Generalized equations are presented for estimating the development and production costs of aircraft airframes. Provided are separate cost estimating relationships (CERs) for engineering, tooling, manufacturing labor, and quality-control hours; manufacturing material, development support, and flight-test cost; and total program cost. The CERs, expressed in the form of exponential equations, were derived by multiple least-squares regression analysis. They were derived from a data base consisting of 34 military aircraft with first flight dates ranging from 1948 to 1978. Most of the aircraft technical data were obtained from either original engineering documents such as manufacturers' performance substantiation reports, or from official Air Force and Navy documents. The cost data were obtained from the airframe manufacturers, either directly from their records or indirectly through standard DoD reports such as Contractor Cost Data Reporting system.
