Full-scale ground simulation test is an important and necessary mean which can ensure the validity and rationality of fuel system design,verify the unison of fuel system and its finished product performance, in time find design disfigurements and questions that theory and calculation unable to resolve,and eliminate system failures to sure that aircraft fly safely and reliably.Modern aircraft fuel system is more and more complex. Adopting new technologies not only put forward correspond reqirment for fuel system design but also bring many problems to its full-scale ground simulation test. In view of the characteristics of aircraft fuel system, the simulation methods of its test conditions and the designing maneuver of a great deal data computerized control system are expatiated. The test technologies have had successful applications in the developing of many types of aircraft,and have certain engineering value. 
