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: an electric field sensor 22 that detects electric field intensity at different positions in the aircraft 1; an electric field direction estimation part that estimates an electric field direction 62 on the basis of a detection result obtained by the electric field sensor 22; 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 62; and an attitude control part that controls an attitude of the aircraft so as to be the derived target airframe attitude.SELECTED DRAWING: Figure 5
【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、航空機1における異なる複数の位置の電界強度を検出する電界センサ22と、電界センサ22の検出結果に基づいて電界方向62を推定する電界方向推定部と、推定された電界方向62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、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5
