ABSTRACT:
A method and device for calculating a target speed of an aircraft may include a flight point time determining section that determines when the aircraft actually gets to a particular flight point, taking account of the aircraft's current target speed. A time interval calculating section calculates a time interval between the predetermined time at which the aircraft must get to the particular flight point and the determined actual time. A speed updating section updates the target speed and applies the updated target speed to the aircraft if the calculated time interval is greater than a duration of comparison, which is variable and depends on the actual distance so as to decrease when the actual distance decreases.
