【 摘 要 】
The design service goal of commercial aircraft is defined by flight cycles, flight hours and calendar years, which affects aircraft structure weight, maintenance interval and operation economy. The design service goal is closely related to expected operation route. Two methods are applied to calculate three lengths of anticipated flights, including short, medium and long flight. Criterion of utilization rate and minimum design service goal are used to calculate flight cycles and flight hours. Sensitivity analysis of aircraft design service goal in regard to expected operation route shows that flight cycles depend on short flight and flight hours depend on long flight. Shorter route distance leads to larger flight cycles and more significant change per unit of route distance. Longer route distance leads to larger flight hours and there exists an approximately linear relation.
