PROBLEM TO BE SOLVED: To predict aircraft engine behavior.SOLUTION: Historical aircraft data recorded during flight associated with a plurality of aircraft engines and a plurality of prior aircraft flights is accessed, metrics from the aircraft data recorded during flight is automatically calculated on a per-flight basis, and a probabilistic model is employed to capture and represent relationships on the basis of the calculated metrics, the relationships including a plurality of engine parameters and flight parameters. Conditional probability distributions are then calculated for a particular aircraft engine during a potential or historical aircraft flight on the basis of the probabilistic model, engine parameter values associated with the particular aircraft engine, and flight parameter values associated with the potential or historical aircraft flight, and indications associated with the calculated conditional probability distributions are displayed.SELECTED DRAWING: Figure 1

    【課題】航空機エンジンの挙動を予測する。【解決手段】複数の航空機エンジンおよび複数の以前の航空機フライトに関連付けられた、フライト中に記録された履歴航空機データにアクセスし、フライト単位で、フライト中に記録された航空機データから基準を自動的に計算し、確率モデルを利用して、計算された基準に基づき、複数のエンジンパラメータおよびフライトパラメータを含む関係性を捉えて表現する。更に、確率モデル、特定の航空機エンジンに関連付けられたエンジンパラメータ値、および潜在的な航空機フライトまたは履歴航空機フライトに関連付けられたフライトパラメータ値に基づいて、潜在的な航空機フライト中または履歴航空機フライト中に、特定の航空機エンジンのための条件付き確率分布を計算し、計算された条件付き確率分布に関連付けられたインジケーションを表示する。【選択図】図1
