chapter 6 the Type Certification process
Airworthiness (Third Edition)#R##N#An Introduction to Aircraft Certification and Operations, 2016Co-Authors: Filippo De FlorioAbstract:In this chapter we describe the European Aviation Safety Agency (EASA) and Federal Aviation Administration (FAA) Type Certification processes pointing out the substantial differences between them from an organisational point of view. Of course, the final result is the same: endorse the compliance of the Type design to the applicable Certification basis by issuing a Type certificate. We will quote a list of related and key advisory material, also depicting ideas on the construction of protoTypes and test articles. Although the basic philosophical concepts of Type Certification procedures are generally the same for the EASA, and FAA, there are some peculiarities in the Type Certification process that necessitate an individual description of the two processes.

chapter 5 Type Certification
Airworthiness (Third Edition)#R##N#An Introduction to Aircraft Certification and Operations, 2016Co-Authors: Filippo De FlorioAbstract:This chapter deals with the Type Certification of aircraft, engines, and propellers. Federal Aviation Regulations 21 and European Aviation Safety Agency (EASA) Part 21 establish the requirements for issuing a Type certificates, document by which the authority states that an applicant has demonstrated compliance of a Type design to all applicable requirements. Federal Aviation Administration and EASA have different kinds of Type certificates that are only listed here because detailed information is provided in Chapter 8 of this book. Connected with the Type Certification are the requirements for changes to Type certificates, the approval of parts and appliances, the environmental protection and the Certification of imported product. A subchapter is dedicated to the EASA Design Organisation Approval.

The Type Certification Process
Airworthiness, 2011Co-Authors: Filippo De FlorioAbstract:This chapter discusses the Type Certification process. The national authorities proposed some specialists for each Certification; these specialists were evaluated on the basis of their experience (a curriculum vitae was required), and then the JAA assessed and approved the composition of the team. A Program Manager, with the main task of coordinating the team's work, was appointed in a similar way. JAA local procedure Type Certification of products of the “lower” range, such as very light aeroplanes, sailplanes, and powered sailplanes, some JAR 23 single-engine aeroplanes, and so on. Type Certification of this kind of product involved, in general, a smaller team and less-complex management. Therefore, the Certification process was assigned to a national authority (possibly to the applicant's national authority), which had to be acknowledged by the JAA as the Primary Certification Authority (PCA).

chapter 5 Type Certification
Airworthiness (Second Edition)#R##N#An Introduction to Aircraft Certification, 2011Co-Authors: Filippo De FlorioAbstract:Publisher Summary This chapter discusses the Type Certification. The Type certificate is a document by which the authority states that an applicant has demonstrated the compliance of a Type design to all applicable requirements. This certificate is not in itself an authorization for the operation of an aircraft, which must be given by an airworthiness certificate. The Type design “freezes” not only the product configuration but also the production methods. Every deviation from the Type design becomes a “change” which must be approved, as we will see. This is to make sure that the series products are not inferior to the protoType identified by the Type design, in terms of flight safety. EASA Part 21 and FAR 21, for Type Certification, include the designation of applicable environmental protection requirements and Certification specifications, missing in JAR 21.

airworthiness an introduction to aircraft Certification
2006Co-Authors: Filippo De FlorioAbstract:Understanding airworthiness is central to maintaining and operating aircraft safely. While no book can replace the published Federal Aviation Regulation and Joint Aviation Requirements documentation for airworthiness, this unique guide provides readers with a single reference to understanding and interpreting the airworthiness requirements of the International Civil Aviation Organisation, the US Federal Aviation Administration and the European Aviation Safety Agency (EASA). Key topics covered include: considerations of airworthiness standards for all classes, including large and small aircraft, rotor craft, gliders and unmanned aircraft; Type Certification of aircraft, engines, and propellers and the Type Certification process; parts and appliances approval; and joint Certifications and national Certifications. New to this edition is coverage of Certification for unmanned aircraft systems (UAS); new EASA standards procedures and documentation; and 'spaceworthiness' with relation to recent developments in commercial space travel.

