    Full Text Available Aviation as a mode of transportation requires that the aircraft designed, developed, andoperated must be maintained under airworthy condition. The basic tenet of airworthiness is thatthe aircraft designed and developed are certified by the independent airworthiness regulatoryorganisations. This requires strict vigil during the development stages. With quantum jump inthe design and development activities, it has been extremely difficult for the regulatory bodiesto cope up with the demand of certification. Delegating this responsibility to a few approvedfirms prove very effective in maintaining the design control through approved agencies andpersonnel. Airworthiness approval of design firms taken up by the Centre for MilitaryAirworthiness & Certification, Bangalore, which is the airworthiness approval authority for militaryaircraft in India, is one such step. This paper discusses the scope and extent of such approvals.

  1. Airworthiness verification of an airborne telescope in practice

    Science.gov (United States)

    Dreger, Hartmut; Bremers, Eckhard; Kuehn, Juergen; Eisentraeger, Peter

    2003-02-01

    The SOFIA Telescope is part of the outer hull of the pressurized passenger cabin of the SOFIA aircraft, in which the aircraft crew, the astronomers and their guests are located during flight. Therefore the telescope - including the science instrument - is an airworthiness relevant component of the observatory and has to fulfill airworthiness standards ac-cording the Federal Aviation Authority. The airworthiness issues were main drivers in the process of design, manufacturing, quality control, testing and documentation. The paper describes the experience gotten during this troublesome, exciting and costly job.

    Science.gov (United States)

    Stapleford, R. L.; Heffley, R. K.; Rumold, R. C.; Hynes, C. S.; Scott, B. C.

    1974-01-01

    A simulator study of short takeoff and landing (STOL) aircraft was conducted using a model of a deflected slipstream transport aircraft. The subjects considered are: (1) the approach, (2) flare and landing, (3) go-around, and (4) takeoff phases of flight. The results are summarized and possible implications with regard to airworthiness criteria are discussed. A data base is provided for future STOL airworthiness requirements and a preliminary indication of potential problem areas is developed. Comparison of the simulation results with various proposed STOL criteria indicates significant deficiencies in many of these criteria.

    Maddalon, Jeffrey M.; Hayhurst, Kelly J.; Koppen, Daniel M.; Upchurch, Jason M.; Morris, A. Terry; Verstynen, Harry A.

    2013-01-01

    The use of unmanned aircraft in the National Airspace System (NAS) has been characterized as the next great step forward in the evolution of civil aviation. Although use of unmanned aircraft systems (UAS) in military and public service operations is proliferating, civil use of UAS remains limited in the United States today. This report focuses on one particular regulatory challenge: classifying UAS to assign airworthiness standards. This paper provides observations related to how the current regulations for classifying manned aircraft could apply to UAS.

    2012-01-01

    A study is conducted on a new airworthiness compliance verification method based on pilot-aircraft-environment complex system simulation.Verification scenarios are established by “block diagram” method based on airworthiness criteria..A pilot-aircraft-environment complex model is set up and a virtual flight testing method based on connection of MATLAB/Simulink and Flightgear is proposed.Special researches are conducted on the modeling of pilot manipulation stochastic parameters and manipulation in critical situation.Unfavorable flight factors of certain scenario are analyzed,and reliability modeling of important system is researched.A distribution function of small probability event and the theory on risk probability measurement are studied.Nonlinear function is used to depict the relationship between the cumulative probability and the extremum of the critical parameter.A synthetic evaluation model is set up,modified genetic algorithm (MGA) is applied to ascertaining the distribution parameter in the model,and amore reasonable result is obtained.A clause about vehicle control functions (VCFs) verification in MIL-HDBK-516B is selected as an example to validate the practicability of the method.

  19. Digital virtual flight testing and evaluation method for flight characteristics airworthiness compliance of civil aircraft based on HQRM

    Institute of Scientific and Technical Information of China (English)

    Liu Fan; Wang Lixin; Tan Xiangsheng

    2015-01-01

    In order to incorporate airworthiness requirements for flight characteristics into the entire development cycle of electronic flight control system (EFCS) equipped civil aircraft, digital virtual flight testing and evaluation method based on handling qualities rating method (HQRM) is proposed. First, according to HQRM, flight characteristics airworthiness requirements of civil aircraft in EFCS failure states are determined. On this basis, digital virtual flight testing model, comprising flight task digitized model, pilot controlling model, aircraft motion and atmospheric tur-bulence model, is used to simulate the realistic process of a pilot controlling an airplane to perform assigned flight tasks. According to the simulation results, flight characteristics airworthiness com-pliance of the airplane can be evaluated relying on the relevant regulations for handling qualities (HQ) rating. Finally, this method is applied to a type of passenger airplane in a typical EFCS failure state, and preliminary conclusions concerning airworthiness compliance are derived quickly. The research results of this manuscript can provide important theoretical reference for EFCS design and actual airworthiness compliance verification of civil aircraft.

