Title:Environmental Control Systems Life Cycle Cost
Issuing Committee:Ac-9 Aircraft Environmental Systems Committee
Scope:The purpose of this document is to provide qualitative information on life cycle cost (LCC) aspects of environmental control systems (ECS) design. 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.【英文标准名称】:Glassinbuilding-Determinationofthermaltransmittance(Uvalue)-Calculationmethod
