Ergonomics 101 Ergonomics is a discipline focused on the design of tools and equipment so that they can be used safely, comfortably, and efficiently. The design of civilian and military aircraft makes extensive use of ergonomics. Some of the basic tools introduced in this chapter will enable us to solve many problems related to ergonomics, such as those involving the following requirements. • The U.S. Air Force requires that its pilots must have heights between 64 inches and 77 inches.
