To provide methods of limiting an aircraft to a pitch axis envelope and, more specifically, methods of employing dynamic elevator command limits to control an aircraft to remain within a desired pitch axis envelope.SOLUTION: A method comprises: determining aircraft state limits associated with multiple pitch axis variables of an aircraft; determining predicted aircraft states; comparing the predicted aircraft states to the aircraft state limits to produce aircraft state errors; translating the aircraft state errors into a set of positive and negative limit elevator commands; selecting a highest priority positive limit elevator command; selecting a highest priority negative limit elevator command; limiting a primary pitch axis control law elevator command of the aircraft to a value that is less than or equal to the highest priority positive limit elevator command and greater than or equal to the highest priority negative elevator command; and controlling the aircraft according to the primary pitch axis control law elevator command limited to the value.SELECTED DRAWING: None

    【課題】航空機をピッチ軸エンベロープに制限する方法に関し、より詳細には、動的な昇降舵コマンド制限値を使用して、航空機を所望のピッチ軸エンベロープ内に留めるように制御する方法を提供する。【解決手段】航空機の複数のピッチ軸変数に関連付けられた航空機状態制限値を決定すること、予測される航空機状態を決定すること、予測される航空機状態を航空機状態制限値と比較して、航空機状態誤差を生成すること、航空機状態誤差を正及び負の制限昇降舵コマンドのセットに変換すること、最優先の正の制限昇降舵コマンドを選択すること、最優先の負の制限昇降舵コマンドを選択すること、航空機の一次ピッチ軸制御則昇降舵コマンドを最優先の正の制限昇降舵コマンド以下であり且つ最優先の負の昇降舵コマンド以上である値に制限すること、及びその値に制限された一次ピッチ軸制御則昇降舵コマンドに従って、航空機を制御する。【選択図】なし
