ABSTRACT:
A synthetic speed stability subsystem for maintaining the speed and phugoid stability of an inherently unstable aircraft is connected to a main flight control system. The speed stability subsystem uses the pitch and roll angles, and the equivalent air speed of the aircraft for calculating a synthetic speed stability signal, which is fed to the main flight control system, for controlling the stability of the aircraft.
