摘要： Security apparatus and a method for preventing theft or unauthorized removal of instruments from the cockpit instrument panel of an aircraft and for preventing theft or unauthorized use of the aircraft. The apparatus includes a rigid plate substantially covering the instrument panel and two rigid arms pivotally secured to the plate inwardly of the columns respectively and laterally pivotable rearwardly away from and forwardly toward the plate. Each of the arms include an end portion for restrainably engaging the aircraft flight control yokes against rotation when the arms are pivoted to extend rearwardly away from the plate while the columns are fully rearwardly extended and the yokes are fully rotated to one side. A locking device is engageable with the end portions of the arms for locking the arms rearwardly extended and for cooperating with the yokes to prevent forward displacement of the columns while securing the plate against the instrument panel.
