To provide a take-off landing support device, which is comparatively simple in structure, costs low, and can be easily operated, and by which an accident during flight can be hardly caused, high safety can be secured, and the advantage of transport, storage, inspection and maintenance can be considered, and take-off/landing and work preparation can be quickly performed so as to improve the operation efficiency remarkably.

A flight working machine 10 has an airframe 12 comprising a longitudinal side part and a lateral side part which are connected to each other in such a manner that the front view or the side view presents a substantially T-shape. In this arrangement, there are provided a first support part 91 for supporting one end side of the lateral side art and a second support part 92 for supporting the other end side, and the airframe 12 is supported substantially horizontally in the state of being floated from the ground by the first support part 91 and the second support part 92.
