Adaptive Controller Adaptation Time And Available Control Authority Effects On Piloting, Anna Trujillo, Dr. Irene Gregory

International Symposium on Aviation Psychology - 2013

Adaptive control is considered for highly uncertain, and potentially unpredictable, flight dynamics characteristic of adverse conditions. This experiment looked at how adaptive controller adaptation time to recover nominal aircraft dynamics affects pilots and how pilots want information about available control authority transmitted. Results indicate that an adaptive controller that takes three seconds to adapt helped pilots when looking at lateral and longitudinal errors. The controllability ratings improved with the adaptive controller, again the most for the three seconds adaptation time while workload decreased with the adaptive controller. The effects of the displays showing the percentage amount of available safe flight …

Man-Machine Symbiosis In Aviation: New Risks And Capabilities In View Of Information Technology Expansion, Oleksandr Petrenko

International Symposium on Aviation Psychology - 2013

The paper examines possibility of the impact of modern technology on the manmachine symbiosis in aviation. Presented some data concerning the perception of a pilots in a highly automated cockpit. The first results of empirical research make it possible to assume that aircraft systems can be customized to adjust to individual typological characteristics of operators. The paper discusses the language modality perspectives of a man-machine interaction. Creating modern sociotechnical systems aimed at a human at a completely new level has special requirements to an integration of designer and operational psychological outlooks.

Assessing The Efficacy Of Situation Awareness Probe Questions For Predicting Airtraffic- Management Performance, James D. Miles, Kim-Phuong L. Vu, Dan Chiappe, Thomas Strybel, Vernol Battiste

International Symposium on Aviation Psychology - 2013

We conducted an exploratory data analysis as a step toward modeling components of SA. It was based on data collected from situation awareness probe questions that were used in large-scale air traffic control simulations over 5 semesters of an ATC radar internship in the Center for Human Factors in Advanced Aeronautics Technologies (CHAAT). Three components of SA were generated by a principal component analysis that we label “Action Relevant,” “Distance R and “Low Priority.” The analyses provide a data-driven scheme for categorizing probes relate SA that can be used in future evaluations of NextGen concepts and technologies.

A Situation Awareness Design Approach To The Position Of Airline Maintenance Control In A Simulated Operations Control Center, Durant Camron Bridges Iii

Student teams participate in a simulated work shift to further improve problem solving skills and coordination among senior-level undergraduate students.

The Effectiveness Of Microsoft Flight Simulator As A Training Aid For Private Pilot Training And Proficiency, Wendy S. Beckman

International Symposium on Aviation Psychology - 2013

The debate regarding the effectiveness of computer-based software for pilot training and proficiency has been ongoing since such software first became available. While studies on the efficacy of such software have been and continue to be conducted, pilots are in large number utilizing such packages. A nationwide survey was conducted to determine how the Microsoft Flight Simulator (MFS) software package is being used by pilots for both initial private pilot training and for maintaining proficiency once certificated. Over 650 survey respondents evaluated the effectiveness of MFS in 14 areas of pilot operations. It was found that over 40% of respondents …

Detecting Fatigue In Commercial Flight Operations Using Physiological Measures, Lisa C. Thomas, Kimberly Craig, Christopher Gast, Robert Grube, Mike Muhm, Emma Romig

International Symposium on Aviation Psychology - 2013

The purpose of this study is to determine whether any technology exists to unobtrusively, reliably, and accurately detect symptoms of fatigue in real time before fatigue affects performance. Airline pilots are fitted with a variety of physiological measurement devices (e.g. EEG, blink rate, etc.) that have been demonstrated in the literature to be related to fatigue. Each crew of two pilots performs simulated gate-to-gate flight operations under rested and fatigued conditions, during which physiologic and performance parameters are continuously monitored. In addition, audio, video, and simulator data are recorded for post-session evaluation. Ultimately, if one or more technologies proves effective, …

