Comprehensive evaluation of pilot operation procedures for commercial airliner

Mostly by an elaborate set of pilot operation procedures(POP) crew can control planes successfully. Pilot may operate wrong under the inconsistent or illogical procedures, which can cause accident in flight. Normal procedures of approach and landing phases which come from flight crew operations manual of the Boeing 737NG airplane were divided into task function flow, then the hierarchy of index system was confirmed. The comprehensive evaluation index system of POP in approach and landing phases was established by consulting in-service pilots with Delphi method twice. Index weight factors were calculated by order relation analysis. POP was evaluated by fuzzy comprehensive evaluation and evaluation scales and values were calculated by weight factors and evaluation matrixes. A POP comprehensive evaluation method was proposed with the integration of functional flow diagram, Delphi, order relation analysis and fuzzy comprehensive evaluation. The method was used in evaluation of Boeing 737NG airplane POP of approach and landing phases. The result indicate the validity and rationality of the comprehensive evaluation method.
