The Psychology Of Aviation Surprise: An 8 Year Update Regarding The Noticing Of Black Swans, Christopher D. Wickens Jan 2009

The Psychology Of Aviation Surprise: An 8 Year Update Regarding The Noticing Of Black Swans, Christopher D. Wickens

International Symposium on Aviation Psychology - 2009

We describe the limitation that people have in noticing very unexpected, surprising “offnominal”, or black swan events, as reflected in the psychology of change blindness; and how this limitation can compromise aviation safety. We then describe a three phase program of research examining pilot response to these black swan events, using (1) a meta-analysis to reveal the miss rate in noticing black swans, (2) a model of visual attention to predict this miss rate, and (3) the same model to make predictions regarding the safety impact of NextGen technology and procedures.

International Symposium on Aviation Psychology - 2009

I want to briefly share some of our early work at the University of Illinois Aviation Research Laboratory relating to the nature and role of motion cueing and its relationship to pilot performance in flight training, skill evaluation, and flight instrument utilization. First, though, I’d like to offer some personal testimony about Stan Roscoe, the director of the Lab, so that you can appreciate the extraordinary environment we were provided in which to pursue our research and to learn.


The Role Of Common Methods In Personnel Selection, Thomas R. Carretta Jan 2009

The Role Of Common Methods In Personnel Selection, Thomas R. Carretta

International Symposium on Aviation Psychology - 2009

Cognitive ability is the most widely researched psychological construct in studies of determinants of occupational performance. Results of meta-analyses of common selection methods in personnel psychology indicate that general mental ability (g) is the best predictor of training and job performance involving core technical proficiency. For training, the predictiveness of g is incremented by measures of personality and specialized job knowledge. For job incumbents, the predictiveness of g is incremented by personality, job knowledge, and work sample performance. In addition to the predictive validity of g, personality, and prior job knowledge, their role in the acquisition of additional job knowledge …


Simulation Results For Highlighting Runway Safety Critical Information On Cockpit Displays Of Traffic Information, Peter Moertl Jan 2009

Simulation Results For Highlighting Runway Safety Critical Information On Cockpit Displays Of Traffic Information, Peter Moertl

International Symposium on Aviation Psychology - 2009

This paper describes the results of a human in the loop simulation that evaluated enhancements to a Cockpit Display of Traffic Information (CDTI). Runway safety critical information was highlighted on the CDTI to facilitate flight crew situation awareness and conflict detection for different groups of pilots (General Aviation and commercial) and under different operational settings (crew and single pilot). The evaluated CDTI enhancements are currently being defined by RTCA Special Committee 186 and based on the use of Automatic Dependent Surveillance-Broadcast (ADS-B). The results suggest that highlighting of certain traffic relevant information is promising to increase pilot’s hazard detection over …


Towards A Meaningful Presentation Of Fms Trajectory Information For Tactical Self-Separation, S.B.J. Van Dam, M. Mulder, M.M. (René) Van Paassen Jan 2009

Towards A Meaningful Presentation Of Fms Trajectory Information For Tactical Self-Separation, S.B.J. Van Dam, M. Mulder, M.M. (René) Van Paassen

International Symposium on Aviation Psychology - 2009

In the context of future airspace management concepts, the flight crew will need tactical navigation support for airborne self-separation. Applying ecological interface design principles, a state-based navigation tool was designed that uses functional information overlays that show how traffic and aircraft performance constrain the horizontal maneuvering. The state-based system has been enhanced with a visualization of intent information from the flight plan trajectory (Van Dam, Paassen, & Mulder, 2007). This paper discusses in detail the exchange of intent information using ADS-B. It presents some promising ideas to show intent in a more meaningful and pilot-intuitive way, particularly focusing on the …


A Methodology And Tools For The Prospective Identification Of Nextgen Human Factors Issues, Ken Funk Jan 2009

A Methodology And Tools For The Prospective Identification Of Nextgen Human Factors Issues, Ken Funk

International Symposium on Aviation Psychology - 2009

The Human-Machine Systems Engineering Methodology (HMSEM) is a systematic method to prospectively identify relevant human fallibilities, potential errors, and general human factors issues in a complex, high-risk system, then develop design recommendations for remediations to counteract the fallibilities, avoid or mitigate the errors, and resolve the issues. HMSEM uses IDEF0 functional modeling, task analysis, human fallibilities analysis, and Failure Modes and Effects Analysis, organizing the information for and from the analyses in a workbook. The results of its application to several tasks on the NextGen flight deck suggest that it can be a valuable complement to other means to anticipate …

