An environmental fatigue loading standard was developed. It represents the mechanical loading and the environmental service conditions expected for wing root area structure of fighter aircraft. The standard, called ENSTAFF, utilizes the mechanical loading sequence FALSTAFF and connects defined temperatures to each peak and trough load on the basis of flight missions. It also includes rules for moisture conditioning and moisture control to account for the water picked up by the plastic matrix primarily during ground storage. The load and evironment sequence of ENSTAFF is presented in a form ready for application.
