Security-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 1975-1998, 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 aircraft Key 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
aircraft The 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 limited Countermeasures can
be defeated
Small arms operate without
automatic guidance 1. National MANPADS Workshop,
