Examining How Breakdowns In Pilot Monitoring Of The Aircraft Flight Path, Robert Sumwalt, David Cross, Dennis Lessard Aug 2015

Examining How Breakdowns In Pilot Monitoring Of The Aircraft Flight Path, Robert Sumwalt, David Cross, Dennis Lessard

International Journal of Aviation, Aeronautics, and Aerospace

Aircraft accident and incident data reveal that serious safety consequences can arise when flight crewmembers fail to properly monitor the aircraft flight path. This research study reviewed human factors literature to better understand why pilots fail to properly monitor, and analyzed accident and incident data. Recommendations for improving monitoring performance were formulated, which may be useful to air carriers in implementing a new Federal Aviation Administration requirement that calls for specific training in monitoring.


Bio-Fuel Alternatives In South African Airways (Saa) Operations - Is It An Effective Response To Vulnerability Over Carbon Taxes And Penalty?, Daniel Kwasi Adjekum Jul 2015

Bio-Fuel Alternatives In South African Airways (Saa) Operations - Is It An Effective Response To Vulnerability Over Carbon Taxes And Penalty?, Daniel Kwasi Adjekum

International Journal of Aviation, Aeronautics, and Aerospace

The paper did a comparative analysis of the carbon emission and European Union Emission Trading Surcharges (EU ETS) of South African Airways (SAA) current fleet that used aviation jet A1 fuel and the same fleet if it had used a 25% bio-fuel ‘drop in’ for the European routes within the first quarter of the 2014 flying year (FY 14). Operational data in terms of the flight scheduled, aircraft type, total time enroute, route stage length, passenger estimates were obtained through SAA’s flight operations website. An independent t–test was conducted to compare means of the emissions. The mean carbon dioxide …


Efficient General Computational Method For Estimation Of Standard Atmosphere Parameters, Nihad E. Daidzic Ph.D., Sc.D. Mar 2015

Efficient General Computational Method For Estimation Of Standard Atmosphere Parameters, Nihad E. Daidzic Ph.D., Sc.D.

International Journal of Aviation, Aeronautics, and Aerospace

Knowledge of standard air temperature, pressure, density, speed of sound, and viscosity as a function of altitude is essential information in aircraft design, performance testing, pressure altimeter calibration, and several other aeronautical engineering and aviation science applications. A new efficient computational method for rapid calculations of standard atmospheric parameters up to 86 orthometric km is presented. Additionally, mass and weight of each standard atmospheric layer were calculated using a numerical integration method. The sum of all fractional masses and weights represents the total mass and weight of Earth’s atmosphere. The results obtained here agree well with measurements and models of …


Regional Aviation Early Career Pilot Attributes Study, Stewart Wayne Schreckengast, Douglas A. Drury Feb 2015

Regional Aviation Early Career Pilot Attributes Study, Stewart Wayne Schreckengast, Douglas A. Drury

International Journal of Aviation, Aeronautics, and Aerospace

The Regional Aviation Association of Australia (RAAA) has identified a need to better understand the concerns of its members in the attraction and retention of early career pilots. RAAA has further identified the need to better understand any shortcomings in professional aviation training programs in Australia so as to provide appropriate guidance from an industry point of view. The RAAA Training and Education Committee (TEC) facilitated the undertaking of this study with its members. This study provides insight into the technical and non-technical attributes that aviation manager’s value in early career pilots.


Situational Leadership Styles In United States Air Force Air Traffic Control Towers, William D. Melton, Chad L. Depperschmidt, Timm J. Bliss Dec 2014

Situational Leadership Styles In United States Air Force Air Traffic Control Towers, William D. Melton, Chad L. Depperschmidt, Timm J. Bliss

International Journal of Aviation, Aeronautics, and Aerospace

Leadership in air traffic control facilities is critical to the safe, orderly, and efficient flow of air traffic. The purpose of this qualitative study was to determine the preferred leadership style for United States Air Force air traffic control tower watch supervisors. A panel of 10 functional experts completed a 25 question scenario-based survey to establish a baseline for this study’s four research questions. A purposeful sample of eight control tower chief controllers representing the eight United States Air Force major commands were interviewed and their responses were compared to the mean of the experts panel. The data from the …


Reliability Of Eyewitness Reports To A Major Aviation Accident, Dave English, Michael Kuzel Nov 2014

Reliability Of Eyewitness Reports To A Major Aviation Accident, Dave English, Michael Kuzel

International Journal of Aviation, Aeronautics, and Aerospace

There is a paucity of studies on the reliability of eyewitness reports to aviation crashes. We examine witness statements to a widely observed major airline accident to determine if reported accident investigator distrust of details in eyewitness reports is supported by empirical evidence. The extensive archival witness record (N > 300) of a wide-body airliner crash in clear daylight conditions is subjected to statistical analysis to test eyewitness reliability. Even with over 200 witnesses within a three square kilometre (1.6 square mile) area answering a binary observation question, the variance is sometimes high enough to preclude forming statistically significant conclusions …
