PURPOSE: To improve the viewfield efficiency per window opening area and keep the excellent viewfield in the forward, upward and rearward directions, by forming a triangular window to a horizontal triangle whose one sides is positioned nearly vertical in the body longitudinal direction.
CONSTITUTION: Each of the left and right windows 22 and 22 in the rear upper part among the windows in a cabin room is formed to a horizontal triangular form. Accordingly, the horizontal triangular shape has the vertical front side in the advance direction as one side and the part between two other sides is narrowed to the opposite angle at the center in the rear part, and further an R is formed at each corner part of the triangle. Further, the position of the window 22 is at the position below the front edge of the wing root part of a main wing 3, and is installed in accordance with the position of the visual line of a passenger on the seat in a cabin room.
