Further, given that dihedral diminishes gliding performance, its infrequent use suggests that a premium is placed on maximizing lift to drag ratio (that is, maximizing efficiency) during gliding.
In each test, we compared simulations guided by the wriggling algorithm to ones guided by a standard thrashing algorithm in which the dihedral angles are varied independently.
I then fought through a bush around an overhang, and then ran it out over a short slab to a small ledge at the base of an easy looking dihedral .
Leading the way, I arrive at a small tree that has somehow found a footing in the steep dihedral about seventy feet above the ground.
This problem was countered by incorporating 15 degrees of dihedral in the horizontal tail, which initially had been virtually dead flat.
