FEMAS: A Method to Establish Workload Evaluation Scenarios in Aircraft Certification Phase

Pilot workload has always been one of the most crucial safety-related factors in flight. In airworthiness regulation, the minimum flight crew in flight deck should be determined based on the workload on individual crew members. In order to establish the comprehensive flight scenes to demonstrate the workload, a method called FEMAS was proposed, which including five dimensions (FHA based, experience of similar models, abnormal procedures, MMEL requirements, and specific environment conditions) and one integration process. The method was implement in one type of aircraft airworthiness certification phase, and 27 scenarios were determined to be carried out in total.
