A minimum spacing must be maintained when two consecutive aircraft take off from a runway to avoid impact of the wake vortex generated by the leading aircraft. The minimum required space depends on the aircraft types of the two aircraft. Consider six aircraft waiting to take off and sequence their tale-offs to minimize the total amount of such spacing. The data are given in the template entitled