An Interface For Inbound Traffic Route Planning, Ewout S. Van Dijk, M.M. (René) Van Paassen, Max Mulder, Mariska I. Roerdink Jan 2009

An Interface For Inbound Traffic Route Planning, Ewout S. Van Dijk, M.M. (René) Van Paassen, Max Mulder, Mariska I. Roerdink

International Symposium on Aviation Psychology - 2009

It is expected that, with increasing automation, the emphasis in the air traffic controllers’ work will shift from tactical control towards supervision and planning of aircraft trajectories. To support this work, a planning interface for area controllers has been developed. The interface uses a normal Plan View Display (PVD) supplemented with a Time-Space Diagram (TSD), that visualizes the travel of the incoming aircraft across their planned track. With the constraints on speed and timing as given in the TSD, the interface permits direct manipulation of the arrival time within these constraints. Using a simulation of air traffic, the interface was …


Analysis Of Ramp Damage Incidents And Implications For Future Composite Aircraft Structure, Barbara G. Kanki Ph.D., Connie L. Brasil Jan 2009

Analysis Of Ramp Damage Incidents And Implications For Future Composite Aircraft Structure, Barbara G. Kanki Ph.D., Connie L. Brasil

International Symposium on Aviation Psychology - 2009

As aircraft manufacturers use increasing amounts of composite materials in primary aircraft structures, an understanding of how composite damage may occur is crucial. One likely setting for composite damage events is the ramp and gate areas where “ramp rash” is a common occurrence. Costly consequences to airlines and the potential to jeopardize safety are an everyday hazard. In order to better understand how such events unfold in today’s operations, 104 ramp damage reports that were voluntarily submitted to the NASA Aviation Safety Reporting System (ASRS) were analyzed. Factors including environmental conditions, aircraft state, aircraft damage locations and types of ramp …

It describes the methodology that was used, presents representative issues from the list that resulted, and makes recommendations to continue work to update the list and use it as the basis for suggested NextGen flight deck standards and design requirements.


Assisting Air Traffic Control In Planning And Monitoring Continuous Descent Approach Procedures, A. Van Der Eijk, M. Mulder, M.M. (René) Van Paassen, A. C. In ‘T Veld Jan 2009

Assisting Air Traffic Control In Planning And Monitoring Continuous Descent Approach Procedures, A. Van Der Eijk, M. Mulder, M.M. (René) Van Paassen, A. C. In ‘T Veld

International Symposium on Aviation Psychology - 2009

In advanced noise abatement procedures, the approach of an aircraft is optimized to reduce the noise on the ground. A drawback of many noise abatement procedures is that air traffic controllers are forced to increase spacing, leading to a significant reduction of runway capacity. A display, named the Time-Space Diagram, has been developed to assist controllers in metering, sequencing and merging aircraft flying noise abatement procedures such as the Continuous Descent Approach. Although initial tests were promising, it was recommended that the information could be enhanced by supporting common controller spacing techniques. The improved display was tested in an experiment, …


Predicting The Unpredictable: Estimating Human Performance Parameters For Off-Nominal Events, Becky L. Hooey, Christopher D. Wickens, Ellen Salud, Angelia Sebok, Shaun Hutchins, Brian F. Gore Jan 2009

Predicting The Unpredictable: Estimating Human Performance Parameters For Off-Nominal Events, Becky L. Hooey, Christopher D. Wickens, Ellen Salud, Angelia Sebok, Shaun Hutchins, Brian F. Gore

International Symposium on Aviation Psychology - 2009

A parameter meta-analysis was conducted to characterize human responses to off-nominal events. The probability of detecting an off-nominal event was influenced by characteristics of the offnominal event scenario (phase of flight, expectancy, and event location) and the presence of advanced cockpit technologies (head-up displays, highway-in-the-sky displays, datalink, and graphical route displays). The results revealed that the presence of these advanced technologies hindered event detection reflecting cognitive tunneling and pilot complacency effects.


