ABSTRACT
Computer models have been developed to translate cruise performance information into a fleet-planning model that is used in determining future aircraft acquisition requirements, aircraft assignment requirements, financial requirements, and operating conditions over various planning periods. From an individual airline's standpoint, the aircraft selection process is an ongoing function coordinated by a generalist group, such as corporate planning, with major help from technical, or specialist, administrations such as finance and property, marketing, line maintenance, engineering and maintenance, and flight operations. The aircraft evaluation process can be broken down into five areas: consideration of design characteristics, physical performance, maintenance needs, acquisition costs, and operating economics. Acquisition costs include the cost of the aircraft itself plus spare parts, ground equipment needed, maintenance and flight training required, and the cost of the money itself if the aircraft is to be financed through debt financing or equity financing.
