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.

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).

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.

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
