The visual simulation of aircraft load spectrum is an important means to identify the maneuverability of aircraft and validate the validity of the measured data.According to the different data structure of the measured data source of the aircraft, a data storage method of logical data channel is proposed to solve the problem that different measured objects form Different structure of the data source differences; for large data volume measured data flight simulation simulation model performance problems caused by the establishment of the physical channel and logical data channel analysis model; based on data double buffering and drawing double-buffering mechanism to build a Aircraft model and real-time data simulation system environment, the experimental data of different test aircraft were analyzed and verified.The vision system completely meets the verification of Gigabyte-level load spectrum flight test data and maneuver recognition Requirements, complete reproduction of the entire flight history, the aircraft flight recognition maneuver movement, data validation and data validation provide a visual platform.
