Abstract
A cockpit internal anti-sabotage system (CIASS) without compromising the cockpit security and the present anti-hijacking procedure and protocol, wherein a single cockpit crew alone in the cockpit cannot deny bonafide entry of other cockpit crew or cabin crew in an attempt to commit suicide or sabotage the aircraft, the system comprises a manual door lock system and an automated door lock system wherein both the systems comprising a mechanical system or a non-mechanical system or combination of both.
Claims20
A Cockpit Internal Anti Sabotage System (CLASS), the system comprising:
- a door lock system for a door of the cockpit, the door lock system having an auto position, an open or allow position and a deny or close position wherein the auto position enables emergency access to the cockpit by entry of a code in an electronic pad positioned outside the cockpit, keeping the cockpit accessible to able bodied passengers, cabin crew and sky marshals in case of emergencies by means of external keypad, and the deny or close position prevents opening of the door from outside the cockpit;
- wherein the Cockpit Internal Anti Sabotage System further includes a pair of control buttons or levers operatively coupled to the door lock system;
- wherein the door lock system and the pair of control buttons or levers are operatively coupled such that movement of the door lock system to the deny or close position is prevented unless any one or both control buttons or levers of the pair of control buttons or levers are actuated and held in the actuated position;
- wherein each of the pair of control buttons or levers is located in the cockpit remote from the actuation means of the door lock system and spaced apart from each other so that a single person using two hands is unable to actuate the door lock system to the deny or close position;
- and
- wherein inability of a single person to actuate the pair of control buttons or levers and hold them in actuated position while moving the actuation means of the door lock system to the deny or close position prevents internal sabotage of an aircraft by a cockpit crew by locking himself in the cockpit and denying bonafide entry of other cockpit crew or cabin crew into the cockpit.

A Cockpit Internal Anti Sabotage System (CIASS) for an aircraft, the system comprising:
- a door lock system for a door of the cockpit, the door lock system having an auto position, an open or allow position and a deny or close position wherein the auto position enables emergency access to the cockpit by entry of a code in an electronic pad positioned outside the cockpit, keeping the cockpit accessible to able bodied passengers, cabin crew and sky marshals in case of emergencies by means of external keypad, and the deny or close position prevents opening of the door from outside the cockpit;
- and
- a pair of control buttons or levers operatively coupled to the door lock system, wherein the door lock system and the pair of control buttons or levers are operatively coupled such that movement of the door lock system to the deny or close position is prevented unless any one or both control buttons or levers of the pair of control buttons or levers are actuated, and held in the actuated position;
- wherein each of the pair of control buttons or levers is located remote from actuation means of the door lock system and spaced apart from each other such that a single person using two hands is unable to actuate the door lock system to the deny or close position;
- and
- wherein the system is integrated with automated system of the aircraft including aircraft's height altimeter or radio altimeter, and wherein the system deactivates the electronic pad at the time of takeoff and at the time of landing for an altitude of 0-2500 feet from the ground level, and reactivates the electronic pad upon crossing altitude of 2500 feet and on touching the ground respectively.
