Task Complexity And Time Pressure Affect Air Traffic Controller’S Performance And Workload, Qianru Yang, Andrew R. Dattel
Task Complexity And Time Pressure Affect Air Traffic Controller’S Performance And Workload, Qianru Yang, Andrew R. Dattel
International Symposium on Aviation Psychology - 2017
The purpose of this study was to investigate the effects of task complexity (TC) and time pressure (TP) on air traffic controller’s (ATC) performance and mental workload. Sixteen students enrolled in an aviation college completed four scenarios which were a subset of the ATCPrep software for the AT-SAT. Fifteen performance variables were measured (e.g., conflict resolution). Additionally, NASA-TLX was used to test participants’ mental workload. As expected, for most of the performance variables, high TC andhigh TP resulted in the lowest participant performance. For the three performance variables, TP had a differential effect on TC. Participants experienced the greatest mental …

International Symposium on Aviation Psychology - 2017
We evaluate a newly developed symbology that provides the pilot predicted and advisory airspeed information. This information is not only based on the current state of the aircraft, but also takes into account the wind field ahead of the aircraft measured by an onboard LIDAR system. Airline pilots flew landing approaches in wind shear scenarios that demanded careful consideration of whether to land on go-aroundin JAXA's full flight simulator. We obtained both subjective evaluations and objective data including flight performance, eye recoder data, electrocardiogram (ECG), electroencephalogram (EEG), and performance on a simple visual secondary task. The pilots considered all newly …
Flight Experience And Mental Representations Of Space, Mikayla Keller, Jennifer E. Sutton
Flight Experience And Mental Representations Of Space, Mikayla Keller, Jennifer E. Sutton
International Symposium on Aviation Psychology - 2017
Spatial skills are critical for flight safety. The current study investigatedwhetherincreased flight experience as a pilotwas associated with improved spatial skills, and in particular, theability to form a mental representation of a novel virtual environment.Pilotscompleted small-scalespatial ability tasks, travelled alongfour routes in a virtual environment, and then completed two tests that assessed memory for the locations of landmarks in the environment. Pilots with more flight experience did not have more accurate mental representations of the environment than individuals with less flight experience. Increasedflyingexperience was, however, linked to better performance on a perspective-taking test. Perspective taking has been proposed as central …
Investigating Facial Electromyography As An Indicator Of Cognitive Workload, Jonathan Mead, Matt Middendorf, Christina Gruenwald, Chelsey Credlebaugh, Scott Galster
Investigating Facial Electromyography As An Indicator Of Cognitive Workload, Jonathan Mead, Matt Middendorf, Christina Gruenwald, Chelsey Credlebaugh, Scott Galster
International Symposium on Aviation Psychology - 2017
Facial electromyography (fEMG) is an electromyographic measurement technique that has primarily been used as a tool for measuring affect, but previous experiments suggest that it also has the potential to help quantify cognitiveworkload. In the current study, two task-irrelevant facial muscles, corrugator supercilli and lateral frontalis, were monitored in real-time to determine whether they were sensitive to workload changes in a remotely piloted aircraft (RPA) task environment. Real-time signal processing techniques were applied to derive the median amplitude and zero-crossing rate from windowed fEMG data. Statistical analysis of these features determined that both muscles were sensitive to variations in specific …

Advancement In Pedagogical Foundations: Developing Language Proficiency For Student Success, Stacey L. Mcintire, Juan R. Merkt, Jacqueline R. Luedtke, Timothy B. Holt, Brent D. Bowen, Hunter Watson
International Symposium on Aviation Psychology - 2017
Interruptions in flight training and a corresponding increase in costs appear to be prevalent among universities with aviation training programs. Students in these programs have to manage both demanding academics and flight training. Additionally, international students, for whom English is not their primary language, have the added disadvantage of learning complex aviation concepts in English. In order to maximize retention in collegiate flight programs, an experimental aviation English course has been designed to helpfrontload aviation vocabulary and take a proactive approach to teaching language skills that are essential in flight training. This as a case study model includes the learning …
Aviation English Intelligibility, Julia Trippe, Eric Pederson
Aviation English Intelligibility, Julia Trippe, Eric Pederson
International Symposium on Aviation Psychology - 2017
Aviation English (AE) is the “primary dialect” of international aviation. Demonstrably, AE and Conversational English (CE) are distinct varieties of English. Pastresearch shows that AE is spoken more rapidly, with less inflectional variation and differentrhythm than CE. Differences are strong enough that AE and CEmaynot be mutually intelligible. However, flight students are not trained in AE production and perception prior to flight training.This study examines the intelligibility relationship between AE and CE by comparing native English speaking non-pilots andnative English speaking pilots responding to actual air traffic controller transmissions. A difference between these groups was predicted, given theircomparative AE familiarity. …