  15. Ground-simulation investigation of VTOL instrument flight rules airworthiness criteria

    Science.gov (United States)

    Lebacqz, J. V.; Scott, B. C.

    1984-01-01

    A two-part ground-simulation investigation of VTOL terminal-area operations, conducted as part of a joint NASA/FAA program to develop airworthiness criteria for this class of vehicle, is described. The baseline vehicle selected for the simulations was a generalized version of the XV-15 tilt-rotor mathematical model, which was modified to permit generic variations in forces or moments or both with power or configuration changes. Additionally, changes to wing area and rotor-blade chord were considered as a means of modifying the allowable thrust-angle versus speed relationships (the conversion corridor). The Vertical Motion Simulator at Ames Research Center was used in the experiment. Four engineering test pilots conducted over 200 piloted evaluations examining the influence of the experimental variables on their ability to perform terminal-area operations.

    1990-01-01

    Several ground-based simulation experiments undertaken to investigate concerns related to tilt-rotor aircraft airworthiness were conducted. The experiments were conducted on the National Aeronautics and Space Administration (NASA) Ames Research Center's Vertical Motion Simulator, which permits simulation of a wide variety of aircraft with a high degree of fidelity of motion cueing. Variations in conversion/deceleration profile, type of augmentation or automation, level of display assistance, and meteorological conditions were considered in the course of the experiments. Certification pilots from the Federal Aviation Administration (FAA) and the Civil Aviation Authority (CAA) participated, in addition to NASA research pilots. The setup of these experiments on the simulator is summarized, and some of the results highlighted.

  17. Federal Aviation Administration (FAA airworthiness certification for ceramic matrix composite components in civil aircraft systems

    Directory of Open Access Journals (Sweden)

    Gonczy Stephen T.

    2015-01-01

    Full Text Available Ceramic matrix composites (CMCs are being designed and developed for engine and exhaust components in commercial aviation, because they offer higher temperature capabilities, weight savings, and improved durability compared to metals. The United States Federal Aviation Administration (FAA issues and enforces regulations and minimum standards covering the safe manufacture, operation, and maintenance of civil aircraft. As new materials, these ceramic composite components will have to meet the certification regulations of the FAA for “airworthiness”. The FAA certification process is defined in the Federal Aviation Regulations (Title 14 of the Code of Federal Regulations, FAA policy statements, orders, advisory circulars, technical standard orders, and FAA airworthiness directives. These regulations and documents provide the fundamental requirements and guidelines for design, testing, manufacture, quality assurance, registration, operation, inspection, maintenance, and repair of aircraft systems and parts. For metallic parts in aircraft, the FAA certification and compliance process is well-established for type and airworthiness certification, using ASTM and SAE standards, the MMPDS data handbook, and FAA advisory circulars. In a similar manner for polymer matrix composites (PMC, the PMC industry and the FAA have jointly developed and are refining parallel guidelines for polymer matrix composites (PMCs, using guidance in FAA circulars and the CMH-17 PMC handbook. These documents discuss design methods and codes, material testing, property data development, life/durability assessment, production processes, QA procedures, inspection methods, operational limits, and repairs for PMCs. For ceramic composites, the FAA and the CMC and aerospace community are working together (primarily through the CMH-17 CMC handbook to define and codify key design, production, and regulatory issues that have to be addressed in the certification of CMC components in

  16. 噪声适航标准严格化趋势探究%Study on Stringency of Noise Airworthiness Standards

    Institute of Scientific and Technical Information of China (English)

    2013-01-01

    The International Civil Aviation Organization (ICAO) recommended a standard for the aircraft noise. In Appendix 16 Volume I of the International Aviation Law“Aircraft Noise”, the aircrafts are divided into four classes according to their noise level, illustrated respectively in chapters 1-4 in ICAR-36. According to the law, the aircrafts must pass the noise check-up before obtaining the qualified airworthiness certification. Now, the ICAO is preparing more serious noise standard. It is predicted that in 2016 the limitation of the airworthiness noise of giant passenger airplane will be lowed by 18EPN dB in comparison with the noise standard of the fourth class of the aircrafts. In order that the design and manufacture of the civil aviation aircrafts satisfy the international noise standard, the renewing of the noise check-up standard should be studied.%  国际民航组织制定了航空器噪声审定的建议标准—国际民航公约附件16第I卷“航空器噪声”,把航空器按噪声水平分成第一、二、三、四章标准的飞机(即CCAR-36中的第一、二、三、四阶段飞机),要求飞机在投入运营之前,必须进行并通过飞机噪声适航合格审定,否则不予颁发适航合格证。同时,国际民航组织正在研究更严格的噪声标准。预计到2016年,大型客机适航噪声将比第四阶段噪声限制低18 EPN dB以上。为使中国民用航空器的设计制造满足国际通行的噪声标准,需研究更新后的噪声审定标准。
