本报告包含生命周期成本要素和关键ECS成本因素的背景信息。生命周期成本的要素是从初始设计阶段到运营使用定义的。讨论了ECS设计如何影响飞机总成本的信息和影响ECS成本的主要因素的信息。概述了基于LCC比较ECS设计的关键步骤或工作。简要描述了两个用于估计总飞机程序的LCC的计算机程序及其在估计ECS LCC中的用途。

This report contains background information on life cycle cost elements and key ECS cost factors. Elements of life cycle costs are defined from initial design phases through operational use. Information on how ECS designs affect overall aircraft cost and information on primary factors affecting ECS costs are discussed. Key steps or efforts for comparing ECS designs on the basis of LCC are outlined. Brief descriptions of two computer programs for estimating LCC of total aircraft programs and their use to estimate ECS LCC, are included.
