Abstract: An evacuation guidance system may comprise a plurality of floor guidance lights, a plurality of seat guidance lights, a plurality of exit signs, and a controller in communication with the plurality of floor guidance lights, the plurality of seat guidance lights, and the plurality of exit signs. The plurality of floor guidance lights may include a plurality of fore-aft floor lights and a plurality of port-starboard floor lights. The controller may be configured to determine a closest exit door to each floor guidance light, each seat guidance light, and each exit sign. The controller may command each floor guidance light, each seat guidance light, and each exit sign to indicate a direction of the closest exit door.

Abstract: An evacuation slide light system may comprise a sensor, a controller configured to receive a signal from the sensor, and a projector light operably coupled to the controller. The sensor may be configured to measure at least one of a pressure of the evacuation slide or a stretch of a material of the evacuation slide. The controller may determine the pressure of the evacuation slide based on the signal from the sensor. The controller may be configured to command the projector light to emit a first image if the pressure of the evacuation slide is less than a threshold pressure and to emit a second image if the pressure of the evacuation slide is greater than or equal to the threshold pressure.

Abstract: A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.
