aircraft emissions Articles

A wide range of publications has shown that the tourism sector is increasingly environmentally unsustainable. This is mainly caused by the contribution of aviation to a large and growing amount of Greenhouse Gas (GHG) emissions by tourism. In the light of this, we present an overview of developments in the aviation sector and discuss current options for innovation towards sustainability in three ...

In this study, global warming potential (GWP) is calculated for aircrafts used in Turkish airports. The basic idea of this study is to investigate both emissions and their GWP values. This study is conducted in three steps, namely: 1) finding busiest airports in Turkey; 2) specifying the most used aircraft types and its engines; and 3) calculation of domestic flight-caused GWP value for both the ...

The recent decision by the EU Parliament supporting an emissions tax and subsequent carbon trading scheme for European airlines provides the structural foundation for an exploration of the role of Coasian economics in emissions abatements in the international aviation industry. The paper begins by outlining Pigouvian taxation in aviation and considers, from a business context, the potential ...

The long awaited standard for aircraft CO2 emissions made further headway at a recent meeting of the UN’s International Civil Aviation Organization (ICAO). The new environmental measure was unanimously recommended by the 170 international experts on ICAO’s Committee on Aviation Environmental Protection (CAEP), paving the way for its ultimate adoption by the UN ...

Air quality modelling near airports has received attention due to the impact of emissions from aircrafts near ground level. This work is part of the model inter-comparison study undertaken for the Department of Transport in connection with air quality near Heathrow Airport. Results formed part of a submission to the UK government in July 2006. The Emissions and Dispersion Modelling System (EDMS) ...

In May 1992, the new airport in Munich, Germany, became fully operational. In 1991, two research programmes within the Bavarian Climate Research Programme (BayFORKLIM) in Germany/Bavaria were established to measure, calculate and model the assumed change of the air quality in the vicinity of the new airport. By analysing the synoptic and local weather situation, measured and modelled air ...

ADMS-Airport is based on the ADMS-Urban system for modelling urban air quality. In the near field it employs a quasi-Gaussian dispersion model and this is nested within a trajectory model. Aircraft sources are treated explicitly as accelerating jets. Application of the model to air quality calculations was conducted for the Model Inter-Comparison (MIC) Study of Project for the Sustainable ...

The environmental effects of exhaust gas emissions from different types of spark ignitions (SIs) - naturally aspirated and air–cooled from piston–prop aircraft engines - at the landing and take–off (LTO) phase of flight–based operations are investigated in this study. The minimum natural resources effect was determined to be 1.37 MJ surplus energy/LTO in 320 in three cylinder displacement and ...

This paper presents a comparison of modelled and measured annual mean NO2 concentrations around Zurich airport. Modelled concentrations were derived from the LASAT Lagrangian model for the airport and from a Gaussian plume model for the Zurich canton. The measured annual mean NO2 concentrations were monitored at stations within the airport. The modelled airport NO2 concentrations fell below 1 ...

8. Mathematical algorithms   The mathematical model that the software uses provides options to model noise emissions from a wide range of sources that might be present at industrial areas and urban areas.   The basis of the model is the linear sound propagation  equation, which is used to model simple point source emissions from vehicles, industries, aircrafts,… ...

The gaseous and nonvolatile particulate matter (PM) emissions of two T56-A-15 turboprop engines of a C-130H aircraft stationed at the 123rd Airlift Wing in the Kentucky Air National Guard were characterized. The emissions campaign supports the Strategic Environmental Research and Development Program (SERDP) project WP-1401 to determine emissions factors from military aircraft. The purpose of the ...

A Rapid-Scanning Backscatter Lidar (RASCAL) has been deployed at Heathrow and Manchester Airports to collect backscatter data from particulate emissions in the wakes of several hundred flights. The principal aim of these measurements was to characterise the dispersion of the engine exhausts, but it was found that tyre smoke was also visible, giving a signal substantially greater than that from ...

INTRODUCTION NPL is one of a number of laboratories which forms part of the Governments policy to ensure that UK measurements of all kinds are accurately made through the DTI’s National Measurement System. NPL is the focus of the United Kingdom’s physical measurements and its remit includes aspects of environmental measurements, ...

Late last month, the World Trade Organisation told the USA and the EU what it thinks of US subsidies to Boeing (story, page 2). Last June, the WTO delivered a similar verdict on EU subsidies to Airbus. Of course both sides claim that the other’s subsidies are worse – we can’t yet check these claims because the WTO report won’t be published for another few weeks, but it is ...
