Method for calculating an optimum economy cruise speed in an aircraft and its use is disclosed herein. The method includes receiving a plurality of flight parameters including a weight of the aircraft, an aircraft bearing and an atmospheric pressure and temperature, a wind speed and a wind bearing at the altitude of the aircraft; calculating a cost index associated with the flight of the aircraft; calculating a weight coefficient of the aircraft, a cost index coefficient, a wind Mach number and an absolute value of a difference between the wind bearing and the aircraft bearing. Additionally, the method includes calculating an optimum Mach number of the aircraft, which provides the optimum economy cruise speed. The calculation of the optimum Mach number includes the weight coefficient, the cost index coefficient, the wind Mach number and the absolute value of the difference between the wind bearing and aircraft bearing.
