摘要

一種被應用於飛機在巡航飛行時，檢測飛行操縱面不正常操作的監測方法以及預估飛機飛行燃油消耗過量的不規律差異分析方法。該方法是利用飛航操作品質保證（FOQA）計畫中之快速存取記錄器(QAR)所獲得飛行後之飛行數據資料。本研究採用模糊邏輯建模(FLM)技術，建立標準的飛機升阻比(L/D)模型。飛行操縱面的不規律差量可藉由分析預測精確之升阻比(L/D)模型檢測得到結果。升阻比L/D的差異量可藉由預測之偏差量以及與升阻比L/D所有相關聯影響衍生之飛行參數的泰勒級數展開偏差量求得。經過驗證改良後的不規則差量亦可以改善潛在的省油結果。經由過量的燃料成本分析和非週期性維修成本的判斷，本研究將可以提出飛行操縱面的最佳化調校時間間隔。目前所提出之觀念是一項改善航空公司的飛行資料分析以及提升飛航品質操作之創新方法。

A monitoring method is employed to examine the abnormal flight control surfaces in cruise flight and to predict the excessive fuel consumption due to the effects of irregular deviations. This method utilizes the post flight data in quick access recorder (QAR) available in the Flight Operations Quality Assurance (FOQA) program. The fuzzy-logic modeling (FLM) technique is employed to establish the standard lift-to-drag (L/D) model. The irregular deviations of flight control surfaces are examined by the L/D model-predicted results through sensitivity analysis. The contribution values in L/D deficiency are predicted by the deviations and the L/D derivatives of all influencing valrables in Taylor series expansion. The estimations of potential fuel saving after irregular deviations being improved are demonstrated in this paper. The optimum time interval for flight control rigging is suggested based on the judgment of excessive fuel cost and unscheduled maintenance cost. The present concept is an innovation to improve the flight data analysis of FOQA program for airlines.
