Abstract

During the early design phases of new aircraft programs, it is desirable to have an established ''value of a pound'' to use as a guide for making decisions that contribute to the optimum weight, cost, and life cycle cost of the aircraft. The objective of this paper is to present a procedure for establishing preliminary ''value of a pound'' guidelines for use during preliminary design and the early design development phase of aircraft programs. Aircraft flyaway unit cost and the operational life cycle fuel cost resulting from variations in aircraft weight are necessary to establish the value of a pound for both military and commercial aircraft, This approach includes a quick and easy method for estimating aircraft development cost, unit flyaway cost, recurring cost per pound of aircraft structure, life cycle fuel cost, and the effect of weight on life cycle fuel cost.