Risk Assessment In Aviation, Robert Mauro, Immanuel Barshi Jan 2009

Risk Assessment In Aviation, Robert Mauro, Immanuel Barshi

International Symposium on Aviation Psychology - 2009

In aviation, many actions are taken to reduce risk. However, not all risks can be avoided. To effectively manage risk, managers and regulators must evaluate and compare risks associated with different threats. Yet, it is frequently difficult to obtain reasonable assessments of these risks. Traditional approaches often produce unsatisfactory results when the probability of failure is low but the costs of failure are high -- as is often the case in modern civil aviation. Attempts to use a single dimension to evaluate threats often lead to unreliable and contentious assessments. Many risk assessment heuristics and displays can yield misleading and …


Fractal Time Series Analysis Of Human Heartbeat Intervals In A Change Blindness Task, Sheldon M. Russell, Gregory J. Funke, Camilla C. Knott, Benjamin A. Knott Jan 2009

Fractal Time Series Analysis Of Human Heartbeat Intervals In A Change Blindness Task, Sheldon M. Russell, Gregory J. Funke, Camilla C. Knott, Benjamin A. Knott

International Symposium on Aviation Psychology - 2009

Fractal analysis is a set of techniques used in the study of complex systems to understand patterns of variability that are often observed in non-linear and natural systems. These techniques have been successfully applied to the study of human physiology, such as gait, heart rate variability, and respiration (West, 2004). Understanding variability in physiological measures may provide insight into human performance, individual workload, and stress. As an exploration of the possible contributions of fractal analysis to human performance, heart rate data from an existing research study was re-analyzed using methods common in fractal analysis of time series data. Results indicate …


Situational Awareness Assessment In Flight Simulator Experiment, Henk Van Dijk, Koen Van De Merwe, Rolf Zon Jan 2009

Situational Awareness Assessment In Flight Simulator Experiment, Henk Van Dijk, Koen Van De Merwe, Rolf Zon

International Symposium on Aviation Psychology - 2009

Within the HILAS (Human Integration into the Lifecycle of Aviation Systems) project a flight simulator experiment was performed. The aim of the experiment was to study and select relevant Human Factors tools for pilot Situational Awareness assessment. One specific scenario was designed in which a malfunction of the aircraft was simulated: an Indicated Air Speed discrepancy. The malfunction was introduced during flight and slowly progressed over time while researchers monitored if and how pilots detected the discrepancy. Pilot behaviour was studied during the scenario; i.e. pilots’ Situational Awareness was assessed via eye trackers and rating scales.

Refer to our statement of position document for additional details at www.ALPA.org under Safety, HFT (Human Factors and Training). Safe and effective aviation automation∗ is only possible when human factors principles are utilized properly. We strongly encourage engineers, regulators, and operators to apply human factors considerations at every stage of aviation automation hardware, software, and procedure design. Occasionally procedures or products are implemented without these considerations. This inattention can make usage problematic and has produced unintended consequences …


Providing Evidence Of A Multiple-Process Model Of Trust In Automation, Stephen Rice, Gayle Hunt Jan 2009

Providing Evidence Of A Multiple-Process Model Of Trust In Automation, Stephen Rice, Gayle Hunt

International Symposium on Aviation Psychology - 2009

This study focuses on the effects of human responses to computer automation aids. Previous research has shown that different types of automation errors (false alarms and misses) affect human trust in different ways. False alarms tend to negatively affect operator compliance, whereas misses tend to negatively affect operator reliance. Participants were asked to determine whether an enemy target was present or absent in a series of images, a task similar to what a UAV operator might be asked to perform. A diagnostic aid provided recommendations before participants viewed each image. Reliability and type of automation error were manipulated in order …

International Symposium on Aviation Psychology - 2009

Crew Resource Management (CRM) is currently considered as one of the most effective methods for avoiding human errors or minimizing their effects. In training, measurement of the level of flight crews’ CRM Skills is necessary in order to evaluate objectively which Skills have been adequately learned and which are lacking. The Japan Aerospace Exploration Agency (JAXA) has developed CRM Skills Behavioral Markers and CRM Skills Measurement Methods that can identify a crew’s level of CRM Skills by which human errors and threats are managed. A series of simulated-LOFT (line oriented flight simulation training) were conducted to examine the applicability of …


Training Interventions To Reduce Air Force Predator Mishaps, Robert Nullmeyer, Gregg Montijo Jan 2009

Training Interventions To Reduce Air Force Predator Mishaps, Robert Nullmeyer, Gregg Montijo

