手工计划模拟CDA燃油的节省

飞机在飞行中,普遍采用的阶梯下降程序,这需要航空器频繁改变推力、增加下降角度和调整高度,这样加大了飞行员和管制员的工作压力,同时对最后阶段飞行的油量也有增加。通过对连续下降进近（CDA）的现状进行分析,给出连续下降进近相对传统进近方式的优势,并结合航空公司手工飞行计划制作的方法及原理对连续下降进近在最后阶段飞行时间和燃油方面的节约进行验证。

Simulating the Saving of CDA Fuel through Manual Plan

Planes generally adopt the stepped down descent program in flying, which requires that aircraftfrequently change thrust, increase descent angle, and adjust height. This increases the working pressure of pilots and controllers, and also oil consumption at the final flying stage. Through the conclusion of CDA status and the brief introduction to related concepts, the paper offers advantages of CDA over traditional ways, and verifies the savings of time and fuel in the final flying stage by CDA according to the methods and principles of working out flying plans manually.
