Over the many decades of commercial airplane, development designers have focused on minimizing the maximum take‐off weight (MTOW). This chapter demonstrates the sensitivity of the airplane's all‐up weight (AUW) to the flight efficiency, thereby emphasizing the importance of the lowest possible drag and high propulsive efficiency in cruising flight. It presents the unity equation that states that the sum of all basic weight fractions contributing to the MTOW equals one. The MTOW of a commercial transport is typically determined by the design mission range that can be traveled with the design payload. The total amount of fuel when taking off consists of mission fuel weight and reserve fuel weight. A high productivity forms an important factor to increase the potential operational profit. The chapter demonstrates that, for a given MTOW, there exists a stretch of design mission ranges for which the productivity has a (near‐)maximum value.