International Symposium on Aviation Psychology - 2009

The use of unmanned aerial systems (UASs) is expanding rapidly. In military operations, this increased use has been accompanied by relatively high mishap rates compared with rates across more mature manned aircraft. These higher rates led to multiple high-level reviews of unmanned operations, but surprisingly little consensus emerged across reports regarding root causes. To help close this gap, Air Force Predator Class A mishap reports through FY 2008 were analyzed in detail. Mishap rates, counts, and causal factors appeared to shift systematically over time, with an increase in mishap reports citing shortfalls in several skill and knowledge areas in FY …

Proposing Attitude Indicator Modifications To Aid In Unusual Attitude Recovery, Nathan B. Maertens Jan 2009

Proposing Attitude Indicator Modifications To Aid In Unusual Attitude Recovery, Nathan B. Maertens

International Symposium on Aviation Psychology - 2009

Pilots’ inability to recover from unusual attitudes (UA) is a major factor in loss of control in-flight (LOCIF) accidents, the largest cause of commercial aviation fatalities (Boeing, 2008). One study found 58% of professional pilots and 72% of general aviation pilots were unable to recover from LOCIF upsets (Regional Aviation News, 2008). Statistics also show that LOCIF is the only fatal aviation accident type not to appreciably decrease over a 21 year period ending in 2002 (Sumwalt, 2003a). A revision of the attitude indicator (AI) is proposed to examine if this would reduce the problem by keeping pilots from flying …


A Compatibility Analysis Of Attitude Display Formats, Motonori Yamaguchi, Robert W. Proctor Jan 2009

A Compatibility Analysis Of Attitude Display Formats, Motonori Yamaguchi, Robert W. Proctor

International Symposium on Aviation Psychology - 2009

The present research investigated factors that contribute to the compatibility of attitude display formats with actions taken to control an aircraft. In three experiments, participants performed a speeded response task in which they responded by banking an aircraft according to a nonspatial aspect of lateralized stimuli. The format of attitude display was horizon-moving or aircraftmoving, and each participant used normal and reversed controls. These manipulations dissociated influences of three response factors (aircraft, display, hand) on the stimulus-response compatibility, or Simon, effect. The influences of the three factors on the Simon effect were nearly additive, and their contributions depended on the …

The objectives of this study were to: validate a multidimensional measure of display clutter for advanced head-up displays (HUDs) incorporating enhanced and synthetic vision systems (EVS/SVS); assess the influence of HUD configuration on pilot perceptions of display clutter and flight performance; and model clutter scores in terms of visual display properties. Eighteen pilots flew a flight simulator in a landing approach using three different sets of HUD configurations (low, medium, or high clutter). Pilot ratings of overall display clutter and its underlying dimensions were recorded along with flight performance measures (deviations from localizer, glideslope, altitude and approach speed). A display …


Design Of An Ecological Vertical Separation Assistance Cockpit Display, F. M. Heylen, S.B.J. Van Dam, M. Mulder, M.M. Van Paassen Jan 2009

Design Of An Ecological Vertical Separation Assistance Cockpit Display, F. M. Heylen, S.B.J. Van Dam, M. Mulder, M.M. Van Paassen

International Symposium on Aviation Psychology - 2009

A tactical navigation support tool was designed to effectively deal with conflict situations in the vertical plane, while preserving travel freedom as much as possible. Based on Ecological Interface Design principles, the Vertical Separation Assistance Display is developed as an extension to the existing Vertical Situation Display. Functional information is presented via overlays that show pilots how their vertical maneuvering possibilities are constrained by ownship performance, and by limits imposed by surrounding traffic. A questionnaire-based evaluation shows that the ecological overlays considerably improved pilot traffic awareness in vertical conflict situations.

Contribution Of High-Frequency Eeg Features To Physiogicallybased Operator Workload Estimation, Jason W. Monnin, Justin R. Estepp Jan 2009

Contribution Of High-Frequency Eeg Features To Physiogicallybased Operator Workload Estimation, Jason W. Monnin, Justin R. Estepp

International Symposium on Aviation Psychology - 2009

Physiologically-based cognitive workload assessment can discriminate changing levels of operator functional state in complex task environments. In this paradigm, electroencephalography (EEG) is a commonly used physiological measure. Spectral power in clinical frequency bands is used to derive features to train an artificial neural network (ANN) classifier to recognize changes in cognitive workload. Recent research has suggested that power in high frequency bands may be influenced by electromyographic artifact. In a previous study, nineteen channels of EEG were recorded (from 10 participants) during a complex uninhabited air vehicle (UAV) control simulation in which task difficulty was manipulated to induce changes in …
