  2. Aircraft noise pollution - Wikipedia

    en.wikipedia.org/wiki/Aircraft_noise_pollution

    Noise-generating aircraft propeller. Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during takeoff, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.

  3. Noise pollution - Wikipedia

    en.wikipedia.org/wiki/Noise_pollution

    The FAA also pursues a program of aircraft noise control in cooperation with the aviation community. [112] The FAA has set up a process to report for anyone who may be impacted by aircraft noise. [113] The Federal Highway Administration (FHWA) developed noise regulations to control highway noise as required by the Federal-Aid Highway Act of ...

  4. EPNdB - Wikipedia

    en.wikipedia.org/wiki/EPNdB

    Detailed information on measurement of aircraft acoustic signature to meet the requirements of Annex 16 is found in ICAO Document 9501 [6] and IEC 61265. [7] Data acquisition in one-third-octave bands is required, followed by processing to yield a logarithmically-scaled value in decibels relative to a sound pressure of 20 micropascals for each one-third-octave band.

  5. Anti-Concorde Project - Wikipedia

    en.wikipedia.org/wiki/Anti-Concorde_Project

    Research by aeronautics engineer Bo Lundberg, Director of the Swedish Aeronautical Research Institute in the early 1960s suggested that sonic booms and aircraft engine noise would not be widely accepted. [a] The Anti-Concorde Project was founded in 1966 by Richard Wiggs (a school teacher) to oppose the development of supersonic passenger transport.

  6. Noise control - Wikipedia

    en.wikipedia.org/wiki/Noise_control

    Roadway noise and aircraft noise are the most pervasive sources of environmental noise. [2] Social activities may generate noise levels that consistently affect the health of populations residing in or occupying areas, both indoor and outdoor, near entertainment venues that feature amplified sounds and music that present significant challenges ...

  7. Radar jamming and deception - Wikipedia

    en.wikipedia.org/wiki/Radar_jamming_and_deception

    The most important method to counter radar jammers is operator training. Any system can be fooled with a jamming signal but a properly trained operator pays attention to the raw video signal and can detect abnormal patterns on the radar screen. The best indicator of jamming effectiveness to the jammer is countermeasures taken by the operator.

  8. Environmental impact of aviation - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    A short-range aircraft (< 2,000 km, 1,100 nmi) with hybrid Fuel cell/Turbines could reduce climate impact by 70–80% for a 20–30% additional cost, a medium-range airliner with H 2 turbines could have a 50–60% reduced climate impact for a 30–40% overcost, and a long-range aircraft (> 7,000 km, 3,800 nmi) also with H 2 turbines could ...

  9. Quota Count system - Wikipedia

    en.wikipedia.org/wiki/Quota_Count_system

    The quieter the aircraft the smaller the QC value. Aircraft are classified separately for landing and take-off. Take-off quota count values are based on the average of the certificated flyover and sideline noise levels at maximum take-off weight, with 1.75 EPNdB added for Chapter 2 aircraft. Landing quota count values are based on the ...