A Model-Based Aircraft Certification Framework for Normal Category Airplanes
'American Institute of Aeronautics and Astronautics (AIAA)', 2020Co-Authors: Bendarkar Mayank, Xie Jiacheng, Briceno Simon, Harrison, Evan D., Mavris, Dimitri N.Abstract:Presented at AIAA Aviation 2020 ForumA typical aircraft Certification process consists of obtaining a Type, production, airworthiness, and continued airworthiness certificate. During this process, a Type Certification plan is created that includes the intended regulatory operating environment, the proposed Certification basis, means of compliance, and a list of documentation to show compliance. This paper extends previous work to demonstrate a model-based framework for the management of these Certification artifacts for normal category airplanes. The developed framework integrates the regulatory rules and approved means of compliance in a single model while using best-practices found in Model-Based Systems Engineering (MBSE) literature. This framework, developed using SysML in MagicDraw captures not just the textual requirements and verification artifacts, but also their relationships and any inherent meta-data properties via custom defined stereoType profiles. Additionally, a simulation capability that automates the extraction and export of the applicable rules (Certification basis) and corresponding means of compliance for any aircraft under consideration at the click of a button has been developed. The framework also provides numerous additional benefits to different stakeholders that have been described in detail with examples where necessary

Differential Dynamic Programming to Critical-Engine-Inoperative Takeoff Certification Analysis
'American Institute of Aeronautics and Astronautics (AIAA)', 2020Co-Authors: Xie Jiacheng, Harrison, Evan D., Mavris, Dimitri N.Abstract:Presented at 2020 AIAA AVIATION ForumCritical-engine-inoperative (CEI) takeoff is a required flight test in transport aircraft Type Certification. Due to the limited excess power following engine failure, this flight test is potentially dangerous and highly sensitive to the flight controls. To enhance the flight safety in CEI takeoff, an optimal longitudinal control sequence is necessary for the flight test. On the other hand, to reduce the cost associated with Type Certification process, it is desired to incorporate Certification analysis in early design phases. Since the Certification regulations pose requirements on aircraft dynamic responses, the point-mass based method used in most of the takeoff analyses for aircraft early design is not suitable. To incorporate flight dynamics in takeoff analysis, a robust longitudinal control law is needed for takeoff performance prediction. This paper proposes to use Differential Dynamic Programming (DDP) for the optimization of elevator control for CEI takeoff Certification analysis. To evaluate the method, two test cases are performed on the CEI takeoff of a small single-aisle aircraft model with different initial conditions. The results of two cases suggests that the DDP algorithm is able to optimize the trajectory in terms of minimizing takeoff distance, maximizing the rate of climb, and improving the compliance with respect to takeoff Certification constraints. The optimized trajectory is sensitive to the initial control sequence given to the algorithm and the cost function settings

Application of the design structure matrix in the safety assessment process used in commercial aircraft design
2017Co-Authors: Marcos Sampaio MartinsAbstract:Resumo: No desenvolvimento e na integração dos sistemas de uma aeronave comercial, o fator segurança em projeto (Design for Safety) é considerado de fundamental importância, uma vez que a certificação do produto pelas autoridades internacionais de aviação civil exige o cumprimento de regulamentações que atestam que um determinado produto (aeronave, componente ou sistema) possui as características mínimas que assegurem seu uso seguro para o tipo de operação pretendida. O processo de projeto que permite a consecução de tais objetivos é conhecido como Safety Assessment, que envolve a aplicação de técnicas de análise de risco desde as fases iniciais de projeto até a certificação de tipo do produto. Este processo, devido a sua complexidade, apresenta interdependência entre atividades (ciclo de iteração) e este cenário representa uma barreira para a redução do tempo de ciclo de projeto. Para endereçar esta questão, é proposto um método que tem como foco a aplicação da matriz de estrutura de projetos (Design Structure Matrix), que é uma técnica de programação de projeto cujo objetivo é o de otimizar o sequenciamento das atividades do processo através do mapeamento do fluxo de informações e da identificação dos ciclos de iteraçãoAbstract: In the commercial aircraft systems development & integration, the safety factor in design (Design for Safety) is considered of fundamental importance since the Certification of the product by the international civil aviation authorities requires compliance with regulations that prove that a product (aircraft, component or system) has the minimum requirements to ensure its safe use for the Type of intended operation. The design process that allows such purposes is known as "Safety Assessment", which involves the application of hazard analysis techniques since the initial stages of design until the product Type Certification. This process, due to its complexity, has interdependence between activities (iteration cycles) and this scenario represents a barrier to reducing cycle time on projects. In order to address this issue, a method is proposed focusing on the application of the "Design Structure Matrix", wich is a project management tool whose objective is to optimize activities sequencing through the mapping flow of information and identify the cycles of iteration in the proces
