  • OPTIONS FOR AIRPORT APPROACH NOISE CONTROL: FLIGHT PROCEDURES, Aircraft Certification, AND AIRPORT RESTRICTIONS
    Transportation Research Record, 1999
    Co-Authors: Robert E. Caves, A D Kershaw, D P Rhodes
    Abstract:

    The use of larger Aircraft and high-bypass engines has made the approach noise at airports more critical, but the methods used to control it rely on rather tenuous relationships between Aircraft noise Certification and the noise experienced by the communities around airports. Also, the options for alleviating approach noise are perceived to be fewer than for the takeoff case. The effect of a variety of possible approach flight procedures is explored. All of these procedures terminate in a conventional 3-degree final glide path, on the maximum noise levels under the flight path. In comparison, the effect of varying the glideslope angle on noise at the approach Certification point is reported. It is concluded that the most promising procedures for alleviating noise in the areas some distance from an airport are the Continuous Descent and the Decelerating approaches. The current use of these techniques is limited by the incompatibility with air traftraffic control procedures. The more severe noise levels closer …

  • Characterization of Aircraft Icing Environments with Supercooled Large Drops for Application to Commercial Aircraft Certification
    Journal of Applied Meteorology and Climatology, 2012
    Co-Authors: Stewart G. Cober, George A. Isaac
    Abstract:

    AbstractObservations of Aircraft icing environments that included supercooled large drops (SLD) greater than 100 μm in diameter have been analyzed. The observations were collected by instrumented research Aircraft from 134 flights during six field programs in three different geographic regions of North America. The research Aircraft were specifically instrumented to accurately measure the microphysics characteristics of SLD conditions. In total 2444 SLD icing environments were observed at 3-km resolution. Each observation had an average liquid water content (LWC) > 0.005 g m−3, drops > 100 μm in diameter, ice crystal concentrations 500 μm in diameter, each with median drop volume diameters 40 μm. For each SLD subset, the observations were used to develop envelop…

  • Community response to low-amplitude sonic booms
    Journal of the Acoustical Society of America, 2013
    Co-Authors: Alexandra Loubeau
    Abstract:

    Sonic boom research conducted at NASA is oriented toward understanding the potential impact of sonic boom noise on communities from new low-boom supersonic Aircraft designs. This research contributes to knowledge in key areas needed to support development of a new noise-based standard for supersonic Aircraft Certification. Partnerships with several industry, government, and academic institutions have enabled the execution of a pilot low boom community response test to develop and assess experimental methodologies, including sonic boom data acquisition, subjective data collection, and data analysis. Areas of additional research are identified and a prioritization of issues is performed to guide design of a potential follow-on pilot test. Lessons learned from these community response tests will facilitate future community testing with actual low-boom Aircraft in communities not familiar with sonic booms.

  • Recent Progress on Sonic Boom Research at NASA
    , 2012
    Co-Authors: Alexandra Loubeau
    Abstract:

    Sonic boom research conducted at NASA through the Supersonics Project of the Fundamental Aeronautics Program is oriented toward understanding the potential impact of sonic boom noise on communities from new low-boom supersonic Aircraft designs. Encompassing research in atmospheric propagation, structural response, and human response, NASA research contributes to knowledge in key areas needed to support development of a new noise-based standard for supersonic Aircraft Certification. Partnerships with several industry, government, and academic institutions have enabled the recent execution of several acoustic field studies on sonic booms. An overview of recent activities funded by NASA includes: focus boom model development and experimental validation, field experiments of structural transmission of sonic booms into large buildings, and low boom community response testing.

  • Chapter 4 – Airworthiness Requirements
    Airworthiness, 2011
    Co-Authors: Filippo De Florio
    Abstract:

    Publisher Summary This chapter discusses the airworthiness requirements. The Basic Regulation establishes common requirements for the regulation of safety and environmental sustainability in civil aviation. It gives the European Commission powers to adopt detailed rules for the Regulation’s implementation. When the Joint Aviation Requirements (JAR) requirements were first issued in the 1970s, several different standards for Aircraft Certification were in force in different countries. The Federal Aviation Regulations (FARs) issued by the Federal Aviation Administration (FAA) were adopted in the United States. The list of JARS and FARS directly or indirectly related to airworthiness Certification includes: JAR 1/FAR 1. definitions and abbreviations, JAR 11. JAA regulatory and related procedures, FAR 11. general rulemaking procedure, JAR 21. Certification procedures for Aircraft and related products and parts, FAR 21. Certification procedures for products and parts, and JAR 22. sailplanes and powered sailplanes.

  • Airworthiness: An Introduction to Aircraft Certification
    , 2006
    Co-Authors: Filippo De Florio
    Abstract:

    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. Setting these requirements in a real-world context, Airworthiness is an essential contribution to the safety management system of anyone involved in the design, maintenance and operation of Aircraft for business or pleasure. 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 Joint Certifications and national Certifications New to this edition is coverage of: Certification for unmanned Aircraft systems (UAS) The new EASA standards procedures and documentation ‘Spaceworthiness’ with relation to recent developments in commercial space travel The only airworthiness guide available-a unique single reference covering the requirements of the ICAO (International Civil Aviation Organisation), FAA (the US Federal Aviation Administration) and EASA (European Aviation Safety Agency) Demystifies the relevant European and US regulations and helps anyone involved in the manufacture, flying and maintenance of Aircraft to understand this complex yet essential topic Now with companion website featuring links to pertinent sources for ease of reference and updates to the book as required, ensuring you have the most up-to-date information at your finger tips
