ABSTRACT:
A shield of rigid sheet metal is of a size and shape to substantially cover the instrument panel of an aircraft. A pair of shrouds on the bottom of the shield are spaced so that each fits over one of the control columns of the aircraft, and aligned holes in each shroud are adapted to receive a padlock to lock the shield in place. The shrouds are of a length to fit closely over the control columns when fully extended to prevent any significant movement of the control column axially and pins, which are secured to the shield, extent through openings in the control columns to prevent any accidental or unauthorized turning. A cylindrical housing open at one end is received over the throttle control, and a lock stem extending vertically from the housing is received in a tube, which is fixed to the shield, when the shield is possitioned on the instrument panel so that there can be no manipulation of the throttle.
