In a flight control system for an aircraft having three control surfaces, interconnected feedback control loops for stabilizing and optimizing the performance of the aircraft, the stabilizing loop comprising: first means for summing signals representing pitch rate and vertical acceleration of the aircraft; complementary filter means connected at its input to the pitch rate signal and a canard position signal for filtering these signals together to form a combined signal thereby reducing signal noise; second means for summing the combined signal and an output signal from the first summing means; filter means connected at its input to the output of the second summing means for providing lead compensation of the signal resulting at the output of the second summing means thus providing a lead compensated signal; means for obtaining an error signal between the lead compensated signal and a pilot command input signal; and parallel means distributing the error signal as respective stabilization error signals for the three controlled surfaces; means for integrating the stabilization error signal; and means for connecting the stabilization error signals to actuators of corresponding control surfaces.
