Development And Initial Evaluation Of A Reinforced Cue Detection Model To Assess Situation Awareness In Commercial Aircraft Cockpits, Aysen K. Taylor

Engineering Management & Systems Engineering Theses & Dissertations

Commercial transport aircraft of today vary greatly from early aircraft with regards to how the aircraft are controlled and the feedback provided from the machine to the human operator. Over time, as avionics systems became more automated, pilots had less direct control over their aircraft. Much research exists in the literature about automation issues, and several major accidents over the last twenty years spurred interest about how to maintain the benefits of automation while improving the overall human-machine interaction as the pilot is considered the last line of defense.

An important reason for maintaining or even improving overall pilot situation …

Efvs Effects On Pilot Performance, Michael Campbell, Nsikak Udo-Imeh, Steven J. Landry

The Summer Undergraduate Research Fellowship (SURF) Symposium

Flight tests have been conducted at Purdue University using a computer-based flying simulator in an attempt to determine and measure the effects of Enhanced Flight Vision Systems (EFVS) on the performance of pilots during landing. Knowledge of these effects could help guide future design and implementation of EFVS in modern commercial aircraft, and further increase pilots’ ability to control the aircraft in low-visibility conditions. The problem that has faced researchers in the past has revolved around the difficulty in interpreting the data which is generated by these tests. The difficulty in making a generalized conclusion based on the large amount …

Skycsr: Optimal Communication Methods For Coordinating Ground Support In A Private And General Aviation Setting, Jessica Burke

Industrial and Manufacturing Engineering

Delays due to miscommunication of between the pilot and ground service providers are increasing. The objective of this project is to develop a new method of communication between pilots, line service technicians and customer service agents. This will be achieved first through an investigation into current methods and state of the industry, followed by a survey conducted with a group of pilots and flight schools. This culminates in a web application that will take the deficiencies identified in the survey, to make sure ground service or fuel orders are explicitly clear and minimize the probability of a mis-fueling, overlooked fueling, …

Assessing Aviation E-Marketplaces: A Mmulti-Criteria Approach., Emilio Esposito, Pietro Evangelista, Michele Mastroianni, Renato Passaro, Edward Sweeney, Claudia-Maria Wagner

Books/Book chapters

After a proliferation of logistics e-Marketplaces during the dot.com boom of 1998-2000, there has been a high rate of failure and survivals are developing much more slowly than expected. This is the case in the aviation industry where a large number of B2B e-Marketplaces emerged according to the focus of aviation companies’ strategies on electronic B2B in the late 1990s. However, the current use of e-Marketplaces in the industry is low and many of them have ceased trading. The traditional e-Marketplaces model has been characterised by poor quality portals and a lack of technical standards. Such an approach is unsustainable …

Pilot Weather Decision Making And The Influence Of Passenger Pressure, Jaclyn Baron

All Dissertations

The purpose of this study is to determine the effect of social pressure on general aviation (GA) pilots' weather decision making. Data have shown that GA accidents associated with visual flight rules (VFR) flight into instrument meteorological conditions (IMC) are more likely to result in fatalities than other types of GA accidents. This problem is compounded by the addition of passengers, who have been found to be present onboard during VFR into IMC accidents more frequently than in other types of GA accidents. The question is whether passengers influence a pilot's decision to continue flight into adverse weather. The extent …

A Scanpath Comparison Of The Salient Features Of Weather Among General Aviation Pilots Based On Training And Experience, Michael Sawyer

All Dissertations

Over the last 20 years the number of annual accidents in general aviation has seen a steady decline. The annual number of fatal accidents, however, has remained relatively stable. Adverse weather is consistently cited as a leading cause of fatal accidents in general aviation; weather accidents have a fatality rate nearly four times that of other general aviation accidents. Reviews of accident data reveal that often these accidents occur when inexperienced pilots who are certified only for visual flight rules flight continue into adverse weather. The Situation Assessment Hypothesis suggests these accidents occur when pilots fail to accurately recognize weather …

Effective Vr: Interplay Of Presence, Perception, Fidelity And Transfer Effects In The Development Of Inspection Training Simulators, Sajay Sadasivan

All Dissertations

Increased emphasis on aircraft inspection to ensure aviation safety has resulted in the need for a better trained workforce of aircraft maintenance personnel.
