To reduce influence of lightning by keeping an airframe attitude that is less likely to receive lightning.SOLUTION: An aircraft 1 of the invention includes: a cloud position acquisition part that acquires a position of a cloud CL; an electric field direction estimation part that estimates an electric field direction when passing through the vicinity of the cloud on the basis of the acquired position of the cloud and a flight path 80; an attitude derivation part that derives a target airframe attitude to reduce the possibility of lightning on the basis of the estimated electric field direction; a path derivation part that newly derives flight paths 81, 82 and 83 so as keep the derived target airframe attitude in the cloud; and an attitude control part that controls an attitude of the aircraft so as to be the derived target airframe attitude when passing through the vicinity of the cloud.SELECTED DRAWING: Figure 14
【課題】落雷の可能性が低い機体姿勢とすることで落雷の影響を抑制する。【解決手段】本発明の航空機1は、雲CLの位置を取得する雲位置取得部と、取得された雲の位置と飛行経路80とに基づいて、その雲の近傍を通過するときの電界方向を推定する電界方向推定部と、推定された電界方向に基づいて落雷の可能性を下げる目標機体姿勢を導出する姿勢導出部と、雲において、導出された目標機体姿勢を保持できるように、改めて飛行経路81、82、83を導出する経路導出部と、雲の近傍を通過するとき、導出された目標機体姿勢となるように航空機を姿勢制御する姿勢制御部と、を備える。【選択図】図14
