The Effect Of Asynchronous Data On Pilot-Controller Communication In A Dynamic Environment With Subject-Matter Experts, Samuel Lien, Jonathan Histon

International Symposium on Aviation Psychology - 2015

Integrating Unmanned Aerial System (UAS) into controlled airspace may introduce communication challenges if there are time delays associated with the distribution of a common surveillance source of those UAS. Termed “information asynchrony” by Yuan et al (2012), an earlier, static image study showed large time delays had an observable impact on controller-pilot communication, but the effect was not present for time delays of less than 1 minute. A follow-up study is being conducted using an online ATC-flight simulator with professional pilots and controllers as participants. Effects on communication are being analyzed objectively through measurable characteristics of communication breakdown, and subjectively …

‘We Need Priority Please’ Mitigated Speech In The Crash Of Avianca Flight 052, Simon Cookson

International Symposium on Aviation Psychology - 2015

On 25 January 1990, Avianca Flight 052 was flying from Columbia to the United States when it crashed after a missed approach to JFK Airport in New York. The direct cause of the accident was fuel exhaustion but the NTSB investigation identified multiple causal factors. The Avianca captain, who was flying the aircraft, repeatedly instructed the first officer to notify ATC about the fuel emergency. The first officer, however, did not use the word ‘emergency’ but instead requested ‘priority’ and told ATC that the airplane was ‘running out of fuel’. Why did the first officer mitigate the captain’s instructions? This …

Understanding Automation Surprise: Analysis Of Asrs Reports, Julia Trippe, Robert Mauro

International Symposium on Aviation Psychology - 2015

Pilots are frequently surprised by aircraft automation. These include cases in which the automation: 1) produces alerts to anomalies, 2) commands unexpected control manipulations (that may result in flight path deviations), or 3) simply disconnects. Aviation Safety Reporting System (ASRS) reports in which pilots indicated that automation produced unexpected actions were analyzed. Three general conclusions were drawn. First, many factors precipitate automation surprises. These include problems in: the auto-flight system and associated displays and interfaces, other aircraft sensors and systems, and interactions with weather and ATC. Second, inappropriate pilot actions are involved in a large proportion of these events. Third, …

Visualization Methods For Communicating Unmanned Vehicle Plan Status, Kyle J. Behymer, Heath A. Ruff, Elizabeth M. Mersch, Gloria L. Calhoun, Sarah E. Spriggs

International Symposium on Aviation Psychology - 2015

In order to facilitate a single operator controlling multiple unmanned vehicles, numerous autonomous support tools are being considered. One such candidate tool monitors the situation and alerts the operator when a deviation from the vehicle’s plan has occurred. The goal of this research was to develop an effective visualization method for conveying plan deviations. Two interface formats were developed based on a review of the literature: a pie chart and a bar chart. Each format allows an operator to compare values for parameters that have different units, value ranges, and relative priority. Twelve participants were tested using a 2 (chart …

Design And Evaluation Of A Haptic Display For Flight Envelope Protection Systems, J. Ellerbroek, M.J.M. Rodriguez Y Martin, M.M. Van Paassen, M. Mulder

International Symposium on Aviation Psychology - 2015

This paper describes the design and initial evaluation of a haptic display that is aimed to complement a `hard’ flight envelope protection system. The evaluation mainly focused on usability of the presented haptic cues, and on the handling qualities of the stick with active feedback. Results are presented for two evaluations, concerning stall protection feedback and load factor protection feedback respectively. They show that while subjects are positive about the added information cue, and are able to correctly identify limiting actions, they are not consistently able to identify changes in the aircraft’s condition.

Detecting Structure In Activity Sequences: Exploring The Hot Hand Phenomenon, Taleri Hammack, John Flach, Joseph Houpt

International Symposium on Aviation Psychology - 2015

Can humans discriminate whether strings of events (e.g., shooting success in basketball) were generated by a random or constrained process (e.g., hot and cold streaks)? Conventional wisdom suggests that humans are not good at this discrimination. For example, Kahneman (2011) writes that “the hot hand is entirely in the eye of the beholders, who are consistently too quick to perceive order and causality in randomness. The hot hand is a massive and widespread cognitive illusion” (p. 117). Following from Cooper, Hammack, Lemasters, and Flach (2014), a series of Monte Carlo simulations and empirical experiments examined the abilities of both humans …

Airframe Parachute Knowledge And Deployment Scenarios: A Collegiate Perspective, Scott R. Winter, Robert C. Geske, Stephen Rice, Richard O. Fanjoy, Lauren Sperlak

