A Novel Quantified Method for Flight Operation Safety

According to actual QAR data which can reflect flight safety, a new method of flight operation safety on event margin was proposed. And a model for event margin was established based on flight safety monitoring standard. By quantitative analysis event margin of parameters, it can be used to evaluate flight safety, and it can help to reconstruct operation morphology. Furthermore, it widens research and application chances for FOQA. Experiment results show its efficiency.
