This SAE Aerospace Information Report (AIR) identifies the risks and dangers associated with the carriage and use of pyrotechnic signaling devices in transport category aircraft life rafts and slide/rafts, and provides a rationale for allowing the use of alternative non-pyrotechnic devices authorized by FAA/TSO-C168. These devices offer an equivalent level of safety while eliminating flight safety risks, enhancing survivability of aircraft ditching survivors, reducing costs, eliminating dangerous goods transportation and handling issues, and reducing environmental impact of dangerous goods disposal
These recommendations are to aid the international air transport industry by identifying a standard, minimum amount of safety instructions and procedures that should be provided in the PSIS. Aircraft operators are encouraged to customize the PSIS to their own operations. This document also provides recommendations for: a Passenger safety information briefings and associated materials, b Demonstration emergency equipment, c Ensuring passenger suitability for those seated in exit seats, d The standardization of safety briefings for passengers seated at exits who may be responsible for opening exits on transport aircraft during an emergency, and e A standardized protective brace position to reduce the severity of injury during severe turbulence, rapid deceleration, or a sudden impact. In addition, these recommendations pertain to briefings on aircraft on which the cabin crew would conduct the exit seat briefing, and to briefings on aircraft without cabin crew, on which pilots would
This document is divided into five parts. The first part deals with flotation analysis features and definitions to acquaint the engineer with elements common to the various methods and the meanings of the terms used. The second part identifies and describes current flotation analysis methods. Due to the close relationship between flotation analysis and runway design, methods for the latter are also included in this document. As runway design criteria are occasionally used for flotation evaluation, including some for runways built to now obsolete criteria, a listing of the majority of these criteria constitutes the third part. The fourth part of this document tabulates the most relevant documents, categorizing them for commercial and civil versus military usage, by military service to be satisfied, and by type of pavement. This document concludes with brief elaborations of some concepts for broadening the analyst’s understanding of the subject. At revision B of this document

This document provides an approach for determining which parts on aircraft seats are required to meet the test requirements of 14 CFR Part 25 Appendix F, Parts IV and V. Additionally, it is recommended to use materials that meets the requirements of 14 CFR Part 25 Appendix F, Parts IV and V in applications where not required. Independent furniture installations related to seat installations are outside the scope of this document
This SAE Aerospace Recommended Practice (ARP) provides information and recommended guidelines for handling carry-on baggage prior to emergencies and during the emergency evacuation of transport category aircraft. Recommendations are provided on limiting the size, amount, and weight of carry-on baggage brought into the cabin, improved stowage of carry-on baggage to minimize hazards to passengers in flight and during emergency evacuations, and procedures to ensure carry-on baggage is not removed during an emergency evacuation
This document is divided into five parts. The first part deals with flotation analysis features and definitions to acquaint the engineer with elements common to the various methods and the meanings of the terms used. The second part identifies and describes the various methods used. To accomplish the minimum intent of this document, techniques could be limited to those needed for flotation analysis only; however, because of the close relation between flotation analysis and runway design, methods for the latter are also included. In fact, runway design criteria are used for flotation and evaluation in some cases, and are periodically the governing procedure in specific, if isolated, instances. From time to time, it may be necessary to deal with runways built to obsolete criteria. Therefore, a listing of most of these constitutes the third part. The fourth part of this document tabulates the recommended documents, categorizing them for commercial and civil versus military usage, by

This document discusses the work done by the U.S. Army Corps of Engineers and the Waterways Experiment Station (WES) in support of SAE A-5 Committee activity on Aerospace Landing Gear Systems. It is an example of how seemingly unrelated disciplines can be combined effectively for the eventual benefit of the overall aircraft system, where that system includes the total airfield environment in which the aircraft must operate. In summary, this AIR documents the history of aircraft flotation analysis as it involves WES and the SAE

The main aim of this paper is to optimize pneumatic tyre parameters related that improve tyre flotation and performance on sandy soils. Tyre flotation pressure is the pressure of inflation that makes tyre flotation maximum such that it deforms more than it sinks in the soil. A second aim is to predict the tyre flotation pressure on dry sandy soil by using Artificial Neural Networks (ANNs) Technique. A third aim is to predict a new tyre size that improves flotation on dry sand by using Artificial Neural Networks (ANNs) Technique. Experimental investigation has been carried out on three tubeless tyre of sizes (225/75R15, 235/70R15 and 255/60R15) inflated each with four inflation pressures (50, 100, 150 and 200 kPa) on three dry sand with three densities (Loose, Medium, and High). The investigation aimed at determines the tyre deflection-load, sinkage-load relationships were measured and the tyre flotation pressure. The artificial neural network (in MATLAB program) simulating the tyre
Figure 1 shows a prototype of a large pressure vessel under development for eventual use as a habitable module for long spaceflight (e.g., for transporting humans to Mars). The vessel is a hybrid that comprises an inflatable shell attached to a rigid central structural core. The inflatable shell is, itself, a hybrid that comprises (1) a pressure bladder restrained against expansion by (2) a web of straps made from high-strength polymeric fabrics. On Earth, pressure vessels like this could be used, for example, as portable habitats that could be set up quickly in remote locations, portable hyperbaric chambers for treatment of decompression sickness, or flotation devices for offshore platforms. In addition, some aspects of the design of the fabric straps could be adapted to such other items as lifting straps, parachute straps, and automotive safety belts

These recommendations are to aid the air transport industry in providing standard passenger safety information cards for use on commercial passenger carrying aircraft
In addition to those aspects of a passenger seat such as comfort and appearance, the passenger seat, whether aft, forward, or side-facing is the basic link that supports and ties the air transport passenger to the aircraft structure. It is essential that the support and tiedown functions be accomplished in a manner that will provide maximum safety and security during all normal conditions of flight, emergency flight maneuvers and crash landings, whether on land or sea and that these functions not be compromised to attain the comfort and appearance features
This ARP covers stowage of all portable cabin emergency equipment, such as oxygen bottles/masks, fire extinguishers, first aid kits, megaphones, flashlights, axes, life rafts, survival kits, life preservers, etc. The following criteria are recommended as general provisions in conjunction with the current applicable Federal Aviation Administration requirements
