Book excerpt: A flight guidance concept was developed to assist in flying continuous descent approach (CDA) procedures designed to lower the noise under the flight path of jet transport aircraft during arrival operations at an airport. The guidance consists of a trajectory prediction algorithm that was tuned to produce a high-efficiency, low noise flight profile with accompanying autopilot and flight display elements needed by the flight control system and pilot to fly the approach. A key component of the flight guidance was a real-time display of energy error relative to the predicted flight path. The guidance was integrated with the conventional Flight Management System (FMS) guidance of a modern jet transport airplane and tested in a high fidelity flight simulation. A charted arrival procedure, which allowed flying conventional arrivals, CDA arrivals with standard guidance, and CDA arrivals with the new low noise guidance, was developed to assist in the testing and evaluation of the low noise guidance concept. Results of the simulation testing showed the low noise guidance was easy to use by airline pilot test subjects and effective in achieving the desired noise reduction. Noise under the flight path was reduced by at least 2 decibels in Sound Exposure Level (SEL) at distances from about 3 nautical miles out to about 17.5 nautical miles from the runway, with a peak reduction of 8.5 decibels at about 10.5 nautical miles. Fuel consumption was also reduced by about 17% for the LNG conditions compared to baseline runs for the same flight distance. Pilot acceptance and understanding of the guidance was quite high with favorable comments and ratings received from all test subjects.Williams, David H. and Oseguera-Lohr, Rosa M. and Lewis, Elliot T.Langley Research CenterFLIGHT CONTROL; FLIGHT TESTS; JET AIRCRAFT; LOW NOISE; AIRCRAFT GUIDANCE; DESCENT; FLIGHT MANAGEMENT SYSTEMS; FLIGHT PATHS; RUNWAYS; SIMULATION; AUTOMATIC PILOTS; TRAJECTORIES; DISPLAY DEVICES; NOISE REDUCTION

Available in PDF, EPUB and Kindle. Book excerpt: In 2003, Congress directed the Secretary of Transportation to establish the Next Generation Air Transportation System (NGATS) Joint Planning and Development Office (JDPO) to plan the development of an air transportation system capable of meeting potential air traffic demand for 2025. All federal agencies involved in aviation participate in the JDPO providing the opportunity overcome many of the major barriers to developing an effective NGATS. To assist this process, the NRC was asked to examine the first NGATS Integrated Plan prepared by JPDO and submitted to Congress in 2004. This report provides a review of the vision and goals, the operational concepts, and the R&D roadmap developed by the plan; an analysis of the JDPO integrated product teams created to carry out the planning; and an assessment of the implementation process.

Book Synopsis Acoustic Flight Tests of Rotorcraft Noise-Abatement Approaches Using Local Differential GPS Guidance by : National Aeronautics and Space Administration (NASA)
Download or read book Acoustic Flight Tests of Rotorcraft Noise-Abatement Approaches Using Local Differential GPS Guidance written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-28 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the test design, instrumentation set-up, data acquisition, and the results of an acoustic flight experiment to study how noise due to blade-vortex interaction (BVI) may be alleviated. The flight experiment was conducted using the NASA/Army Rotorcraft Aircrew Systems Concepts Airborne Laboratory (RASCAL) research helicopter. A Local Differential Global Positioning System (LDGPS) was used for precision navigation and cockpit display guidance. A laser-based rotor state measurement system on board the aircraft was used to measure the main rotor tip-path-plane angle-of-attack. Tests were performed at Crows Landing Airfield in northern California with an array of microphones similar to that used in the standard ICAO/FAA noise certification test. The methodology used in the design of a RASCAL-specific, multi-segment, decelerating approach profile for BVI noise abatement is described, and the flight data pertaining to the flight technical errors and the acoustic data for assessing the noise reduction effectiveness are reported.
