(b)
Dihedral angleL(left)isformedby twointersecting verticalplanes,the .rstparallel to the longitudinal axis of the rotorcraft, and the other at 110 degrees to the left of the .rst, as viewed when looking forward along the longitudinal axis.
(c)
DihedralangleR(right)isformedbytwointersecting verticalplanes,the .rstparallel to the longitudinal axis of the rotorcraft, and the other at 110 degrees to the right of the .rst, as viewed when looking forward along the longitudinal axis.
(d)
Dihedral angleA(aft) isformedby twointersecting verticalplanes making angles of 70 degrees to the right and to the left, respectively, to a vertical plane passing through the longitudinal axis, as viewed when looking aft along the longitudinal axis.
