Abstract: In some examples, a computing device is configured to monitor an air quality of a vehicle cabin by at least receiving, from a plurality of remote sensors distributed throughout the cabin, signals indicative of one or more air quality parameters for air in the cabin. Based on the received signals, the computing device can determine if values for the one or more air quality parameters are indicative of an air quality event and generate an output in response to such a determination. The output may include, for example, an audio or visual indication of the air quality event or a signal to control another system of the aircraft to take action to remedy the air quality event.

Abstract: An electrical distribution control system for a vehicle such as an aircraft may be provided fire-suppression protection without requiring that all control elements are located in a fire-containment enclosure. A primary electric load center (ECL) may be located in a fire-containment equipment bay. Secondary power control centers (SPC's) may be located away from the equipment bay and close to set of loads which are controlled by the SPC's. Each SPC may be provided with a fire detecting sensor that may signal the ECL to interrupt input power to the SPC in the event of a fire in the SPC. The SPC may be constructed from self-extinguishing material. In an absence of input power to the SPC, a fire may self extinguish, thus preventing flame propagation or production of excessive external heat.
