本文提出了一种新的爬升程序，称为渐进爬升程序。当飞机爬升到巡航高度或改变飞行高度层时，通常会施加最大爬升推力。然而，与巡航推力相比，该最大巡航推力会导致更高的燃油消耗，从而导致非燃油最佳爬升率更高。存在最小化燃料消耗的最佳爬升率，但飞机通常选择更快的爬升率。本文重点关注巡航高度之前的爬升阶段部分，并通过数值模拟阐明了燃油消耗与爬升率之间的关系。作者还考虑了实际空中交通管制限制和飞行员操作，提出了实用的节油爬升程序。预计节省的燃油约为 50 磅，相当于巡航总燃油消耗的 0.1%。然而，拟议的程序将适用于全球几乎所有飞机和航班，因此累积效应将是显着的。此外，对空中交通管制和飞行员的负面影响较小，因此所提出的渐进爬升程序可以在不久的将来的运行中应用。关键词组件；轨迹优化、爬升轨迹、爬升、爬顶

This paper proposes a new climb procedure called a gradual climb procedure. When aircraft climb to the cruise altitude or change the flight level, maximum climb thrust is usually applied. However, this maximum cruise thrust leads to a higher fuel consumption compared to the cruise thrust, which results in non fuel optimal higher climb rate. An optimal rate of climb which minimizes the fuel consumption exists, but aircraft usually opt for a faster rate of climb. This paper focuses on the part of the climb phase just prior to the cruise altitude, and clarifies the relationship between fuel consumption and the rate of climb via numerical simulations. The author also proposes a practical fuel-saving climb procedure considering actual air traffic control constraints and pilot operation. The expected fuel saving is of the order of 50 lb, which corresponds to 0.1 % of total cruise fuel consumption. However, the proposed procedure will be applicable to almost all aircraft and flights worldwide, so the cumulative effect will be significant. In addition, the negative effects to air traffic control and a pilot are minor, so the proposed gradual climb procedure can be applied in the near future operation.
