TL;DR: In this paper, the implications of new environmental policies in conjunction with airline deregulation and change in the airport infrastructure are examined, focusing on the specifics of Sydney Kingsford Smith Airport, and broader policy issues likely to be relevant for other major airports around the world are discussed.
Abstract: This paper provides an empirical examination of the implications of new environmental policies in conjunction with airline deregulation and change in the airport infrastructure. This paper discusses principles and policy analyses. By focusing on the specifics of Sydney Kingsford Smith Airport, broader policy issues likely to be relevant for other major airports around the world are discussed.

TL;DR: In this paper, the authors focus on the high-lift noise component associated with a leading-edge slat; flap side-edge noise is discussed in a companion paper by Streett et al. and consider both tonal and broadband aspects of slat noise.
Abstract: The synergistic use of experiments and numerical simulations can uncover the underlying physics of airframe noise sources. We focus on the high-lift noise component associated with a leading-edge slat; flap side-edge noise is discussed in a companion paper by Streett et al. (2003). The present paper provides an overview of how slat noise was split into subcomponents and analyzed with carefully planned complementary experimental and numerical tests. We consider both tonal and broadband aspects of slat noise. The predicted far-field noise spectra are shown to be in good qualitative (and, to lesser extent, good quantitative agreement) with acoustic array measurements. Although some questions remain unanswered, the success of current airframe noise studies provides ample promise that remaining technical issues can be successfully addressed in the near future.

TL;DR: In this article, a novel simulation theory for a complete fixed-wing aircraft is presented, which addresses a shortfall in multi-disciplinary integration in aircraft flight, including economic operations, preliminary design and environmental emissions.
Abstract: This contribution presents a novel simulation theory for a complete fixed-wing aircraft.
Novel methods are presented for flight mechanics
(fuel planning), turbofan engine simulation (in
direct and inverse mode), thermo-physics
integration (tire temperature on the ground and
fuel temperature in flight) and aircraft noise. At the fundamental level, the framework presented addresses a shortfall in multi-disciplinary integration in aircraft flight, including
economic operations, preliminary design and
environmental emissions. Validation strategies
are introduced for component-level analysis and
system integration. Results are presented for geometry models, specific air range and optimal
cruise conditions, payload-range performance,
fuel temperature of a wing tank, tire heating during normal take-off, aircraft propulsive
(jet/nozzle) and non propulsive (landing gear)
noise. Selected results are shown for the Boeing
B777-300 and the Airbus A380-861.

TL;DR: Sleep quality in participants residing near an airfield is determined and the relationship between the levels of aircraft noise and sleep quality is evaluated through a large-scale follow-up study.
Abstract: Objectives
Exposure to aircraft noise has been shown to have adverse health effects, causing annoyance and affecting the health-related quality of life, sleep, and mental states of those exposed to it. This study aimed to determine sleep quality in participants residing near an airfield and to evaluate the relationship between the levels of aircraft noise and sleep quality.
