本研究應用國際上最新發展之「人為失誤預測模組（Human Error Template，HET）」，分析IDF戰機在降落階段時可能會誘發飛行員犯錯的潛在人為失誤之模式。HET是以檢查表形態，包含十二項錯誤模式，做為預測人為失誤之方法，並應用「階層任務分析（Hierarchical Task Analysis, HTA）」，將每一個任務所需執行的步驟分析到最底層，分析者必頇辨認出每一任務步驟潛在錯誤模式發生之機率，與對飛行安全影響程度之嚴重性。有44位飛行員參與本次研究，結果顯示HET檢查表具有良好的內部一致性信度，α係數分別介於.60至.85之間；另外，發現影響上述兩個任務步驟最大潛在風險因素為「忘記執行」、「任務執行不完整」、「重複執行任務」及「太晚執行任務」等4項錯誤模式，最後本研究以「V1.1.1檢查起落架指示器」之「重複執行任務」的錯誤模式為範例，以風險矩陣為概念，利用事件肇發可能性、嚴重度及風險水準（可能性與嚴重度相乘），嘗試建構軍事飛行風險評估指標，將HET導入飛安管理實務中，以確保飛行安全。

This research applies the latest formal technique for human error prediction--Human Error Template (HET)--to evaluate the potential risks of human errors in the IDF flight operations during approach and landing. HET is a checklist style approach to error prediction that comes in the form of an error pro forma containing twelve error modes. HET is applied to each bottom level task step in a hierarchical task analysis (HTA) of the task in question. The technique requires the analyst to indicate which of the HET error modes is credible for each task step, the probability of error and the criticality of error, based upon their judgment. A total of 44 fighter pilots participated in this study. This research finds that there was high reliability with α value between .60 and .85. The high likelihood of error modes committed by pilots during performing approach and landing include ‘Fail to execute’; ‘Task execution incomplete’; ‘Task repeated’ and ‘Task executed too late’. There is a rising need to investigate further impact to flight safety for such errors caused by understanding its criticality and likelihood for risk assessment. The research aims are to control the potential risks of human errors in the military operations and provide a basis for improving software and hardware design and tactic training to enhance flight safety.
