Cost Estimating Relationships for Fixed Wing Aircraft; List Price versus Empty Weight

Abstract

This Cost Estimating Relationship (CER) for Fixed Wing Aircraft was developed to estimate the unit cost of a twin engine, commercial, turbo-prop aircraft procured off the shelf. The Army has a limited fixed wing capability and most of this capability is procured in a commercial environment instead of through a typical rotor wing procurement cycle. The list price in the commercial market includes both engines and standard avionics, while in a typical Government rotor wing procurement these items are Government Furnished Equipment. Therefore, this CER was developed using the parameter of empty weight and aircraft commercial list price. The data collected was analyzed using the Statistical Analysis System (SAS) on the AVSCOM Scientific and Engineering Computer System. The program developed is a linear regression of the form (y = a + bx), and the results are shown in the report.
