A v I a t AAIR Passenger Airbag System for Transport Aircraft

Authors:

Dynamic performance requirements for aircraft seats were introduced in 1988, greatly expanding the process of certifying a transport aircraft interior. Compliance to many aspects of Federal Aviation Regulation (FAR) and the Joint Airworthiness Requirement (JAR) 25.562 has become a mature process. Compliance to the head injury requirement, however, persists as a difficult and expensive venture. The most practical means to comply with the HIC requirement, although satisfying the regulation, often do not satisfy the original objective of the rule. AmSafe Aviation developed airbag technology to address both commercial and safety concerns surrounding the head injury issue. This paper first provides a basis to understand the issue by addressing the purpose of 25.562 followed by an explanation of Head Impact Criteria (HIC). The paper then illustrates concerns with the compliance to 25.562, and how the Amsafe Aviation Inflatable Restraint (AAIR) addresses them.

Scope and method of study. The purpose of this experimental study was to examine the effects of applying a single standard of engineering safety (S3E) on the airworthiness of military derivative aircraft. For the purpose of this study, S3E is defined as the use of commercial standards for airworthiness in embodied in Federal Aviation Regulation (FAR) 121 and Federal Aviation Administration (FAA) ... [Show full abstract] Order 8300.10, then tailored and applied to the Department of Defense (DOD). Using a S3E audit normally used to inspect airlines but specially tailored to the military two randomly selected military units were pre-tested. Although the random selection was blind to the study it is known that the units were of different services but operated the same type of commercially built and certified military derivative aircraft. It is also known that their force of strength and fleet size were the same. After the pre-test, one unit was treated by exposure to S3E commercial standards for airworthiness per FAR Part 121 and FAA Order 8300.10 and the other unit was not. After 90 days, both units were post-tested. Percent change comparison on the pre and post test as well as the chi squared technique was used to analyze the data. Findings and conclusions. The results of the study indicate that the treated unit experienced significant improvement in airworthiness compliance and the control unit did not. It was concluded that S3E had a positive effect in this first of its kind study, but further and expanded research needs to continue.

Effect of conductivity between fasteners and aluminum skin on eddy current specimens

January 1970

The Federal Aviation Administration Airworthiness Assurance Nondestructive Inspection Validation Center (FAA-AANC) and Boeing Commercial Airplane Group are currently developing a study pertaining to the detection of cracks in multi-layered aluminum sheets. The specimen panels model pertinent aspects of the lap splice joints for Boeing 737 aircraft, Line Numbers 292 - 2565. Upon initial ... [Show full abstract] characterization of the specimen panels, it became clear that signals produced from a sliding probe at fastener sites were not representative of an in-service lap splice, and therefore, could not be used in a probability of detection experiment. This paper discusses specimen characterization and steps taken to make the specimens useful for nondestructive technology assessment.

Icing Certification of Civil Aircraft Engines

December 2011 · Procedia Engineering

Aeroengine icing is an unwanted phenomenon which can normally lead to the hazardous effect to the power of aircraft during routine flight. To be on the safe side, each civil aircraft engine model must fully meet the strict requirements of icing operation and ice ingestion in the authoritative certification program, and usually this could be demonstrated by using the experimental approach. Base on ... [Show full abstract] a concrete engine model, this paper aims to provide an acceptable method of compliance to the engine icing operation and ice ingestion requirements which are demanded by the US airworthiness standards of aircraft engines, i.e., Federal Aviation Administration 14 CFR Part 33, and introduce the application of critical point analysis and experimental arrangement in engine icing certification. Through the textual description, it would be greatly helpful to the industrial community to evaluate the engine anti-icing capability and conduct the ice-slab ingestion demonstration in engine design process.

This chapter discusses safety engineering carried out during the different phases of the development of a type of systems. Safety is a state in which the risk is acceptable, whereas the term “risk” corresponds to the probability of occurrence of an event associated with its severity. ARP4754A recommendation defines the safety assessment as the process which, carried out jointly with other ... [Show full abstract] ARP4754A processes, enables to ensure the compliance of an aircraft system with airworthiness requirements such as the 1309 requirement of the US Federal Aviation Regulations (FARs) or the EASA Certification Specifications (CSs). The chapter discusses the concepts of failure, fault and error. These concepts are introduced in connection to those of function, behavior and structure of the Function-Behavior-Structure (FBS) framework. It shows that the derivation of safety requirements (quantitative or qualitative) with respect to a given design architecture amounts to leading a preliminary safety assessment (PASA/PSSA).

Designing for reuse: a case study

June 1992 · ACM SIGAda Ada Letters

David M. Wade

After considerable analysis of the many problems associated with software reuse, and a critical review of the benefits to be gained, the Federal Aviation Administration (FAA) Advanced Automation System (AAS) decided to proceed with a strong, unified reuse effort across the project. In June 1989 a Reuse Working Group (RWG) was formed. This group defined project wide reuse procedures and oversaw ... [Show full abstract] their compliance. Initial feedback from the effort has been encouraging, but there are many obstacles yet to overcome. This paper provides some insight into the AAS reuse process by following the progress of a key reusable software component. It also highlights the side benefits the project garnered as the component's design solidified. The component being examined is the Airspace Volumes Subsystem, which defines an abstraction of an Airspace Volume and provides operations which control interactions between Airspace Volumes and other airspace objects, such as aircraft.

How is Configuration Management in Aircraft Industry implemented?

June 2009

RESUMEN Apenas existe literatura sobre el empleo de Gestión de Configuración (CM) en la Industria Aeronáutica. Sin embargo, puede resultar muy útil en el momento actual, en que la complejidad para hacer aviones es creciente y la aplicación de CM resulta muy apropiada. Las piezas de la aeronave se fabrican en diferentes países, incluso se montan las mismas piezas en países y factorías distintas. ... [Show full abstract] Los diseños con materiales diversos y cada vez más ligeros, no hacen sino incrementar la complejidad, y además se une que los clientes solicitan versiones diferentes del mismo modelo, que son cambiantes con el transcurso de los años. Los objetivos más importantes de la CM son: garantizar que existe conformidad entre productos y servicios que se han entregado al cliente, ABSTRACT There is little literature on the use of Configuration Management (CM) in the Aviation Industry. However, it can be very useful today, where complexity to manufacture aircraft is increasing, and application of CM is very suitable. The pieces of the aircraft are produced in different countries, even the same parts are assembled in different countries and factories. Designs with different materials, and products increasingly lightweight, enhanced the complexity. In addition customers request very different versions of the same model, which are changing over years. The two most important objectives of the CM are to guarantee that there is compliance between the products and services that have been delivered to the customer, and to support the process of application for individual certificate of airworthiness, while optimized business performances are taken into account. The main objective of the study is how the CM is implemented in the aviation industry with an immediate applicability. CM is a discipline that arises from the need to ensure control in the complex process of relationships. CM is well suited to solving complex problems, like in aircraft industry. Its application allows the reduction of periods of integration and design, so that reduce delivery time to customers.
