12.+Diherdral+Angle

=
//The dihedral is the angle between the two wings, it is to improve it's stability.The Dihedral angle is the angle that each wing makes with the horizontal. The whole purpose of the Dihedral angle is to improve the lateral stability. If a disturbance cause one of the wings to drop, the unbalanced forces produces a sideslip in the direction of the down-going wing. This will cause a flow of air in the opposite direction of the sideslip. This Flow of air will strike the lower wing at a bigger (greater) angle of attack than it strikes the upper wing. The lower wing will receive more lift and the airplane will roll back into its proper position.//=====
