A method implemented on an aircraft for controlling a fire suppression system comprises receiving, by a computing system of the aircraft, an indication that the fire suppression system of the aircraft should transition to an active state. The computing system determines whether the aircraft is on a surface. Responsive to determining that the aircraft is on the surface, the computing system controls the fire suppression system to remain or transition to an inactive state.

System and method for controlling a fire suppression system of an aircraft

A fire suppression system for an aircraft having a compartment, the fire suppression system including an inert gas source in selective fluid communication with the compartment and a fire suppression agent source in selective fluid communication with the compartment, wherein an inert gas from the inert gas source and a fire suppression agent from the fire suppression agent source are at least partially combined to form a fire suppression mixture.

Aircraft fire suppression system and method

A smoke detector that is insensitive to moisture, such as for use in aircraft cargo bays and the like, is provided. The smoke detector includes a housing defining a chamber that is sealed from outside light sources yet is capable of receiving smoke. The smoke detector also includes a light source that is positioned inside the chamber and a detector for receiving diffusely scattered light within the chamber. Advantageously, the smoke detector also includes a moisture compensating device that reflects a substantially consistent percentage of light incident thereupon regardless of moisture on the surfaces thereof such that the operation of the light source can be reliably tested even in environments where moisture has condensed or otherwise collected on the walls of the housing.