International Symposium on Aviation Psychology - 2017
Airborne surveillance operations present challenging environments for tactical operators and for the technologies that support these activities. Information from multiple sources is currently presented on 2D displays, but the influx of data hasmade it difficult to represent this informationusing traditional technologies. Recent innovations in VR have laid the groundwork for a promising solution to this problem by allowing users to immerse themselves in 3D representations of the real worldwith embodied tracking capabilities. The present research examined thefeasibility of transitioning two common tactical operator tasks from a 2D to a 3D/VR user interface. Naive participants searchedfor targets amongst a set of …

Does The Projected-Hand Illusion Help In Teleoperation?, Lloyd Wajon, M.M. (René) Van Paassen, David A. Abbink, Erwin Boer, Max Mulder
International Symposium on Aviation Psychology - 2017
A body illusion, commonly known in the form of the “Rubber Hand Illusion”, is an illusion wherein visual inputs on an inanimate object and simultaneous tactile inputs on a part of the body lead to a situation where the inanimate object is identified as the body part. This study investigated the possibility of inducing a body illusion during a teleoperated reaching task, to see if this leads toincreased telepresence and improved accuracy. Three conditions were presented in random order; the Direct Control (DC) condition, where the participant’s hand is shown on the screen, the Projected Hand Illusion (PHI) condition, showing …
A Pedagogical Approach To Teach Aviation Students How To Conduct Situation Awareness Research, Andrew R. Dattel, Andrey Babin, Tianhua Li, Ziyi Dong, Stephanie G. Fussell, Qianru Yang
A Pedagogical Approach To Teach Aviation Students How To Conduct Situation Awareness Research, Andrew R. Dattel, Andrey Babin, Tianhua Li, Ziyi Dong, Stephanie G. Fussell, Qianru Yang
International Symposium on Aviation Psychology - 2017
Situation awareness (SA) has been investigated in the aviation industry for decades and recently has become more prominent in other industries. For example, healthcare has experienced tremendous growth in SA research and training. Despite agreement among researchers that SA is important for performance and safety in complex domains, less agreement exists for defining and measuring SA. Certain industries (e.g., aviation, healthcare, process control operations) often have specific methods on how to approach SA. These approaches of introducing employees and students to SA in a specific context may inadvertently limit their full appreciation and understanding of this construct.

Pegasas: Weather Technology In The Cockpit, Ian Johnson, Geoff Whitehurst, Vladimir N. Risukhin, Lori J. Brown, William Rantz, Thomas K. Ferris, Trey Roady, Carolina Rodriguez-Paras, Kathryn Tippey, Mel J. Futrell
International Symposium on Aviation Psychology - 2017
Research showsthat a high percentage of weather-related General Aviation (GA) accidents can be attributed to pilots flying into Instrument Meteorological Conditions (IMC) without experience or appropriate certifications to safely operate beyond Visual Flight Rules (VFR). To makesafety-critical decisions, pilots oftenuse weather indication delivered on screens of portable electronic devices. This information often is obsolete with a latency up to20 minutes. Web-based experiential education modules, using a flight simulation system for demonstration of this weather indication latency, can potentially mitigate this problem.Modules will be designed to provide pilots with the ability to “experience” different weather phenomenaand will include tools to improve …

