Due to the inertia of jet engines, precise manual airspeed control is a demanding task. Accurate airspeed control is absolutely inevitable during air-to-air refuelling due to the close proximity of two aircrafts. In manual flight, the pilots workload may increase considerably, and could be well reduced by the use of automatic flight control. In that case, due to their fast aerodynamic reaction in producing drag and directly affecting the airspeed, speed brakes have a potential improve the performance of automatic airspeed control functions for this mission type. The object of the paper is to propose two flight control law designs that automatically incorporate the speed brakes in the airspeed control law to reduce the pilot workload in high precision maneuvers. This is done by utilizing the fast dynamics of the speed brake to eliminate or compensate for the engine lag. The two control laws are implemented and compared in the paper by means of flight simulator tests. The results indicate a improvement of the handling qualities.
