Claims9
An apparatus for training aircraft pilots from a captive aircraft comprising:
- (a) a support mast including a top end provided with an articulation means defining a vertical axis and a horizontal axis;
- (b) a rigid boom mounted on the articulation means and extending outwardly therefrom for defining a small arm and a big arm;
- (c) a balance weight including a top and a base, the top of the weight being attached under the small arm and the bottom of the base being provided with rolling and stopping contact means for engaging the ground and limiting the pivoting amplitude of the boom about the horizontal axis during raising of the big arm;
- and
- (d) means carried by the big arm for suspending an aircraft at substantially its center of gravity, the suspending means including a first universal joint disposed adjacent the big arm and a second universal joint disposed adjacent the aircraft.
