摘要：A flight management system comprises means (10) apparatus for aircraft,characterised in that it comprises means (10) for generating a function of direct operatingcost (DOC) versus arrival time in accordance with a range of cost index values,means (49)for storing a function of arrival time error cost (AEC) versus arrival time error,means (52)for combining said DOC function with said AEC function to provide a function of totalflight cost versus arrival time,means (53) responsive to the total flight cost function fordetermining the minimum thereof to provide an optimum arrival time signal,means (55)responsive to the optimum arrival time signal for providing an optimum cost index signalcorresponding thereto,speed generator means (11) responsive to the optimum costindex signal for generating an airspeed signal corresponding thereto in accordance withminimum direct operating cost,predictor means (13) responsive to the optimum costindex signal for generating a predicted arrival time signal in accordance therewith,andspeed adjuster means (24) responsive to the optimum arrival time signal, thepredicted arrival time signal and the airspeed signal for adjusting the airspeed signal inaccordance with the difference between the optimum arrival time signal and thepredicted arrival time signal to provide an airspeed command signal for controlling theairspeed of the aircraft.
