Research and Validation on Evaluation Requirements for Flight Simulator Full Stall Model at High Angle of Attack

In this paper, full stall model at high angle of attack was studied and analyzed for flight simulator extended envelope flight training and recovery function, based on this study, stall characteristics, stall identification characteristics, high angle of attack modeling and objective test of stall characteristics, icing influence on stall characteristics for flight simulator extended envelope evaluation requirements were proposed. Some flight tests and experimental validations were carried out to validate the evaluation requirements proposed for full stall model at high angle of attack, using A320 flight simulator platform which data package meets FAA 14 CFR Part 60 requirements. The test and validation results show that, flight simulator can realize various test functions proposed in evaluation requirements, test results can reflect compliance between stall characteristics and evaluation requirements, the evaluation requirements proposed for full stall model at high angle of attack are reasonable and feasible.
