This book was released on 2012 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a guide for airport operators on effective procedures for using air quality models in combination with on-site measurement equipment to prepare a comprehensive assessment of air pollutant concentrations in the vicinity of airports. It is designed to help practitioners generate information desired by local communities as they seek to develop more detailed local air quality assessments as well as respond to regulatory needs, including those of the National Environmental Policy Act (NEPA). The guide provides in-depth information on the capabilities and limitations of modeling and measurement tools, adding to an increasing knowledge base concerning preparation of air quality assessments near airports. Starting with the Federal Aviation Administration's (FAA) regulatory EDMS/AEDT, it describes how best to use available models, in combination with potential on-site monitoring programs, to conduct air quality assessments. Detailed information on the monitoring campaigns and modeling assessments is included in a set of appendices that accompany the guide. The appendices (available in CRP-CD-115) describe the models tested and the various equipment used to collect data, the rationale behind the selection of Washington Dulles International Airport as a case study application, and the components and steps involved in the measurement campaigns, and include an assessment of the various model outputs--

Download or read book Airport Vicinity Air Pollution Study The Impact of Modified Aircraft Taxi Procedures on Airport Air Quality written by Richard R. Cirillo and published by . This book was released on 1974 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an analysis of an aircraft ground operation control measure designed to reduce air pollutant emissions. In a demonstration program conducted at the Atlanta Airport, turbine-powered air carrier aircraft taxied on one less engine than normal with the remaining engines at higher thrust settings. Observations made at the airport during the field test are used to estimate the total reduction in engine operating time and the equivalent reduction in emissions. The Argonne Airport Vicinity Air Pollution Model is used to calculate the improvement in air quality resulting from the test program. The model is a Gaussian-plume-type dispersion model that utilizes point, area, and line source formulations to simulate the complex airport system. Comparison is made with air quality data collected both before and during the modified taxi test for model validation.

Book excerpt: This report documents the results of the Federal Aviation Administration (FAA)/Environmental Protection Agency (EPA) air quality study which has been conducted to assess the impact of aircraft emissions of carbon monoxide (CO), hydrocarbons (HC), and oxides of nitrogen (NOx) in the vicinity of airports. This assessment includes the results of recent modeling and monitoring efforts at Washington National (DCA), Los Angeles International (LAX), Dulles International (IAD), and Lakeland, Florida airports and an updated modeling of aircraft generated pollution at LAX, John F. Kennedy (JFK) and Chicago O'Hare (ORD) airports. The Airport Vicinity Air Pollution (AVAP) model which was designed for use at civil airports was used in this assessment. In addition the results of the application of the military version of the AVAP model the Air Quality Assessment Model (AQAM), are summarized.

This book was released on 1984 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first part of this report addresses the status of the AVAP (Airport Vicinity Air Pollution) model and AQAM (Air Quality Assessment Model) from the perspective of the modeling requirements of users concerned with air-quality problems in civilian and military aviation. Brief descriptions of the types of problems likely to be encountered is followed by a detailed discussion of those characteristics of the problems that determine the technical requirements for the applicable computation procedures or models. This is followed by a discussion of the operational or user requirements of the models. Then a review and evaluation of the AVAP model and AQAM is given that includes a discussion of their intended uses, strengths, and weaknesses. The methods used by the two models to treat various aspects of the emission and dispersion are compared, and the best methods are selected, or alternatives are recommended where appropriate. The latter portion of the report addresses the future needs. Because of the number of interrelated problems and decisions required to meet these needs, a systematic approach to the problem in the form of a 'decision tree' is presented. The final section contains an outline of a proposed new computational system that should alleviate at least some of the problems identified in earlier sections. Two objections were paramount in the new design: to make the model easier to use and to be able to implement the model on modern, small computers.

Download or read book Air Quality Impact Analysis of a Proposed North South Runway at Anchorage International Airport written by John E. Tigue and published by . This book was released on 1975 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents an air quality analysis of the impact of a proposed runway at Anchorage International Airport. A projection of 1978 air traffic conditions was made and the Airport Vicinity Air Pollution (AVAP) model was used to calculate the aircraft impact upon air quality for cases with and without the proposed runway. The AVAP model is a Gaussian-plume-type dispersion model that utilizes point, area, and line source formulations to simulate the airport system. The air quality impact is evaluated by comparing the air quality concentrations for the case with the proposed runway to the case without the runway. Typical Anchorage days where the meteorology is poor were selected such that rather poor air quality would result. The study indicates that the addition of the proposed runway does not make a significant impact upon the airport vicinity air quality. Areas of concern do exist on the airport itself, but the impact on the communities surrounding Anchorage International Airport is minimal. (Author).

Book excerpt: Although airports provide several benefits for our society, communities in the vicinity of airports are subjected to the deterioration of air quality. Currently, the basic objects of attention are NOx and ultrafine PM due to airport-related emissions. Considered environmental problems are intensified in connection with increasing air traffic, rising tensions of airports expansion and growing cities closer and closer each other, and accordingly growing public concern with air quality around the airport. Aircraft are the dominant and special source of emission and air pollution at airports in most cases under consideration. So, to evaluate the aircraft contribution in LAQ assessment of the airports accurately, it is important to take in mind few features of the aircraft during their landing-takeoff cycle (LTO), which define emission and dispersion parameters of the considered source. The complex model PolEmiCa allows the calculation of the inventory and dispersion parameters of the aircraft engine emissions during the LTO cycles of the aircraft in the airport area. But a clear quantification of aircraft emission contribution to total air pollution is the actual task for development of cost-effective strategies to improve local air quality according to the vicinity of the airport, and to meet regulatory requirements.
