Fire extinguishing system for an aircraft

Fire extinguishing and prevention device for an aircraft, comprising

• an On-Board-Inert Gas Generating-System (OBIGGS) unit comprising a device with an OBIGGS inflow port connected to a source of gas mixture, said gas mixture comprising an inert gas component, and an outflow port, said OBIGGS unit being adapted to separate said inert gas component out of said source of gas mixture and to provide said inert gas component to said outflow port,
• a first connector or a plurality of first connectors coupled to said outflow port for providing said inert gas component to a fuel tank or a plurality of fuel tanks, respectively, of said aircraft,
• characterized by a second connector or a plurality of second connectors coupled to said outflow port for providing said inert gas to at least one space selected from a cockpit space of the aircraft, a passenger cabin space of the aircraft, a cargo bay of the aircraft.

Method for preventing and extinguishing a fire on board of an aircraft during flight, comprising:

• producing an inert gas in an On-Board-Inert Gas Generating-System (OBIGGS) unit by supplying a gas mixture, said gas mixture comprising an inert gas component to an OBIGGS inflow port, separating said inert gas component from said gas mixture and providing said inert gas component to an outflow port,
• directing said inert gas component to a fuel tank of said aircraft
• characterized by the step of providing said inert gas to at least one target space selected from a cockpit space, a passenger cabin space and/or a cargo bay of the aircraft.

Use of an on board inert gas generating systems (OBIGGS) unit comprising a an OBIGGS inflow port connected to a source of gas mixture, comprising an inert gas component, and an outflow port, said OBIGGS unit being adapted to separate said inert gas component out of said source of gas mixture and to provide said inert gas component to said outflow port, for directing inert gas via an inert gas fire extinguishing line to a target space selected from a cockpit space, a passenger cabin space and a cargo bay of an aircraft for extinguishing a fire in said target space or preventing a fire to occur in such target space or hindering a fire from spreading out in such target space, wherein said inert gas produced by said OBIGGS unit is preferably further used for filling the ullage in a fuel tank of the aircraft.
