The purpose of flight test is to check whether the aircraft and system work normally in the flight envelope through specific flight test subjects,to verify whether the system parameters meet the design requirements,and to show the compliance of the corresponding airworthiness provisions to the airworthiness authority with the test results.Aiming at the problem that the fuel imbalance alarm oc-curred repeatedly in the fuel system of a civil aircraft during the adjustment flight test under specific working conditions,which caused heavy workload for the flight crew,special test procedures were designed for the ground test based on the analysis of the principium of fuel imbalance alarm,the ad-justment flight test data and the automatic control logic of fuel system.Finally,the cause of the fault was found and the corresponding troubleshooting measures were formulated,which provided a guar-antee for the subsequent flight safety.
