Abstract: A visual assurance apparatus for an aircraft includes an inflatable enclosure which is in a normally uninflated state. When inflated, the inflatable enclosure defines a visual path between the pilot and the windshield and between the pilot and the instrument panel. Thus, the pilot can see even when dense smoke is present in the cockpit.
Abstract translation: 用于飞行器的视觉保证装置包括处于正常未充气状态的可充气外壳。 当充气时，可充气外壳限定了飞行员和挡风玻璃之间以及飞行员和仪表板之间的视觉路径。 因此，即使驾驶舱中存在密集的烟雾，飞行员也可以看到。

Abstract: A smoke hood is provided which is highly compact, quickly assembled, and light-weight. The device is defined by a tubular, transparent portion made from KAPTON, having a closed upper end and a lower skirt portion adapted to fit over at least the head of a user. A neck seal is attached to the interior of the tube and is designed to allow the user to quickly put on the hood without allowing any of the outside environment to flow into the hood. Inflow and outflow valves are attached to the hood the former of which connects to an air supply system. A method for assembling the hood is also provided along with details of an inflow valve arrangement, an outflow valve arrangement, and a kink-free air supply hose structure.

Abstract: A life support system is provided for users located within enclosed areas to supply them with fresh air from a location exterior of the enclosed area, and is particularly adapted for use in emergency circumstances such as when fire and smoke fill enclosed areas. The system can be used in buildings and in aircraft and can be adapted for use with the gasper outlets presently employed on aircraft. A method for providing fresh exterior air to the enclosed area and the user includes conducting the air to an outlet for the exterior air which is located within the area, conducting the exterior air from the outlet to at least one breathing cavity of the user, and preventing the user from inhaling ambient atmosphere from within the enclosed area.

Abstract: An emergency visual assurance apparatus for an aircraft cockpit comprises an inflatable enclosure having inflated and deflated states. The enclosure is adapted to fill the visual path between a pilot and an instrument panel and/or a windshield of an aircraft when in the inflated state. The inflatable enclosure includes windows for permitting the pilot to see through the enclosure, thereby enabling the pilot a clear path of visibility to the instrument panel and/or the windshield during a smoke emergency in the cockpit. A blower is provided for inflating the inflatable enclosure with transparent fluid during an emergency to maintain the visual path between the pilot and the instrument panel and/or the windshield. A separable member is associated with the blower such its removal activates the blower.
