It might take, for example: 35 minutes to clean a plane 15 minutes to refuel a plane 10 minutes to load the passengers 30 minutes to load the cargo Assuming the above are done consecutively, minimum plane turnaround time is: 35 + 15 + 10 + 30 = 90 However, cleaning, refueling and loading the cargo can be done at the same time.
它可能需要例如： 35分钟清洁飞机 15分钟给飞机加油 10分钟装载旅客 30分钟装载货物 假设上述流程是逐个完成，最少需要时间： 35 + 15 + 10 + 30 = 90 分钟 不过，清洁、加油和装载货物可以同时进行。
