What Are The Predictors Of System-Wide Trust Loss In Transportation Automation?, Stephen Rice, Scott R. Winter, John E. Deaton, Ismael Cremer
Publications
Prior research has examined how individuals place trust in single (e.g., Meyer, 2001, 2004) and multiple (e.g., Geels-Blair, Rice, & Schwark, 2013) automated devices when one fails. This has shown that participants are influenced by system-wide trust (SWT). What has been missing is an investigation into what types of people succumb to SWT effects. The current study attempts to replicate SWT findings and identify possible predictors of individuals likely to be influenced by SWT. The findings did demonstrate a replication of SWT. The study found that ‘‘feelings of negativity when automated devices fail’’ was a significant predictor of SWT theory.

Determination Of Rejected Landing Roll Runway Point-Of-No-Return And Go-Around In Transport Category Airplanes, Nihad E. Daidzic, Ph.D., Sc.D.
International Journal of Aviation, Aeronautics, and Aerospace
The decelerate-accelerate-takeoff maneuver in transport category airplanes has been discussed. Mathematical model based on total energy conservation has been used to calculate the rejected landing point-of-no-return on a runway which will still enable the airplane to safely execute go-around and achieve regulatory screen heights and takeoff safety speeds. After this point has been exceeded or below the point-of-no-return speed no go-around should ever be considered. Landing long and fast and/or decelerating on slippery runways may very well result in an overrun which could be prevented if the go-around is attempted before reaching this critical runway point. The point-of-no-return on the …

General Solution Of The Wind Triangle Problem And The Critical Tailwind Angle, Nihad E. Daidzic
Aviation Department Publications
A general analytical solution of the navigational wind-triangle problem and the calculation of the critical tailwind angle are presented in this study among other findings. Any crosswind component will effectively create a headwind component on fixed course tracks. The meaning of a route track is lost with excessive crosswinds representing the bifurcation point between the possible and the impossible navigational solutions. Any wind of constant direction and speed will effectively reduce groundspeed and increase time-of-flight on closed-loop multi-segment flights. Effective wind track component consists, in general, of true and induced components. The average groundspeed of multiple-leg flights is a harmonic …

Comparison Of Renting Training Aircraft Using Data Envelopment Analysis, Heather Dickerson
Undergraduate Review
Many elements are involved when a pilot is trying to decide which aircraft to pursue for rental. Uninformed new pilots decide to rent purely based upon the aircraft used for initial training, but once more variables are considered, the pilot will realize such an important decision must consider all aspects. Cost typically being the greatest determining factor, horsepower output of the engine, speed, the maximum load capacity, and the maximum altitude the aircraft is able to reach also tend to have a large effect on determining which aircraft will suit the needs of the pilot. Data Envelopment Analysis was used …

Judging Airline Pilots’ Performance With And Without An Assessment Model: A Comparison Study Of The Scoring Of Raters From Two Different Airlines, David Weber
Journal of Aviation/Aerospace Education & Research
Various models have been suggested to assess the performance of airline pilots. However, the influence of a model on assessors’ scoring remains largely unexplored. The aim of the present study was to contrast the assessments of raters from two airlines, who assessed performance in pairs of the same airline and rank by using or not using an assessment model. The results showed differences between the assessors of the two airlines in terms of their scoring. Implications were drawn in regards to the usage of a model and its influence on pilot performance assessment.

Effects Of Automation On Aircrew Workload And Situation Awareness In Tactical Airlift Missions, David R. Meyer
Theses and Dissertations
In tactical aviation, decision superiority brought upon by high situation awareness remains the arbiter of combat effectiveness. The advancement of sophisticated avionics and highly automated cockpits has allowed for the reduction of aircrew size, and in certain platforms, removal of the crew from the aircraft entirely. However, these developments have not reduced the complex and dynamic interaction between situation awareness and crew workload. While many predictive and experimental methods of evaluating workload exist, situation awareness can only be measured by conducting trials with human operators in a functional prototype. This thesis proposes an innovative methodology to predicatively determine situation awareness …

Momentum Of Particles From Time-Of-Flight Measurements, Joseph Best
Senior Theses
In order to find the momentum of particles from time of flight measurements, I used a program called Geant4 to simulate experiments. I made a simple two detector setup, and I recreated a real world experiment. I spent a lot of time learning to code in C++ so I could use Geant4 correctly. I simulated these experiments shooting electrons, muons, and pions through the geometry and measured the time at two points in their flight. Subtracting the second time from the first gave me the time of flight distribution for each particle. I used ROOT to draw histograms of the …

Causes And Trends In Maintenance-Related Accidents In Faa-Certified Single Engine Piston Aircraft, Douglas Boyd, A. Stolzer
Alan J. Stolzer
The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question. The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR Part 91. Pearson Chi-Square, Fisher’s Exact Test, and Poisson probability were used in statistical analyses. The rate of maintenance-related general aviation accidents was 4.3 per million flight hours for the 1989–1993 period and remained unchanged for the most recent period (2009–2013). Maintenance errors …

Marbles: The Application Of Input-Output Concepts To Safety Management Systems, Tim Brady, A. Stolzer, Anthony Brickhouse, Antonio Cortes, Dan Mccune, Jayathi Raghavan, David Freiwald
Alan J. Stolzer
The goal of this research was to apply the economic concept titled Input-Output Analysis to an aviation safety concept titled Safety Management Systems (SMS). Input-Output (IO) is based upon the interrelationships of various components of an economic system and what happens to the system when one or more of those components changes. Since SMS is, by definition, a system with definable components, the research sought to determine if the interrelationships between those components could be determined and quantified. The term ‘‘marbles’’ was used to describe the activities that led to the IO-SMS matrix. Marbles was used as a metaphor for …

Market Analysis For Small And Mid-Size Commercial Turboprop Aircraft, Vitaly Guzhva, Tamilla Curtis, Vladislav Borodulin
Dr. Tamilla Curtis
Recent fuel price volatility and growing concerns about the efficiency of regional jets have led to a revival of large turboprop aircraft as efficient passenger carriers on short-haul regional routes. However, the overall market for smaller turboprops is much less defined as it is characterized by a plethora of small commuter and niche operators in addition to regional carriers. Since most small and mid-size turboprop manufacturers have gone bankrupt or discontinued production due to some other reasons, current operators of this aircraft class are left with aging fleets that would need to be replaced by 2020-2030. This paper assesses the …
