題 目：民用噴射客機遭遇危害天氣之縱向與橫向飛行品質評估
研 究 生：許溥宗
指導教授：何慶雄

本研究主要是想利用飛航資料記錄器之真實飛行資料進行性能分析。利用航機在危害天氣時的空氣動力係數和空氣動力導數透過飛行力學的運動公式進行縱向以及橫向飛行操作品質之評估，且不考慮駕駛補償。並利用縱向飛行操作品質常用評估參數的觀念，訂定一個新的橫向飛行操作品質的參數，並利用實際例子測驗此一參數的可行性。
本研究使用兩個案例:一架中型民航機在著地前橫向飛行操作品質，此案例經分析發現該機於落地前遭遇之側風變化量增加，橫向飛行操作品質及橫向運動阻尼降低，此可能增加該機組員落地過程中穩地定操控飛機壓力，造成該機落地過晚。並發展橫向CAP可作為航機在橫向運動之指標。一架大型民航機在下降期間遭遇亂流的事件測試縱向飛行操作品質的趨勢，可以觀察出該機在遭遇亂流時，縱向飛行操作品質從level 1降至level 3。

Title：Flying Quality Assessment for Civil Transport Aircraft Longitudinal and Lateral Motions under Weather Hazard

Student：Pu-Chung Hsu
Professor：Ching-Shiung Ho

The objective of the study is to analyze aircraft’s longitudinal and lateral flying quality under Weather Hazard by using real flight data in flight data recorder (FDR). Through the aircraft dynamics, we can assess vertical and horizontal flight operations quality by using aircraft's aerodynamic coefficients and aerodynamic derivatives in hazardous weather. And a new lateral flight quality index was applied by using the same concept of longitudinal parameter Control Anticipation Parameter.

There are two cases study: Case 1 is about the lateral flying quality assessment of a medium civil transport aircraft which encounters a cross wind before it touchdown.
The result can observe that when the crosswind variation increase cause the lateral flying quality level down. And the new lateral flight quality index is tested. Case 2 is about the longitudinal flying quality assessment of a heavy civil transport aircraft which encounters turbulence when descending. The result can observe that longitudinal flying quality degrades from level 1 to level 3 when encountering turbulence.
