PROBLEM TO BE SOLVED: To effectively use regenerative electric power of an electric motor generated when using the electric motor that is used as a power source in taxiing and running in take-off of an aircraft, as a braking source in landing.SOLUTION: An electrically-driven taxiing system for an aircraft supplies regenerative electric power generated in an electric leg motor used for electrically-driven taxiing of an aircraft 1 to an electric actuator for spoilers 9a, 11a and nacelle covers 13a, 15a driven in landing or starter generator that is driven in re-take-off following landing, whereby the regenerative electric power is effectively consumed and effectively used.SELECTED DRAWING: Figure 1 【課題】航空機のタキシングや離陸時の滑走の際に動力源として用いる電動モータを着陸時の制動源として利用する際に発生する電動モータの回生電力を有効活用する。【解決手段】航空機１のタキシングを電動で行うのに用いる電動脚モータに着陸時に発生する回生電力を、着陸の際に駆動されるスポイラー９ａ，１１ａやナセルカバー１３ａ，１５ａの電動アクチュエータ、あるいは、着陸時に続く再離陸時に駆動されるスタータ・ジェネレータに供給する。これにより、回生電力を効率よく消費させて有効活用する。【選択図】図１