Role Of Early Flying Performance In Pilot Training Tracks, Rana Ihara, Yumi Shibata, Yuko Aiba, Takenori Nomiyama, Asao Kobayashi
International Symposium on Aviation Psychology - 2017
Early flying skills have been reported to strongly influence future flying skills. Few published studies have evaluated the comprehensive relationship among all flying training skills. This study evaluated three causal path models for flying skills that influenced flying performance rated by instructor pilots in five training phases. A covariance structure analysis showed that asequential model with a connection between the first and last phases was optimumfor representing flying training performance and skills. The flying skill acquired in the first training phase in a primary propeller aircraft influenced the last training skill in a fighter jet directly as well as indirectly. …
Predicting Air Traffic Control Student Success And Improving Placement Through Skill Aptitude Testing, Kerry Huston, Keith Baldwin, Susan Schultheis
Predicting Air Traffic Control Student Success And Improving Placement Through Skill Aptitude Testing, Kerry Huston, Keith Baldwin, Susan Schultheis
International Symposium on Aviation Psychology - 2017
In orderto improve Air Traffic Control (ATC) training efficiency and reduce the risk of student failure, the FAA needstools that can predict student success and inform student placement in training. By considering student aptitude, the FAA could reduce training costs by reducing student failure rates and transfers between facilities.In order to explore the benefits of early aptitude assessment, The MITRE Corporation (MITRE) created a prototype Radar Vectoring Aptitude Test designed to be administered to students before they begin their training to assess their aptitude for the skill of radar vectoring. The FAA office of Safety and Technical Training (AJI-2) in …
Experimental Evaluation Of A Scalable Autonomy Concept For Cognitive Agents Aboard Reconnaissance Uavs, Georg Rudnick, Axel Schulte
Experimental Evaluation Of A Scalable Autonomy Concept For Cognitive Agents Aboard Reconnaissance Uavs, Georg Rudnick, Axel Schulte
International Symposium on Aviation Psychology - 2017
The concept of scalable autonomy with a guided access to lower automation levelsallows human UAV pilots to select the level of autonomy and enables the onboard automation to understand the pilot’s intent and offer support. To evaluate this concept, we conducted flightand simulationexperiments with German military personnel performing reconnaissance missions with a small UAV. We compared threeconfigurations. The high autonomy configuration completely prevents access to low-level functions. The naive approach configuration allows unrestricted access to all lower-level functions. The guided access configuration restricts access by forcing the pilot to communicate his intent first by entering mission tasks. As dependent variables, …
Evaluating Spatial-Auditory Symbology For Improved Performance In Low-Fidelity Spatial Audio Displays, Griffin D. Romigh, Jose Villa, Jason Ayers
Evaluating Spatial-Auditory Symbology For Improved Performance In Low-Fidelity Spatial Audio Displays, Griffin D. Romigh, Jose Villa, Jason Ayers
International Symposium on Aviation Psychology - 2017
For decades, spatial auditory displays have been considered to be a promising technology to help fight pilot disorientation and loss of SA. Inherently heads-up, these displays can provide time-critical spatial information to pilots about navigational targets, air and runway traffic, wingman location, and even the attitude of one’s aircraft without placing additional demands on the already over-tasked visual system. Unfortunately, currently-fielded auditory displays often suffer from poor spatial fidelity, particularly in elevation, due to their use of a one-size-fits-all (i.e., non-personalized) head-related transfer function (HRTF), the set offilters responsible for creating the spatial impression. The current study investigated the utility …

Engineering For Humans: A New Extension To Systems Theoretic Process Analysis, Megan France, John Thomas
International Symposium on Aviation Psychology - 2017
Systems Theoretic Process Analysis (STPA) is a new hazard analysis method developed at MIT to address a broad range of accident causal factors including dysfunctional interactions among components, design flaws, and requirements problems. This paper presentsa new extension for analyzing human interactions with automation and understanding why unsafe behaviors may appear appropriate in the operational context. The extension is demonstrated by applying it to pilot control of aircraft pitch control during stall recoveryusing scenarios from theAir France 447 accident