International Symposium on Aviation Psychology - 2015

As airframe parachutes in general aviation aircraft become more popular, training is essential in fostering a willingness to use the system in the appropriate situation. Aviation decision-making literature suggests that individuals make choices based on experience and pattern matching, such as emergency situations and airframe parachute deployment scenarios. This led the researchers to investigate the knowledge and perspectives of collegiate pilots who train in aircraft equipped with airframe parachutes. Participants completed a surveyfocused on airframe parachute knowledge and scenario-based examples. Training experts were used to validate the parachute deployment scenarios used in the instrument. Responses indicate that pilots find aircraft …

The Federal Aviation Administration’s Human Factors Research and Engineering Division has strengthened the presence of human factors activities in NextGen products in the Human Systems Integration (HSI) and other Roadmaps. This paper will present the HSI Roadmap and explore NextGen human factors integration opportunities in tower operations. Opportunities have …

Consumer Trust Ratings After An Airline Accident: An Affective Perspective, Scott R. Winter, Stephen Rice, Ismael Cremer, Rian Mehta

International Symposium on Aviation Psychology - 2015

Fortunately airline accidents are rare; however when one occurs it usually results in widespread media attention. The purpose of this study was to examine how consumers’ trust ratings were impacted when one airline suffered an accident. The findings indicate that System Wide Trust (SWT) theory applies resulting in a trust reduction for all airlines, not just the accident airline. Affect was shown to act as a mediator in only three of the cases, which suggest that consumer’s responses may not be strongly influenced by emotions. Practical implications and limitations of this study are provided.

We further provide a description of the methodological approach and details on the implemented prototype of a flight instructor station as part of our research simulator. In a first simulator study with four subjects the system has …

Anticipatorily Controlled Top-Down Processes Influence The Impact Of Coriolis Effects, Christine M. Talker, K. Wolfgang Kallus

International Symposium on Aviation Psychology - 2015

The impact of the vestibular-induced Coriolis illusion becomes apparent in spatial disorientation and symptoms of motion sickness. Empirical data indicated that anticipatory processes, evolved by experience, influence the sensation of Coriolis illusion. We measured subjective well-being and stress responses of 13 experienced pilots and 13 non-pilots in order to study the influence of anticipatorily controlled top-down attention on the impact of Coriolis effects and to examine the role of experience. Subjective data and psychophysiological data (EDA, ECG) were recorded, reflecting the underlying psychological processes involved. Participants distracted by doing a reaction test (experimental group) gave higher drowsiness ratings and higher …

Visual Search And Target Selection Using A Bounded Optimal Model Of State Estimation & Control, Brandon S. Perelman, Christopher W. Myers

International Symposium on Aviation Psychology - 2015

Visual attention and motor control are tightly coupled in domains requiring a human operator to interact with a visual interface. Here, we integrate a boundedly optimal visual attention model with two separate motor control models and compare the predictions made by these models against perceptual and motor data collected from human subjects engaged in a parafoveal detection task. The results indicate that humans use an optimal motor control policy limited by precision constraints – humans executed ballistic movements using near-optimal velocity (i.e., bang-bang control), but imprecision in those movements often caused participants to overshoot their targets, necessitating corrective action. Motor …

An Ecological Approach To The Supervisory Control Of Uav Swarms, Christian Fuchs, Clark Borst, Guido De Croon, Rene Van Paassen, Max Mulder

International Symposium on Aviation Psychology - 2015

Advances in miniaturized computer technology have made it possible for a single Unmanned Aerial Vehicle (UAV) to complete its mission autonomously. This also sparked interest in having swarms of UAVs that are cooperating as a team on a single mission. The level of automation involved in the control of UAVswarms will also change the role of the human operator. That is, instead of manually controlling the movements of the individual UAVs, the system operator will need to perform higher-level mission management tasks. However, most ground control stations are still tailored to the control of single UAVs by portraying raw flight …

Developing Quantitative Air Traffic Risk-Benefit Pathways For Class Delta Airports: Improving Small Tower Operations, Katherine A. Berry, Michael W. Sawyer, Jordan Hinson

International Symposium on Aviation Psychology - 2015

The primary responsibility of an Airport Traffic Control Tower (ATCT) controller is to prevent collisions between aircraft and other hazards on the surface and in the immediate vicinity. The safety service provided by controllers at towers with larger operations greatly exceeds the costs of establishing those towers. As the number of operations decreases, the costs of operating the tower may begin to outweigh the benefits of staffing the tower. Safety event reports describing instances where an ATCT controller provided a service that reduced the consequences of the event were collected. The reports were classified to identify latent factors, causal factors, …

