The accurate and precise measurement of aircraft weight and center of gravity (CG) is a demanding task in the aviation industry. To that end, a group of Cessna employees was challenged by a member of its Senior Leadership Team (SLT) to improve the in-house weighing process. Through multiple initiatives, Cessna Aircraft Company has developed and patented the most accurate aircraft CG measurement system in the industry. In order for the system to work, Cessna engineers developed and copyrighted a sophisticated software package. The presentation will show how the team designed, developed, and implemented the Weight on Wheels (WoW) software package. The topics of ongoing and future software development will also be discussed.