An Interdisciplinary Approach To Evaluating U.S. Army Aviation Training, Martin S. Goodwin, Lauren Reinerman-Jones, Brian F. Goldiez, Robert A. Crapanzano
International Symposium on Aviation Psychology - 2017
The U.S. Army is seeking to update and expand its use of simulation-based aviation trainingto address operational and fiscal concerns that are driving the need for more efficient training solutions.This has created a needto evaluate whether lower-cost, game-based simulations may potentially augment higher-cost, traditional simulation-based trainingfor specific aviation training tasks.However, current approaches to Training Effectiveness Evaluation (TEE) do not address the complete range of factors to adequately evaluate today’s increasingly sophisticated simulation training environments. Leveraging recent research and drawing from the tools and techniques of human performance assessment, instructional science, and phenomenology, an interdisciplinary approach to performing TEEs is introduced …
Increasing Acceptance Of Haptic Feedback In Uav Teleoperations By Visualizing Force Fields, Victor Ho, Clark Borst, Rene Van Paassen, Max Mulder
Increasing Acceptance Of Haptic Feedback In Uav Teleoperations By Visualizing Force Fields, Victor Ho, Clark Borst, Rene Van Paassen, Max Mulder
International Symposium on Aviation Psychology - 2017
In tele-operating an UAV, human operators fully rely on cameras to control thevehicle from a distance. To increase operator situation awareness and reduce workload, haptic feedback on the control stick has been developed which acts as an automatic collision avoidance system. A virtual force field surrounding the moving vehicle interacts with obstacles surrounding it,yielding repulsive forces on the stick that leadthe vehicle away from them. Albeit successful in significantly reducing the number of collisions,thehaptic interfacereceivedlow user acceptance ratings.Operators do not always fully understand the collision avoidance automation intentions, and they experience the haptic forces as intrusive. This paper discusses thedevelopment …

Human Decision Making And Threat-Awareness Response During Emergency Aircraft Evacuations, Sarah Hubbard, Tim Ropp
International Symposium on Aviation Psychology - 2017
Aircraft emergencies requiring evacuation present unique safety challenges to both crew and passengers due to theconfined space and the speed at which fire, extreme heatand smoke propagate. In thisscenario, where a one or two second delay can literally determine survivability, rapid evacuation is paramount. Although evacuation capability is demonstrated through requiredand controlleddrillsfor aircraft certification, during a real emergencyhuman factorsaffect passenger decision making, in some cases resulting in the decisionto retrieve personal items during actual emergency evacuations. This may pose a significant threat to post-accident survivability. This research evaluates evacuation decision making and the associated impact on passenger exit flow, during …

International Symposium on Aviation Psychology - 2017
Today, security officers at military and civilian installations are often required to track people and vehicles (targets) movingin a remote space using a distributed array of stationary security cameras. A pervasive tracking challenge is maintaining view of the target as it moves through the restricted fields of view of different cameras. The current research explores how different displaydesigns indicating camera fields of viewimpact the operator’s situation awareness of the next best camera to continue viewing a moving target. Three different interface displays(Full North-Up Map, Peripheral Display, and Track-Up Mini-Map) wereevaluated over four experimental conditions.While having all display types available was …

International Symposium on Aviation Psychology - 2017
The emerging wearable human performance monitoring technologies can help evaluate the cognitive status and capacities of the crew in the cockpit as well as those operating ground control stations. Traditionally the use of behavioral measures and subjective metrics has been used to address cognitive factors associated with pilots or operators of safety critical systems. However, the advance in wearable physiologytechnologies could provide additional performance metrics directly driven from brain based measures, potentially validating subjective assessments and ultimately bringing us closer towardsmaintaining safe and effective performance. Furthermore, these techniques may also aidthe design and evaluation of new technologies that are being …

Toward Identifying Risk In Operational Performance Of Atc Procedures, Paul Krois, Julia Pounds
International Symposium on Aviation Psychology - 2017
Managing operationalperformance to reduce risk in the execution of air traffic control (ATC) procedures depends on understanding human performance in relation to patterns established in procedures. Procedures specify performance requirements meant to minimize unintended variation that is outside expected performance criteria and tolerances.We define human performance risk as unintended variation outside theenvelope of applicable procedures.

The Effect Of Surprise On Upset Recovery Performance, Annemarie Landman, Eric L. Groen, M.M. (René) Van Paassen, Adelbert W. Bronkhorst, Max Mulder
International Symposium on Aviation Psychology - 2017
Introducing the element of surprise is one of the main challenges in simulator training of in-flight emergencies. In this simulator study, we investigated the differences in performance betweenpredictable and surprising circumstances, in order to obtaininsight into the transferof training between predictable training settings and surprising circumstances in operational practice. This was done bytestingtwenty airline pilots who recovered froman aerodynamic stall in two conditions: one anticipationcondition and one surprise condition. All pilots practiced beforehand using predictable, or non-surprising scenarios. The results show that pilots had significantly more difficulties in adhering to components of the FAA-commissioned recovery template in the surprise condition …