Tactile Cueing Strategies To Convey Aircraft Motion Or Warn Of Collision, Ben D. Lawson, Roger C. Cholewiak, J. Christopher Brill, Angus H. Rupert, Linda-Brooke I. Thompson

International Symposium on Aviation Psychology - 2015

This report highlights five current vibrotactile display technologies for conveying aircraft motion or approach to obstacles or waypoints, including: 1) a simple on/off vibration cue that activates when a designated position is reached; 2) vibrations whose on-off pulse rate increases as the vehicle moves faster; 3) vibrations whose fundamental frequency rises to cue the approach of an object; 4) vibrations whose body site of spatial cueing signals self-motion in a manner analogous to tactile cues during sliding along the ground; 5) vibrations whose body site of cueing expands in a manner analogous to visual looming cues. The advantages and limitations …

Audiotactile Aids For Improving Pilot Situation Awareness, J. Christopher Brill, Ben D. Lawson, Angus H. Rupert

International Symposium on Aviation Psychology - 2015

Up to one-third of all aircraft mishaps are attributable to spatial disorientation (SD), costing lives and millions of dollars. One potential solution is to provide supplementary sensory cues to help improve pilots’ situation awareness (SA). Given existing demands on the pilot’s visual system, audition and touch present the greatest potential for success. However, accurate 3D audio perception may be problematic in noisy operational environments. To determine the effects, participants performed an azimuth cue localization task while listening to 90 dB helicopter noise. Cue modalities conditions included 3D audio, vibrotactile, and audiotactile. Accuracy was better and response times were significantly faster …

Walden Faculty and Staff Publications

With the advancement of modern technology, the internet has become a standard platform for many forms of communication and education. The majority of pregnant females fall into the cohort known as Millenials and have experienced technology since early in life. Millenials consider technology as part of their everyday life and use it for personal interaction or a source of information. The established comfort with the use of technology combined with busy lifestyles, multiple commitments, transportation costs or logistics, childcare, or a desire for privacy, support the use of perinatal online learning. This article examines options that childbirth educators may consider …

Cyp2a6 Polymorphisms May Strengthen Individualized Treatment For Nicotine Dependence, Yawo M. Akrodou

Walden Faculty and Staff Publications

Each CYP2A6 gene variant metabolizes nicotine differently depending on its enzymatic activities. The normal nicotine metabolizer CYP2A6*1A is associated with high scores of nicotine dependence (5-10) on the Fagerström Test for Nicotine Dependence (FTND) scale because it encodes for enzymes that catalyze nicotine 100%. Slow nicotine metabolizers (i.e., CYP2A6*1H, CYP2A6*4A, CYP2A6*9, and CYP2A6*12A) are associated with underrated nicotine metabolizing activity (50%-75%), linking them to low scores for nicotine dependence (0-4) on the FTND scale. In a clinical trial involving the use of bupropion, people who were carriers of slow nicotine metabolizers were found to have a tendency to maintain abstinence …

Specific N-Glycans Of Hepatocellular Carcinoma Cell Surface And The Abnormal Increase Of Core-Α-1, 6-Fucosylated Triantennary Glycan Via N-Acetylglucosaminyltransferases-Iva Regulation, Huan Nie, Xia Liu, Yubao Zhang, Tingting Li, Chao Zhan, Wenjuan Huo, Anshun He, Yuanfei Yao, Yu Jin, Youpeng Qu, Xue-Long Sun, Yu Li

Chemistry Faculty Publications

Glycosylation alterations of cell surface proteins are often observed during the progression of malignancies. The specific cell surface N-glycans were profiled in hepatocellular carcinoma (HCC) with clinical tissues (88 tumor and adjacent normal tissues) and the corresponding serum samples of HCC patients. The level of core-α-1,6-fucosylated triantennary glycan (NA3Fb) increased both on the cell surface and in the serum samples of HCC patients (p < 0.01). Additionally, the change of NA3Fb was not influenced by Hepatitis B virus (HBV)and cirrhosis. Furthermore, the mRNA and protein expression of N-acetylglucosaminyltransferase IVa (GnT-IVa), which was related to the synthesis of the NA3Fb, was substantially increased in HCC tissues. Knockdown of GnT-IVa leads to a decreased level of NA3Fb and decreased ability of invasion and migration in HCC cells. NA3Fb can be regarded as a specific cell surface N-glycan of HCC. The high expression of GnT-IVa is the cause of the abnormal increase of NA3Fb on the HCC cell surface, which regulates cell migration. This study demonstrated the specific N-glycans of the cell surface and the mechanisms of altered glycoform related with HCC. These findings lead to better understanding of the function of glycan and glycosyltransferase in the tumorigenesis, progression and metastasis of HCC.
