Abstract

A method for controlling an aircraft in an aircraft hijacking situation to prevent unauthorized control over the aircraft to be performed. The method is especially characterized in that a person intended to perform authorized control over the aircraft, such as the pilot of the aircraft, activates a different control system which puts at least a part of the ordinary control system out of function.

Description

Method for controlling aeroplanes
Technical field
The present invention relates to a method for controlling and maintaining control over an aircraft.
Specifically, the invention relates to a method for preventing aircraft hijacking.
Background
Known systems for controlling aircraft are manual as well or automatic, so-called autopilot. In addition to this there are systems, by means of which aircraft can be controlled from the ground.
Control over an aircraft in the air belongs to the pilot and the corresponding, which control can be performed via a manual system and an autopilot.
In a hijacking situation the control is taken from the pilot or the corresponding.
Summary of the invention
One object of the present invention is to offer solutions to the problem of eliminating the possibilities to, thus, perform unauthorized control over an aircraft.
This object is obtained by the method characterized by features according to the characterizing portion of the attached claim 1.
Preferred embodiments are specified in the respective dependent patent claims. Detailed description of the invention
Thus, the method according to the invention has the purpose to prevent e.g. that hijacked aircraft can reach the intended goal, e.g. as took place September 11, 2003.
In short the method includes a combination of a remote control performed from the ground by means of an apparatus specified here of the mechanical steering mechanism used in the aircraft as well as the autopilot installed in the aircraft, which can put the mechanical steering mechanism out of function. This can take place in dif- ferent ways, e.g. by explosives installed in the aircraft, which explosives when detonated mechanically prevents the use of the mechanical steering mechanism. A different computer program is exchanged for the computer program normally used during the flight and makes it possible to take over the control from the normal control program.
The apparatus used make possible a locking of the computer control of the aircraft to the aircraft course used in the computer program. The locking may, preferably, be unlocked only by the transmitter used in the program, e.g. the transmitter on the airport to which the aircraft is destined or the corresponding landing track.
The remotely controlled program described above is performed by known technique.
The invention does not infringe the security of the aircraft staff and passengers.
According to an embodiment preferred in certain cases, the course of the aircraft is changed also in the case of no autopilot installation in the aircraft, so that the course follows a control program transferred from the ground and/or controlled different control program, which excludes every other program and which control cannot be changed by any other than the station that transmits and or controls the control program now mentioned. Also according to an embodiment preferred in certain cases the change of the course of the aircraft so that the course follows a different control program directed from e.g. the ground at e.g. a terrorist attack
- either by means of an EMERGENCY control installed in the pentry of the aircraft, which control preferably is located by the ordinary ALARM button, hidden for the passengers,
- or by means of an EMERGENCY control installed in the cockpit within reach for the pilot.
Both EMERGENCY controls have simultaneous action if any of them is activated.
The method according to the invention also comprises automatic closing of a slide door installed especially for this purpose, which door shields the cockpit from the rest of the aircraft. The door is preferably manufactured of hardly compressed plastic with the same hardness as steel or higher degree of hardness than that of steel, e.g. of a plastic of the same type as is used for spaceships according to american standards.
This door may according to one embodiment also be closed manually from the cockpit according to the orders of the pilot e.g. before the flight starts. It is opened in the corresponding way e.g. after the termination of the flight.
When the EMERGENCY controls are activated the above referenced different com- puter program starts to operate at high speed according to the following
- the course of the aircraft is changed as specified above;
- the door to the cockpit is closed; - the light in the aircraft is put out;
- the catapult chairs in the cockpit are prepared for use;
- further measures are made, the measures having been programmed in order to match the security demands.
According to an embodiment preferred in certain cases laughing gas, N20 (dinitro- genoxide) gas, is introduced into at least the passanger compartment when the EMERGENCY control or the corresponding is activated.
According to an embodiment preferred in certain cases the change of the course of the aircraft is, as mentioned, activated by activation of any of the EMERGENCY controls installed in the aircraft, either in the pentry or the cockpit.
A further possibility to activate the change of the course of the aircraft according to the invention comprises providing the steering wheel or the corresponding wheel in the aeroplane with a built-in contact which during the flight shall be kept pushed in by the pilot.
At a block-out of the pilot or disability for other reasons to continue to control the aircraft - death or insufficiency e.g. due to total or reduced ability in a medical meaning - the EMERGENCY alarm is activated when the pressure from the hand of the pilot disappears.
According to another embodiment of the invention the invention is applied to some other kind of vehicle than an aircraft, such as a ship, a bus or similar vehicle.

Claims

1. A method for controlling an aircraft in an aircraft hijacking situation to prevent that the control over the aircraft can be performed unauthorized, characterized in that a person intended to perform authorized control over the aircraft, such as the pilot of the aircraft, activates a different control system, which puts at least a part of the ordinary control system out of function.
2. A method according to claim 1, characterized in affecting the steering mecha- nism of the aircraft by a e.g. on the ground arranged remote control device so that said mechanism cannot be used as intended.
3. A method according to claim 1 or 2, characterized in putting the normal mechanical steering mechanism out of function by means of mechanical impact, e.g. by means of explosives.
4. A method according to claim 1, 2 or 3, characterized in that the course of the aircraft is changed also in the case of no autopilot installed, so that the course is controlled by a e,g, from the ground transferred and/or controlled different con- trol program, which excludes any other control program and preferably cannot be changed by any other that the transmitter that transfers said different control program.
5. A method according to claim 4, characterized in that the change of the course of the aircraft by said different control program is activated
