The Cognition Of Multi-Aircraft Control (Mac): Proactive Interference And Working Memory Capacity, Kelly Amaddio, Michael Miller, John Elshaw, Victor Finomore

International Symposium on Aviation Psychology - 2015

As the number of U.S. Air Force missions requiring UAVs has rapidly increased without commensurate increases in manpower, systems which permit a single operator to supervise and control multiple, highly-automated aircraft are being considered. The operator of such a system may be required to monitor and respond to voice communications for multiple UAVs, each of which can have aircraft specific call signs, which may impose excessive requirements on constrained operator attention, working memory, and cognitive processing. The current research investigates the cognitive load (number of aircraft call signs) an individual can handle and explores the effect of proactive interference (PI) …

Statistical Errors In Aviation Psychology: Commonsense Statistics In Aviation Safety Research, Christopher D. Wickens

International Symposium on Aviation Psychology - 2015

I discuss problems with the use of null hypothesis significance testing, as it is particularly applied to safety research such as that in aviation psychology. Such problems are manifest in the inherent bias of traditional statistics to avoid type 1 statistical errors, and hence to discourage findings of safety improving effects as significant, when low powered experimental designs are required by necessary constraints. In contrast, I offer several approaches or remedies. Researchers should think about the decisions made by consumers of their research, based on the costs and values of those decisions; they should form alternative hypotheses, use smart planned …

Requirements For Developing The Model Of Spatial Orientation Into An Applied Cockpit Warning System, Ben D. Lawson, Braden J. Mcgrath, Michael C. Newman, Angus H. Rupert

International Symposium on Aviation Psychology - 2015

Refinements have been made to a model of spatial disorientation (SD) to improve simulation of acceleration stimuli and visual-vestibular interactions. The improved model has been applied to aviation mishaps. The model is considered a technological countermeasure for SD because it is implemented as prototype software to aid the identification of mishap contributors in a way that should benefit didactic training. There is a more direct way this countermeasure can prevent SD, which is by adapting it for use as part of a cockpit warning system. The idea is to expand the model from one which explains mishaps post-hoc into one …

The Volpe Center developed a questionnaire to examine the representativeness of symbol shapes and the usefulness of information depicted on Low Visibility Operations/Surface Movement Guidance and Control System (LVO/SMGCS) paper charts. One-hundred forty-four pilots were shown a series of symbol shapes and responded “Yes” or “No” to whether they considered each symbol shape representative of a given information type. Symbol shapes were presented at increasing levels of context. Pilots then rated the usefulness of information depicted on LVO/SMGCS charts. Pilots identified representative symbol shapes for a geographic position marking, instrument landing system (ILS) hold line, runway guard lights (RGL), stop …

A Valid And Reliable Safety Scale For Passenger’S Perceptions Of Airport Safety, Stephen Rice, Rian Mehta, Scott Winter, Korhan Oyman

International Symposium on Aviation Psychology - 2015

Previous research has developed various customer satisfaction scales in many applied areas; however, to our knowledge, there is not a validated scale for measuring commercial airline passengers’ ratings of personal safety based on airport security. The current study seeks to address this missing gap by developing a valid and reliable safety scale for commercial airline passengers (SS-CAP). We first solicited words and phrases that are related to a passenger’s feeling of safety from potential consumers and experts in the field. We then narrowed down the list to 7 remaining items. Lastly, we tested the scale using participants from Amazon's ® …

An Evaluation Of The Utility Of At-Sat For The Placement Of New Controllers By Option, Cristina L. Byrne, Dana Broach

International Symposium on Aviation Psychology - 2015

In this study, we investigated the utility and fairness of using the Air Traffic Selection and Training (AT-SAT) test battery to place Air Traffic Control Specialist (ATCS) applicants into terminal or en route facilities. While results of statistical analyses indicated that AT-SAT could be considered a valid tool for use in placement, based on technical considerations only, it was concluded that it should not be used in that way due to lack of utility and potential for adverse impact. If the FAA were to use AT-SAT for placement, the risk of additional adverse impact and pay disparities should be evaluated …

Identifying Mental Models Of Search In A Simulated Flight Task Using A Pathmapping Approach, Brandon S. Perelman, Shane T. Mueller

International Symposium on Aviation Psychology - 2015

Aerial assets are often used for missions such as intelligence, surveillance, target acquisition and reconnaissance. The pilot’s search decisions reflect a mental model for the search space, including characteristics such as target prioritization, distance-reward evaluations, and path optimization cri-teria. To investigate differences in these mental models, we examined 23 participants’ paths flown in a synthetic task environment in which they piloted a simulated aircraft to search for targets rep-resenting missing persons. Determining similarity among flight paths is a challenge. To accom-plish this, we used a new tool (Pathmapping, a package in the R statistical computing language; Mueller, Perelman, & Veinott, …