Is Rho The Key To Hazardous Weather Avoidance?, William R. Knecht
International Symposium on Aviation Psychology - 2017
Current in-cockpit looping Next-Generation Radar (NEXRAD) is inadequate to maintain safe (20 nm) aircraft separation from heavy weather (> 40 dBZ reflectivity). This assertion issupported by mathematical information analysis and an empirical study (Knecht, 2016), as well as numerous previous empirical studies. The current work revisitsthe ecological analysis by examining the putative affordance (rho) specifying when weather-avoidance maneuver should begin, as suggested by General Tau Theory (Lee, 2009).With“gapdefined as the distance between the on-screen aircraft icon and the weather hazard, is specified by the ratio ((dg/dt)/g)(t), the instantaneous gap contraction rate divided by the instantaneous gap size. In current …

A Case Study Using The Human Factors Analysis And Classification System Framework, Flavio A.C. Mendonca Ph.D., Chenyu Huang Ph.D., Julius Keller Ph.D.
International Symposium on Aviation Psychology - 2017
Aircraft accidents are generally the end result of a number of latent conditions arising in the organizational and managerial sectors. These conditions frequently permit or even motivatethe unsafe acts by the flight crew. The Human Factors Analysis and ClassificationSystem (HFACS) is a system safety tool for the investigation and analysis of underlying human causal factors in aircraft accidents. Using the HFACS framework, four researchers classified the human factors identified by the Brazilian Aeronautical AccidentsInvestigation and Prevention Center (CENIPA) during the investigation of a mishap(PR-AFA) that happened in Brazil in 2014. CENIPA argued that errors and violations by both pilots contributed …

Usaf Spatial Disorientation Prevention: A Meta-Analytical Human Systems Integration Perspective, Patrick O'Neil, Booz Allen Hamilton, Michael Miller
International Symposium on Aviation Psychology - 2017
Human Systems Integration involvesthe systematic consideration of tradeoffs in system structure or behavior, which affect sevenhuman-centered domains to optimize total system performance and life cycle cost.All too often, HSI is overlooked or poorly practiced, despite the specific directive within DoDI 5000.02 for program managers to plan for and conduct HSI. In the worst of cases, poor consideration of human capabilitiesandlimitations leads to errors, mishaps, and death or serious injury. One such human limitation in aviation is the inability of the pilot to maintain proper spatial orientationduring flight,asmismatches between the stimuli present during flight create an erroneous perception of aircraft attitude …
Understanding Pilots’ Explanations Of Automation Surprises, Robert Mauro, Loukia Loukopoulou, Julia Trippe
Understanding Pilots’ Explanations Of Automation Surprises, Robert Mauro, Loukia Loukopoulou, Julia Trippe
International Symposium on Aviation Psychology - 2017
Automation surprise may result from inadequate or mistaken “mental models” of the automation (Sarter and Woods, 1995). To study pilots’ mental models of their automation, 202 airline pilots were asked to explain five different events involving unexpected behaviors of aircraft automation. Pilots’ abilities to correctly explain the behavior of the automation differed systematically across the scenarios. The number of complete and correct responses varied from 19% to 86%, depending on the scenario. As the complexity of the automation increased, understanding decreased. Performance on the scenarios was not related to flight experience, automation experience, or source of automation training. But pilots’ …
Operationalizing The Definition Of Risk As Variability, Julia Pounds, Paul Krois, Barry C. Davis, Melissa Wishy
Operationalizing The Definition Of Risk As Variability, Julia Pounds, Paul Krois, Barry C. Davis, Melissa Wishy
International Symposium on Aviation Psychology - 2017
Maintaining safety requires acknowledgingrisk. However, one’s definition of risk can depend on whether the word is being used in everyday conversation or by safety practitioners or by domain experts. Not having a commonly agreed-upon definition poses problems for those charged with identifying, reducing, and communicating about risk. In an effort to standardize the definition, the International Organization for Standardization defined risk simply as the effect of uncertainty on objectives. Still, this general definition lacks enough specificity to describe uncertainty’s positive or negative effects. Relevant information can reduce uncertainty’s potential effects if it’s not ambiguous, unreliable, incomplete, or unavailable.
