An Analysis of the Factors Influencing Score Achieved during Pilot Training
(Japan Soc Aeronaut Space Sci, 2017)Human error is considered a causal or contributory factor in a major part of aviation incidents. It's also known from relevant research and reports that even the smallest error made by a person can cause fatal results in ... -
Resource Dependency Risk Management
(Springer-Verlag Singapore Pte LTD, 2017)Resources are vital for any business. To survive, organizations have to both use and allocate some resources. Resource availability is one of the biggest uncertainty sources for managers. To get optimum resources from ... -
Aircraft fuel system energy and exergy analysis under hot day conditions
(Inderscience Enterprises LTD, 2018)In this paper, energy and exergy analysis of the fuel system is performed to investigate the variation of flow and heat energies of fuel. Thermal balance, formed by many different components of aircraft systems by means ... -
Critical Event Stress Management
(Springer-Verlag Singapore Pte LTD, 2017)Stress has considerable potential to affect individuals. Humans mostly reflect their own stress on their work, family, environment and personal lives. Stress is a kind of risk source since it creates differentiated reactions ... -

Partial substitution of hydrogen for conventional fuel in an aircraft by utilizing unused cargo compartment space
(Pergamon-Elsevier Science LTD, 2010)Options are being actively sought in aviation to switch from petroleum-based fuels to alternative fuels, of which hydrogen is a promising candidate, despite challenges associated with its production and storage. The ... -
Assessment of emissions at busy airports
(John Wiley & Sons LTD, 2010)Emissions are determined in the vicinity of airports and used to demonstrate that aircraft movements in the airport, as measured by landings and takeoffs, are not sufficient to evaluate the cumulative emission formation ... -
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 ... -
Exergy analysis of a turbofan aircraft engine
(Inderscience Enterprises LTD, 2009)An exergy analysis is reported for a General Electric turbofan engine (the CF6-80) using sea-level data. The effects on exergy efficiencies and exergy destructions are investigated of modifying the isentropic efficiencies ... -
Exergoeconomic analysis of an aircraft turbofan engine
(Inderscience Enterprises LTD, 2009)This study deals with an exergoeconomic analysis of an aircraft turbofan engine utilising the kerosene as fuel. A new parameter is developed to define the trust cost rate. The cost of exergy destruction, the relative cost ... -
A Preliminary Study on Relationship between Flight Path Angle and NOx Emissions during Descent
(Aidic Servizi Srl, 2014)Interest in the continuous descent approach has recently increased due to opportunities it provides for fuel savings and emissions and noise control. However, the implementation of this procedure involves a number challenges ... -
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 ... -
Emissions at Busy Airports
(World Scientific And Engineering Acad And Soc, 2009)Emissions in the vicinity of airports demonstrate that aircraft movements (landings and takeoffs in the airport are not sufficient to evaluate the cumulative emission formation for an airport. Eight busy airports and three ... -
