FS – Fuselage stations are distances from a point in front of the helicopter nose. The first station is zero (0.00). WL – Waterlines are distances from a point below the helicopter. They follow the centerline. CL – Centerline is an imaginary line that passes through the center of the helicopter. The centerline runs from the nose to the tail. BL – Buttlines are distances from the centerline. They start at the centerline and show the distance to each side of the helicopter. Buttlines will be either to the left or right side. These dimensions help you find any point on the helicopter. Each point shown on the next page is a part of the helicopter you can see. GO TO NEXT PAGE
