Empirical analysis of the effect of descent flight path angle on primary gaseous emissions of commercial aircraft
(Elsevier Sci LTD, 2018)
In this study, the effects of descent flight path angle (between 1.25 degrees and 4.25 degrees) on aircraft gaseous emissions (carbon monoxide, total hydrocarbons and nitrogen oxides) are explored using actual flight data ...
Emission Benefits of Continuous Descent Approach
(World Scientific And Engineering Acad And Soc, 2009)
The approach phase often has the most fuel savings potential among the other phases such as takeoff, climbout, cruise and ground operations. Therefore, the main objective of this study is to investigate being close to the ...
Estimation of vertical and horizontal distribution of takeoff and climb NOx emission for commercial aircraft
(Pergamon-Elsevier Science LTD, 2013)
An investigation of takeoff and climb NOx emissions is reported for a twin-engine, narrow-body, short-to-medium haul commercial aircraft, B737-800. Ten randomly selected flights are considered for two independent domestic ...
An Analysis of Vertical Profiles of Wind and Humidity Based on Long-Term Radiosonde Data in Turkey
(2016)
The prediction of atmospheric variables is fundamentally important for flight, and efficiency with environmental impact analyses of aircraft. However, certain variables are less predictable leading to inefficient utilization ...
Fuel flow analysis for the cruise phase of commercial aircraft on domestic routes
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2014)
From the point of view of the environmental impact of aviation, rather than fundamental strategies mainly intended for lower fuel consumption, and thereby less carbon dioxide emissions, more comprehensive approaches have ...
Effect of vertical profile inefficiency during descent on fuel burn, emissions and flight time
(Cambridge University Press, 2018)
Vertical profile inefficiency caused by low-level flight segments during arrival and departure operations has a great impact on the financial cost of operators as well as negative environmental effects. In this regard, ...
The effect of flight distance on fuel mileage and CO2 per passenger kilometer
(Taylor & Francis Inc, 2019)
In this study, the effect of distance on fuel mileage (fuel burn per nautical mile) and CO2 intensity, based on a large amount of actual flight data, is discussed for narrow-body commercial aircraft performing domestic ...
Effect of Climb Angle on Aircraft Fuel Consumption and Nitrogen Oxides Emissions
(Amer Inst Aeronautics Astronautics, 2018)
Departure climb angles differ with respect to factors such as obstacles within the departure track, meteorological conditions, and cost index input, most of which have a dynamic nature to some extent. In this sense, it is ...
Arrival traffic sequence for converging runways
(Springer International Publishing, 2016)
Vectoring, automated methods and speed control are available sequencing methods defined by International Civil Aviation Organization (ICAO). Point Merge System (PMS) is an innovative method for merging and sequencing arrival ...
Analysis of Test-Cell Emission Measurements of Newly Overhauled Turbofan Engines
(Amer Inst Aeronautics Astronautics, 2015)
In this study, the gaseous emissions of newly overhauled CFM56-3B1 and -3B2 series turbofan engines are measured in a test-cell environment during typical functional and performance test procedures. The measured emissions ...
