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

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

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.

Investigating Pilot’S Decision Making When Facing An Unstabilized Approach: An Eye-Tracking Study, Maxime Reynal, Frank Rister, Sebastien Scannella, Christopher Wickens, Frederic Hehais

International Symposium on Aviation Psychology - 2017

Unstabilized approach has been identified to be a major causal factor of approach-and-landing accidents (e.g. off-runway touchdowns, hard landing, tail-strikes, etc).We conducted an experimentin order to analyze pilots’ performance during such approaches. Ten type-rated, commercial pilots flew each in a B737 full-flight simulator during anunstabilizedapproach at Hamburg airport. The Pilot Flyings’ (PF) eye gazes were collected. The results revealed that half of the pilots persisted in an erroneous landing decision. These latter pilots had higher dwell time on the attitude indicator/flight director whereas the group of pilots who perfomed the go-around exhibited more fixations on the navigation display prior to …

Alerts On The Nextgen Flight Deck, Angelia Sebok, Christopher D. Wickens, Brett Walters, Karl Fennell

International Symposium on Aviation Psychology - 2017

The future generation of cockpit may substantially change the nature of displays, automation, and their implications for alerting systems. Flight deck automation and information systems imposed by NextGen will create system states that may need to be alerted. New concepts of providing continuous flight information can benefit pilot awareness. Ecological interface displayskeep the operator aware of the system status and constraints, informing the pilot of emerging concerns before an alert is triggered. Continuous auditory and tactile displays support pilot awareness without requiring focused operatorattention. Both approaches improve awareness of system state, but suffer poor operator acceptance. Automation can support pilots …

Effects Of Simulator Training For Unmanned Aerial Systems In Undergraduate Education, William Weldon, Dr. Brian Kozak

International Symposium on Aviation Psychology - 2017

Unmanned aerial systems (UAS) are being added to the national airspace (NAS) in very large numbers. Many universities have seen this demand for UAS operators and begun to create programs in order to train undergraduate students in their use. The UAS industry currently lacks adequatetraining requirements for beginning operators. This fact makes university training important, because universities are oneof the few places that offer structured training. While the UAS industry in the US is in its infancy it is possible to draw parallelismsthe training history of manned flight in order to avoid pitfalls and offer training in the most efficient …

Fatiguing The Force: Using Operational Data To Improve The United States Air Force’S Mission Effectiveness Model, Kelly M. Amaddio, Jennifer P. Howland

International Symposium on Aviation Psychology - 2017

Air mobility pilots routinely fly multiple missions spanning several time zones, thereby disrupting their circadian rhythm. As a result, they consistently operate at a sub-optimal performance level. After several fatigue-related accidents, the Air Mobility Command (AMC) Safety Office incorporated the Sleep, Activity, Fatigue, and Task Effectiveness (SAFTE) model into its Aviation Operational Risk Management (AvORM) program to inform aircrew members of their fatigue levels during critical phases of flight. Further analysis indicated that aircrew members experience higher fatigue levels than predicted, which directly reduces flight safety. This study seeks to improve the underlying assumptions within the sleep model to more …

An Eeg Data Investigation Using Only Artifacts, Chelsey Credlebaugh, Paul Middendorf, Matt Middendorf, Scott Galster

International Symposium on Aviation Psychology - 2017

For decades, it has been reportedthat theelectroencephalogram (EEG) isa positive indicator of mental workload. However, EEG signals are easily affected by artifacts.Anartifact mediation approach, called artifact separation, was developed to enable the consumer of the EEG data to decide how to handle artifacts. The current investigation uses onlydata contaminated by artifacts and discards the artifact free data.This was doneto solve a problem associated with data collection.Specifically, in an experiment, EEGelectrodeleadsforT3 and Fzwere swapped where they were connected to the signal acquisition hardware. To facilitate analysis of the data, it was essential to determine whenthe swap occurred. This was accomplished using …

Cognitive Constraints For Automation On Flight Testing, Diogo Silva Castilho

International Symposium on Aviation Psychology - 2017

The first flight of a new aircraft is still a dangerous event. Despite all simulations and software predictions, test pilots face many unknowns when a prototype leaves the ground for the first time. The cultural celebration of first flights masks the concerns of many stakeholders about the technical challenges of the new equipment. The pilot extensively prepares to react properly to unexpected situations and often bring a new story to tell, but in a time whenremotely piloted and autonomous aircraft fly every day, the question about how to use their technologies to save a test pilot life arises. This study …

The Opioid Epidemic In The United States With A Focus On Ohio, Timothy A. Netters Jr.

Master of Public Health Program Student Publications

The rate of deaths due to opioid drug overdoses has increased substantially in the 21st-century United States and shows no signs of slowing down. Goleman (1987) stated that opioid drugs are not inherently dangerous when used for their specified purpose of relief of moderate to severe acute pain. However, when they are abused, mixed with other drugs, or their stronger counterparts, used for chronic pain or are used without understanding of their increased strength the effects can be devastating. Ohio is unfortunately no stranger to the problem of opiate abuse and overdose. Counties throughout Ohio have had to add additional …

Crew State Monitoring And Line-Oriented Flight Training For Attention Management, Chad Stephens, Lawrence Prinzel, Angela Harrivel, Ray Comstock, Nijo Abraham, Alan Pope, James Wilkerson, Daniel Kiggins

International Symposium on Aviation Psychology - 2017

Loss of control –inflight (LOC-I) has historically represented the largest category of commercial aviation fatal accidents. A review of worldwide transport airplane accidents (2001-2010) indicated that loss of airplane state awareness (ASA) was responsible for the majority of the LOC-I fatality rate. The Commercial Aviation Safety Team (CAST) ASA study identified12 major themes that were indicated across the ASA accident and incident events. One of the themes was crew distractionorineffective attention management, which was found to be involved in all 18 events including flight crew channelized attention, startle/surprise, diverted attention, and/or confirmation bias. Safety Enhancement(SE)-211, “Training for Attention Management” was …

These countries experienced a major problem with the number of reported AIs. Interview transcripts were analysed using thematic analysis. The success of this study is attributed to the carefully design of both the questions of the interview and the sample that comprises the diverse general aviation sector.The newly found contributory factorsare associated with a pilot’s performance as well as airspace design …

Synthetic Vision System Commercial Aircraft Flight Deck Display Technologies For Unusual Attitude Recovery, Lawrence (Lance) J. Prinzel Iii, Kyle E. Ellis, Jarvis (Trey) J. Arthur, Stephanie N. Nicholas, Captain Daniel Kiggins

International Symposium on Aviation Psychology - 2017

A Commercial Aviation Safety Team (CAST) study of 18 worldwide loss-of-control accidents and incidents determined that the lack of external visual references was associated with aflight crew’s loss of attitude awareness or energy state awareness in 17 of these events. Therefore, CAST recommended development and implementation of virtual day-Visual Meteorological Condition (VMC)display systems, such as synthetic vision systems, whichcan promoteflight crew attitude awareness similar to a day-VMC environment. This paper describes the results of a high-fidelity, large transport aircraft simulation experimentthatevaluatedvirtual day-VMC displays and a “background attitude indicator” concept as an aid to pilots in recovery from unusual attitudes. Twelve …
