The demand for business aircraft is very sensitive to price changes. An important part of the aircraft design process is the assessment of the market price for the new designs or model derivatives to determine their economic feasibility. This paper presents a method to be included in the aircraft design process which enables engineers to design to price. The method is based on a relationship between the aircraft market price and the value of the aircraft to the customers. The present work focuses on multi-engine turbine aircraft and involves nineteen aircraft attributes that are of value to business aviation customers to determine the aircraft market price.
