Page 9-1 ; To avoid confusion, it should be noted that the two "uni crossed at 45 degrees along the entire span" comment on the TOP WING layout refers to the 8 arrows crossed at 45 degrees on the TOP WING layout. In general one arrow is used for each ply of glass, therefore, the 8 arrows should be changed to only 2 arrows, each at 45 degrees to the trailing edge of the wing. See the bottom wing picture for the correct picture.