Faa Training Assessment Of On-The-Job Training, Darendia Mccauley

International Symposium on Aviation Psychology - 2015

The field training administered to air traffic controllers is provided by instructors who are also controllers but have undergone training to become on-the-job training instructors (OJTIs). The training of these field OJTIs is under revision based on a training needs assessment conducted in 2011. Controllers who were not successful in training at their first facility can be reassigned to another facility, where they receive field training specific to that facility. The controllers who did not succeed in training initially and requested reassignment may have a useful perspective on the training they received. This perspective may aid in revising the training …

Eeg Data Analysis Using Artifact Separation, Chelsey Credlebaugh, Matthew Middendorf, Michael Hoepf, Scott Galster

International Symposium on Aviation Psychology - 2015

It has been postulated that physiological measures can be a positive indicator of mental workload. One such measure is the electroencephalogram (EEG). It is well known that the EEG signal is easily affected by artifacts. One prominent source of artifacts is eye activity, including blinks and saccades. These contaminates coincide directly with EEG signals, making it difficult to obtain artifact-free data. This paper discusses a methodology that performs artifact separation at the data analysis stage. This technique was used to analyze data from a recent experiment. Workload was manipulated by varying the difficulty of the primary task while responding to …

Enroute Atc Industry Perceptions Of Simulation Fidelity, Colin Dow, Jonathan Histon

International Symposium on Aviation Psychology - 2015

Enroute air traffic control (ATC) relies heavily on simulation in training, research, and concept development applications. However, it has little domain-specific research on the effects of simulation fidelity and lacks a standardized definition of simulation fidelity in the literature. A survey of ATC industry professionals shows that simulation fidelity is not perceived to be well defined for the domain of enroute ATC, regardless of respondent nationality, experience, use of simulation or gender. Parts of the operational environment that survey respondents felt were important components in a definition of simulation fidelity are reported; Communications is the most important component regardless of …

Pilots’ Willingness To Report Aviation Incidents, Andreas Haslbeck, Carsten Schmidt-Moll, Ekkehart Schubert

International Symposium on Aviation Psychology - 2015

This paper reports results from a survey-based study among eighty-six airline pilots investigating their willingness to report safety-relevant events and incidents. Pilots have been asked to report how many events they have experienced in thirty-five different contextual areas and how often they have reported these cases. Thus, underreporting rates, respectively dark figures, were calculated and listed. These results and the willingness to report are discussed within an aviation operation’s background. Most of these surveyed underreporting rates are very high, which means a substantial source of uncertainty in airlines’ safety reporting databases, and thus for airlines’ safety management systems.

Haptic Guidance, Interaction Between The Guidance Model And Tuning, M.M. (Rene) Van Paassen, Rolf P. Boink, David A. Abbink, Mark Mulder, Max Mulder

International Symposium on Aviation Psychology - 2015

A haptic interface, also called haptic display, is a system that informs and aids a human operator by forces on the control device (stick, steering wheel or other). These interfaces are being explored for many fields, e.g., for UAV control, (tele-)robotics, automotive control and flying. The force feedback helps in control tasks and increases the operator’s awareness. Proper design of such interfaces promotes “shared control”, where an autonomous agent and the human operator can jointly exercise control on a dynamic system. The human’s flexibility and adaptivity of his neuromuscular system offers ways to override the haptic support, should this be …

A Regression Of Consumer Atttitudes Toward Airport Water Reuse, Ismael Cremer, Stephen Rice, Scott R. Winter

International Symposium on Aviation Psychology - 2015

Recent studies have focused on characterizing and understanding the public’s perceptions of risk with respect to general reuse projects (Baggett, Jefferson & Jefferson 2005; Hurlimann 2011; Toze, 2005). These studies have shown varying attitudes toward water reuse and are necessary to assess the public’s risk perception and acceptance of water reuse before implementing it. To date, no studies have examined whether certain variables affect people’s attitudes toward the water reuse concepts at airports. Four hundred and four participants from India and the United States participated in a study wherein various socio-economic were collected along with their attitude scores toward water …

International Symposium on Aviation Psychology - 2015

A key capability envisioned for the future air transportation system is the concept of equivalent visual operations (EVO). EVO is the capability to achieve the safety of current-day Visual Flight Rules (VFR) operations and maintain the operational tempos of VFR irrespective of the weather and visibility conditions. Enhanced Flight Vision Systems (EFVS) offer a path to achieve EVO. NASA has successfully tested EFVS for commercial flight operations that has helped establish the technical merits of EFVS, without reliance on natural vision, to runways without category II/III ground-based navigation and lighting requirements. The research has tested EFVS for operations with both …

Perspectives Of Unsuccessful Air Traffic Control Specialists, Linda G. Pierce, Cristina L. Byrne

International Symposium on Aviation Psychology - 2015

Approximately one-quarter of air traffic controller trainees fail field training at their first facility assignment. In some cases, those who fail the training qualifications at their first air traffic control facility assignment are allowed to transfer to a less complex facility. We surveyed a sample of these controllers to identify their perceptions of work-related and external factors that contributed to their failure and subsequent request for reassignment. For example, although these controllers were selected to work at their first facility, in part, based on their aptitude for the job, some said they simply could not do the work at the …
