It is getting more and more important for an aircraft manufacturer to
recognize the operators profit to achieve good products. The fuel system
architecture of a long range aircraft with two engines has been used, to
represent an example of the components needed to achieve the main
functions required from a fuel system. System specific parameters such
as price, weight, maintenance costs and power consumption have been used
to evaluate the operating costs. A risk analysis tool has been used to
evaluate the impact of uncertain input data on the system direct
operating cost, using the monte carlo simulation. Direct operating cost
breakdowns were produced down to component level. This emphasized, which
costs or components are the main drivers of direct operating costs of a
fuel system and could be used to focus future efforts to reduce such
costs. Therefore this book is adressed to aircraft and system designers
and all other people interested in aviation.
