This document provides guidance for in-flight rest facilities provided for use by cabin crew on commercial transport airplane. This document is applicable to dedicated cabin crew rest facilities with rigid walls. The facility includes a bunk or other surface that allows for a flat sleeping position, is located in an area that is temperature-controlled, allows the crew member to control light, and provides isolation from noise and disturbance
A new device known as MC-TENG — short for multilayered cylindrical triboelectric nanogenerator — generates electrical power by harvesting energy from the sporadic movement of the tree branches from which it hangs. The self-powered sensing system could continuously monitor the fire and environmental conditions without requiring maintenance after deployment
This SAE Aerospace Standard (AS) specifies the minimum design and performance criteria and testing methods of fire containment covers (FCCs) used either: a In those cargo compartments of civil transport aircraft where they constitute one means of complying with applicable airworthiness regulations, or b On a voluntary basis, when deemed appropriate by operators to improve fire protection in aircraft cargo compartments where airworthiness regulations do not mandate their use
Solar or photovoltaic (PV) cells fixed to roofs convert sunlight into electricity. Bringing that technology indoors could further boost the energy efficiency of buildings and energize swaths of wireless smart technologies such as smoke alarms, cameras, and temperature sensors

This ARP addresses the issue of passengers smoking in aircraft lavatories and the need to improve warnings about the danger of fire caused by smoking
Wildfires that start in backcountry areas sometimes burn for hours before being detected and reported. Satellites offer a vantage point from which infrared sensors can detect fires. Individual satellites in low Earth orbit (LEO) offer infrequent overpasses, making the delay from ignition to detection unacceptably long. Geostationary satellites offer a platform from which to maintain a round-the-clock vigil, but lack geographic precision, and cannot detect a rather small fire within a large pixel definitively above noise
The National Aeronautics and Space Administration (NASA) uses large quantities of liquid hydrogen and has expended significant effort in the development, testing, installation, and maintenance of hydrogen fire detectors based on ultraviolet, near-infrared, mid-infrared, and/or far-infrared flame emission bands. Yet, prior to this work, there was no intensity-calibrated broadband hydrogen-air flame spectrum in the literature, making it difficult to compare the merits of different radiation-based hydrogen fire detectors
This SAE Aerospace Standard (AS) specifies minimum performance standards for the following types of fire detection instruments intended for use in protecting aircraft cargo compartments, galleys, electronic equipment bays and other similar installations
Traditional smoke opacity measurement, performed on diesel engines during regular emissions inspections, sensitive primarily to larger particles of elemental carbon, is very little sensitive to nanoparticles and to semi-volatile “organic carbon” particles. For this reason, it no longer suffices as a high emitter detection tool for modern vehicles with a particle filter or for advanced low-emissions technology where semi-volatile organic particles are the dominant fraction of particulate matter. This paper investigates the potential of common low-cost ionization type smoke detectors, produced in mass quantities for fire detection in buildings, as a tool to measure particle emissions in vehicular exhaust. Two ionization chambers were used to measure both raw and diluted exhaust of various engines powered by diesel fuel and biofuels under laboratory conditions as well as on the road. Laboratory results suggest that the ionization chamber signal correlates best to total particle length
This SAE Aerospace Standard (AS), identical to ISO 14186, specifies the minimum design and performance criteria and testing methods of fire containment covers (FCCs) used either: a in those cargo compartments of civil transport aircraft where they constitute one means of complying with applicable airworthiness regulations, or b on a voluntary basis, when deemed appropriate by operators to improve fire protection in aircraft cargo compartments where airworthiness regulations do not mandate their use
A document discusses an optical carbon monoxide sensor for early fire detection. During the sensor development, a concept was implemented to allow reliable carbon monoxide detection in the presence of interfering absorption signals
Distinctly different fire hazards exist within the engine compartment of a transit vehicle and various detection methodologies may be employed to detect fire events arising from these hazards. The engine compartment presents a particularly challenging environment and it is important to select the correct methodology to ensure timely detection response in the early stages of the development of a fire whilst minimizing nuisance alarms. The choice of the correct detection methodology for a specific fire hazard is therefore determined by the suitability of the methodology for the detection of the anticipated fire event within the environment in which it is required to operate. This paper presents experimental data to demonstrate the variation in the response times of different detection methodologies in the presence of common fire events in the form of simulated flaming fuel fires and a simulated electrical fault in the form of an overheated electrical cable. The data presented relates to

This document establishes requirements, test procedures, and acceptance criteria for the fire testing of fluid handling components and materials used in aircraft fluid systems. It is applicable to fluid handling components other than those prescribed by AS1055 (e.g., hoses, tube assemblies, coils, and fittings). It also is applicable to materials, wiring, and components such as reservoirs, valves, gearboxes, pumps, filter assemblies, accumulators, fluid-cooled electrical/electronic components, in-flight fluid system instrumentation, hydromechanical controls, actuators, heat exchangers, and manifolds. These components may be used in fuel, lubrication, hydraulic, or pneumatic systems
This SAE Recommended Practice applies to Liquefied Natural Gas Vehicle Fuel. The purpose of this document is to provide information on issues that are important to consider regarding LNG metering and dispensing systems
