Maneuver Stereotypes In Airborne Conflict Resolutions, Esa M. Rantanen, Christopher D. Wickens, David Keller

International Symposium on Aviation Psychology - 2009

The roles and responsibilities of air traffic controllers and pilots are shifting in the advent of the NextGen air traffic management infrastructure, which also involves high levels of automation. It is important to understand just how large departures from the current ingrained practices the NextGen procedures represent, particularly in extremely safetycritical tasks such as airborne conflict resolutions. Pilots’ conflict resolution maneuver preferences have received some attention, but corresponding research on air traffic controllers’ practices is almost nonexistent. We analyzed 87 samples of aircraft track data involving conflict alerts and subsequent resolution maneuvers from Atlanta center. Vertical conflict resolution maneuvers were …

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 …

International Symposium on Aviation Psychology - 2009

We describe recent developments in an ongoing program to design work-centered C2 support for a military airlift organization. Work-centered design tailors support to the cognitive and collaborative demands of the work. A coordinated suite of visualizations was developed to support synchronized replanning in response to dynamically changing conditions by revealing the interrelationships and constraints across multiple missions distributed in time and space. Support included the ability to perform ‘what if’ simulations across multiple missions so as to assess the impact of a change in one mission on other missions. An empirical evaluation was conducted comparing target user replanning performance on …

Attitudes Toward Automation And Information Requirements Of Experienced Predator Operators, William P. Marshak, John Hudson, Jeff Collier Jan 2009

Attitudes Toward Automation And Information Requirements Of Experienced Predator Operators, William P. Marshak, John Hudson, Jeff Collier

International Symposium on Aviation Psychology - 2009

Two simulation studies were conducted using the Multiple Uninhabited Air Vehicle Agency (MAGE) software with nine Predator experienced pilots and sensor operators. In one study, MAGE's situation awareness and decision support elements were employed as supplemental information displays to a Predator crew station simulation within the Air Force's SIMAF facility. In the second simulation, each pilot controlled two autonomous UAVs during a complex multi-target mission scenario using the MAGE software suite. After the simulations were complete, the crewpersons answered questions about their attitudes concerning automated features and what kinds of non-vehicle information (weather, air spaces, intelligence, etc.) they felt they …

Psychological Fidelity Of Simulator Human Performance Limitation Training, K. Wolfgang Kallus Jan 2009

Psychological Fidelity Of Simulator Human Performance Limitation Training, K. Wolfgang Kallus

International Symposium on Aviation Psychology - 2009

Fidelity of simulators for training of pilots has to be judged from the final end of the training goal. This conclusion can be derived from the overview of Hays & Singer (1989), which has been published a considerable time ago. Nevertheless, an ongoing debate questions the need of simulator features like motion for the training of pilots – partly without giving attention to the training goals at hand. Especially in the area of threat and error management requirements for the simulators differ markedly from operational recurrence training. For experienced ATPL- pilots we can assume that a high fidelity visual simulation …

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 …

The Effect Of Video Weather Training Products On General Aviation Pilots’ Flight Behavior, William Knecht, Jerry Ball Jan 2009

The Effect Of Video Weather Training Products On General Aviation Pilots’ Flight Behavior, William Knecht, Jerry Ball

International Symposium on Aviation Psychology - 2009

This study examined the effect of video weather training products on general aviation (GA) pilot flight behavior. Fifty pilots participated. Training products were two popular GA weather training videos, plus a non-weather video as control. Pilots watched one video. Then, in the CAMI flight simulator, they flew a challenging 1.5-h visual flight rules (VFR) mission. Along the route, terrain rose slowly, with cloud bases squeezing pilots between ground and clouds. The control group penetrated significantly farther into the deteriorating weather. Otherwise, no significant safety differences were observed for time spent in instrument meteorological conditions (IMC), time scud running, or time …

Solution Space-Based Complexity Analysis Of Atc Aircraft Merging Tasks, Patrick Hermes, Max Mulder, M.M. (René) Van Paassen, Hans Huisman, J.H.L. (Harjan) Boering Jan 2009

Solution Space-Based Complexity Analysis Of Atc Aircraft Merging Tasks, Patrick Hermes, Max Mulder, M.M. (René) Van Paassen, Hans Huisman, J.H.L. (Harjan) Boering

International Symposium on Aviation Psychology - 2009

Air traffic controller workload is considered to be a limiting factor in the growth of air traffic. In this paper a new method of assessing controller task demand load will be developed and tested. Based on the hypothesis that workload is primarily caused by the complexity of the task to be conducted, the concept of the “solution space” is described. For any particular air traffic control problem, the solution space describes the constraints in the environment that limit (and therefore, guide) air traffic controller decisions and actions. The complexity of that particular control problem can then be analyzed by considering …

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.