Enhancing Helicopter-Pilot Obstacle Avoidance Using A Binocular Head-Mounted Display, Dennis B. Beringer, Gena Drechsler

International Symposium on Aviation Psychology - 2013

Twenty-three helicopter pilots flew a simulated Bell 206 in Helicopter Emergency Medical Service (HEMS) scenarios with obstructions present. In Study 1, the head-mounted display (HMD) showed highway-in-the-sky guidance but not obstructions. Study 2 added obstructions (broadcast towers, power lines) in the HMD. Pilots detected and avoided HMD-depicted obstructions earlier than those only shown out the window. Wire strikes were frequent without HMD depictions of obstructions but were greatly reduced when these objects were shown in the HMD. They were completely eliminated when a red warning fence was overlaid on the power-line graphic at the point it transected the flight path. …

Supervisory Control State Diagrams To Depict Autonomous Activity, Michael Patzek, Clayton Rothwell, George Bearden, Benjamin Ausdenmoore, Allen Rowe

International Symposium on Aviation Psychology - 2013

As capabilities of autonomous systems expand, traditional geospatial information displays used for supervisory control will likely need to be augmented with more explicit information on higherorder autonomous activities, such as goal-directed task selection, situation assessment, decisionmaking, and planning. We present a supervisory control interface for higher-order autonomy based on finite state machine diagrams called Layered Pattern Recognizable Interfaces for State Machines (L-PRISM). L-PRISM is a hierarchically arranged set of nested state diagrams coupled with a temporal control and payload viewer. The mission goals and tasks are at the top-most layer and sub-tasks and states at lower layers, providing varying levels …

The Effects Of Stereoscopic Radar Displays On Air Traffic Controller Performance, Jason G. Russi, Brent T. Langhals, Michael E. Miller, Eric Heft

International Symposium on Aviation Psychology - 2013

Controllers identify vertical separation in aircraft depicted on 2-D radar displays by calculating altitude from numerical values. This is used to create a 3-D mental image to determine vertical spacing; a mentally fatiguing practice. Current stereoscopic display technology exists that may allow reduction of this aspect of controller workload. With a near doubling of traffic expected within the next two decades (FAA, 2012), controllers’ abilities to rapidly interpret spacing and maintain awareness will become increasingly imperative to safety. A stereoscopic radar simulator was developed and field-tested with 35 USAF controllers. It presented a top-down view, similar to traditional radar displays, …

Does Supplementary Computer Generated Cueing Enhance Controller Efficiency In A Congested Communication Environment?, Laurienne C.R.A. Santana, Brent T. Langhals, Michael E. Miller, Vic Finomore

International Symposium on Aviation Psychology - 2013

Air traffic controllers are often required to simultaneously communicate with several aircraft over multiple radio frequencies. As a result, during peak loading, it is common for the controller to receive multiple concurrent communications, each from a different aircraft, making it difficult to discern all necessary auditory communications. To address this problem, a modified air traffic control (ATC) interface was prototyped with the goal of increasing controller-to-pilot communication efficiency. This prototype involved an automated text to speech system which displayed supplementary text in an on-screen text box, echoing aircraft transmissions in the event of an indiscernible radio call. The prototype was …

Exploring The Effects Of Working Memory Capacity, Attention, And Expertise On Situation Awareness In A Flight Simulation Environment, Orçun Orkan Özcan, Murat Perit Çakır, Bilge Say

International Symposium on Aviation Psychology - 2013

Simulator pilots are subject to some of the constraints of a real flight situation in a PC based flight simulation. Situation awareness (SA) for simulator pilots was explored in terms of underlying cognitive aspects by analyzing the compound effects of expertise, working memory, inhibition and divided attention. Online and Offline SA measurements were analyzed with expertise and scores of Automated Operation Span Task, Stroop and Coşkunöz visual attention tasks. Regression analyses revealed the expected relationships of simulator pilots’ SA with expertise and inhibition capacity but not with working memory and divided attention capacity. Obtained results were also compared to those …

