Research progress and development considerations on load flight test of transport aircraft

Load flight test is one of the important projects for the approval flight test of transport aircraft. The flight test team has accumulated rich experience through multiple model flight tests, and has made significant progress in the technical fields of load flight test, safety monitoring based on measured loads, and model-based load flight testing. However, facing the future development trend of transportation aircraft, it is still necessary to continue conducting research on load flight test technology to further improve the effectiveness, safety, and economy of load flight test.
