4Security-Fuel Tank Inerting Background Civil transport aircraft are now subject to what was once only a military threat –MANPADS and Small Arms (Man Portable Air Defense System)Their proliferation has resulted in numerous shoot-downs and close-calls involving civil passenger aircraft.From , 585 passengers and crewmembers of commercial transport aircraft died from MANPADS missile attacks. The attacks brought down 24 aircraft and severely damaged 10. (1) .They have long reach to arriving/departing aircraftKey to the threat is the difficulty of securing the 100 or more square miles of land surrounding civil airports. (2)They use the fuel system against the aircraftThe explosion of a 2 lb MANPADS warhead or impact effects of small arms can induce a far larger explosion of fuel tanks. Moderate damage can be magnified to make the aircraft unflyable.Countermeasures to throw off guidance systems are limitedCountermeasures can be defeated Small arms operate without automatic guidance1.