Review Of Pilot Performance And Pilot-Automation Interaction Models In Support Of Nextgen, Angelia Sebok, Christopher D. Wickens

International Symposium on Aviation Psychology - 2013

Computational models of aircraft pilot performance will gain importance over the next decades, as major evolutions in the national airspace continue to emerge with the NextGen program. Evaluating new technology, or procedures such as self-separation, requires time and resourceconsuming pilot-in-the-loop (PITL) simulations. Models can augment PITL findings and they can help to constrain the scope of PITL simulations. If they are validated, such computational models may actually answer some design questions in place of PITL simulations. This paper summarizes a review of modeling efforts to address pilot performance, and elaborates on pilot-automation interaction models.

Applying Systems Thinking To Aviation Psychology, Nancy G. Leveson

International Symposium on Aviation Psychology - 2013

Hazard analysis is at the heart of system safety. It can be described succinctly as “investigating an accident before it happens.” A hazard is selected, such as two aircraft violating minimum separation standards or an aircraft losing sufficient lift to maintain altitude, and then the scenarios that can lead to that hazardous state are identified. Hazards are informally defined here as precursor states to accidents that the designer never wants the system to get into purposely. The resulting scenarios or potential paths to the hazard are then used to compute the probability of the hazardous state occurring or to design …

Air Transport Incident And Accidents Caused By Crew Situation Awareness Errors, Robert L. Arnold

International Symposium on Aviation Psychology - 2013

This paper examines the various aircrew situation evaluation errors that resulted in one near fatal commercial airline incident and two fatal commercial airline accidents. The incident and accidents involved events that distracted the aircrews from a timely and accurate evaluation of the emergency situations that confronted them. Summary narratives of the incident and each of accidents are provided. Each emergency situation is examined to identify the distractions that caused the crews to misinterpret the nature of the emergencies they faced. Situation awareness as a construct is briefly reviewed. Recommendations for situation awareness training for aircrews are made. Recommendations are also …

Narrative Abilities Of Optimal Outcome Children And Adolescents With A Previous History Of Autism Spectrum Disorder (Asd), Joyce Suh

Master's Theses

Background: Autism Spectrum Disorders (ASDs) have traditionally been considered a lifelong condition; however there appear to be a subset of people who make such significant improvements that they no longer meet diagnostic criteria for autism. The current study examines whether these “optimal outcome” (OO) children and adolescents continue to have subtle language and socio-cognitive deficits. Method: The narratives of 15 children and adolescents with a history of ASD who achieved optimal outcomes (OO), 15 high-functioning children and adolescents with a current ASD diagnosis (HFA), and 15 typically developing peers (TD) were evaluated. Results: OO children and adolescents have few residual …

Randomized Clinical Trial Of Cognitive Behavioral Therapy (Cbt) Versus Acceptance And Commitment Therapy (Act) For Mixed Anxiety Disorders, Joanna Arch, Georg Eifert, Carolyn Davies, Jennifer C. Plumb Vilardaga, Raphael D. Rose, Michael G. Craske

Psychology Faculty Articles and Research

Objective—Randomized comparisons of acceptance-based treatments with traditional cognitive behavioral therapy (CBT) for anxiety disorders are lacking. To address this research gap, we compared acceptance and commitment therapy (ACT) to CBT for heterogeneous anxiety disorders.

Method—One hundred twenty eight individuals (52% female, mean age = 38, 33% minority) with one or more DSM-IV anxiety disorders began treatment following randomization to 12 sessions of CBT or ACT; both treatments included behavioral exposure. Assessments at pre-treatment, post-treatment, 6-month, and 12-month follow-up measured anxiety specific (principal disorder Clinical Severity Ratings [CSR], Anxiety Sensitivity Index, Penn State Worry Questionnaire, Fear Questionnaire avoidance) and …
