Problems solved by technology

[0002] At present, the testing and repairing of air data computers and air data instruments are carried out manually or returned to foreign manufacturers for repair. The maintenance period is long, the maintenance accuracy is low, the maintenance cost is high, the degree of automation is low, and human factors increase.
Even due to the low accuracy of manual repair, it brings flight safety hazards
In addition, the existing flight simulation and simulation systems lack air data computers, the air data is inaccurate, and the reliability cannot be guaranteed, resulting in large deviations in simulation effects, poor sense of reality, serious distortion, and even training results due to data distortion. Inconsistencies in the actual operation of the aircraft will bring hidden dangers such as flight safety
