The impact of increasing environmental concerns on the operation of aircraft and the aircraft maintenance industry

Noise pollution affects the people the most, the major side affect of the problem among a number of other aircraft operations and maintenance problems, compelling governments to reconsider the cost of mobility, economic growth and safety of their people. Airport expansion plans have suffered a set back because of increasing environmental impact on air quality, water quality and community noise (Waitz et al., 2004). Discussion Airport operations that affect environment include a number of functions such as the operation of aircraft, maintenance of airport and passenger vehicles and airport ground service equipment (GSE), cleaning and maintenance function, deicing and anti-icing of aircraft and airfields, fuelling and fuel storage of aircraft and other ground transport besides airport facility maintenance functions and airport construction (Luther, 2007). Airport authorities must consent to enforce environmental mitigation initiatives before asking permission for expansion of the airport from the local and state bodies. Community concern has shelved many expansion projects because of issues related to environment. Aviation related environment regulations have been in force from many years but these regulatory compliance issues have become very touchy to be implemented because of ever-increasing air travel. With the addition of new compliance needs airport operations have got transformed with huge investment needed and change in operation processes. Certain crucial issues have emerged due to noise pollution, changes in Environmental Protection Agency (EPA) regulations concerning aircraft and airfield deicing operations, changes to EPA regulations on oil spill preventive measures and state and local agency directives to inspect and manage air pollution, particularly harmful air pollutants (Luther, 2007). According to the Aeronautics and Space Engineering Board (ASEB, 2000), the aviation industry needs to look crucial current and future environmental issues such as: takeoff and approach noise causing various technology related issues for subsonic and supersonic aircraft flyover noise emerging from moderate speed and height in noiseless areas sonic booms and hyper booms caused by thermo-spherical refraction and reduced noise volume remains of sonic booms taxi and engine run-up noise fuel venting and fuel dumping emission of CO, hydrocarbons, and NOx in the airport area (below 3,000 feet) formation of vapour trail emissions of CO2 emissions in the upper troposphere and stratosphere from both subsonic and supersonic aircraft of water vapour, NOx, sulphur particles and carbon particles possibility for greenhouse effects and reduction in stratospheric ozone International Civil Aviation Organisation (ICAO, 2011) has defined the issue related to environmental concerns stating that emissions of aircraft engines are like any other emissions caused by fossil fuel burning but the difference between both types of emissions is that aircraft emissions are extra-ordinary as a good chunk is released at a height. Crucial environment concerns get raised for emissions’ worldwide impact, affecting the local air quality on the surface. As per the Special Report on Aviation and the Global Atmosphere published in 1999, the gases and particles released by the aircraft change the atmospheric density of greenhouse gases,
