Abstract
A cargo-fire-suppression agent distribution system and methods are presented. A fire-warning signal indicating presence of fire in a cargo compartment onboard a class E cargo aircraft at a first altitude is received. An initial fire-suppression agent is distributed in the cargo compartment at the first altitude sufficient to suppress fire for an initial fire suppression time interval during a depressurization phase during which the class E cargo aircraft flies to a second altitude below the first altitude. A re-enforcing fire-suppression agent is distributed in the cargo compartment during a re-pressurization phase when a cabin altitude is below a predetermined cabin pressure level (PL) during which the class E cargo aircraft flies from the second altitude to a landing, after the initial fire-suppression time interval elapses. The re-enforcing fire-suppression agent distribution is maintained during a re-enforcing fire-suppression time interval.