Implementation Issues For Uav Camera View Transition Display Aid, Nicholas Wright, Heath Ruff, Brian Mullins, Antonio Ayala, Gloria Calhoun, Mark Draper Jan 2009

Implementation Issues For Uav Camera View Transition Display Aid, Nicholas Wright, Heath Ruff, Brian Mullins, Antonio Ayala, Gloria Calhoun, Mark Draper

International Symposium on Aviation Psychology - 2009

An operator supervising multiple unmanned aerial vehicles (UAVs) will be required to switch attention between UAVs, each potentially involving different scenario environments and task requirements. A transition aid is now under evaluation that employs synthetic vision technology to enhance an operator’s situation awareness when switching between UAVs. Instead of discretely switching from the camera view of one UAV to the camera view of another, the algorithms driving the transition automatically provide a display format that uses a “fly out, fly in” metaphor over several seconds to transition between the two camera views. This paper will describe the many parameters that …

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 …

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 …

Automation Dependency Under Time Pressure, Stephen Rice, David Keller, Gayle Hunt, David Trafimow Jan 2009

Automation Dependency Under Time Pressure, Stephen Rice, David Keller, Gayle Hunt, David Trafimow

International Symposium on Aviation Psychology - 2009

Previous research has identified many factors that affect human dependence on automated systems. Some of these factors include automation reliability, types of errors, and training. This study introduces a new factor, time pressure, which is directly related to operator dependence on automated aids. Participants were asked to perform a simulated UAV target-detection task with the aid of diagnostic automation. Two factors were manipulated in this study: reliability of the automation and time pressure. The results indicate that participants faced with time pressure were more likely to depend on the automation than participants who had more time to evaluate the recommendations. …

Speech Synthesis For Data Link: A Study Of Overall Quality And Comprehension Effort, Martine Godfroy, Durand R. Begault, Elizabeth M. Wenzel

International Symposium on Aviation Psychology - 2009

This study investigated subjective preference for synthesized “spoken data link” messages to provide initial design guidance for communication displays in the context of NextGen (Next Generation Air Transport System) operations. Ratings of Overall Quality and Comprehension Effort were obtained as a function of voice type, synthesized speech rate, and sentence prosody. Rank-order data analyses showed that both Overall Quality and Comprehension Effort were affected by speech rate: under the “Fast Rate” condition (vs. “Default Rate”), Overall Quality decreases and Comprehension Effort increases. However, the introduction of “Prosodic Emphasis” (pitch and level changes for specific phrases) in Fast Rate sentences produced …

Ecological Synthetic Vision Display To Support Pilot Terrain Awareness, C. Borst, M. Mulder, M.M. (René) Van Paassen Jan 2009

Ecological Synthetic Vision Display To Support Pilot Terrain Awareness, C. Borst, M. Mulder, M.M. (René) Van Paassen

International Symposium on Aviation Psychology - 2009

A Synthetic Vision Display is generally believed to support pilot terrain awareness. Many studies have shown, however, that perspective views are biased, which can cause pilots to make judgment errors regarding the relative location, height, and ultimately the avoidance of terrain obstacles. Therefore, this system is usually backed by terrain avoidance systems that provide explicit resolutions to circumvent conflicts. They are, however, far from optimal regarding terrain awareness as they fail to present the rationale of the automation. This paper presents an extension to a Synthetic Vision Display that promotes pilot terrain awareness by means of overlays that reveal the …

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 …

The Use Of Intraocular Lenses With Advance Aviation Displays., Walter J. Protheroe Jr., Gerald L. Haynes

International Symposium on Aviation Psychology - 2009

With an aging aviation population, the use of intraocular lenses (IOLs) has become common place throughout the world for correcting vision acuity, cataracts and eye injuries. The material which comprises an IOL will cause a change in spectral sensitivity seen by the recipient. This is most notable in color variations while viewing Advance Aviation Displays. The results reported here are for one specific composition of IOL given to us by the manufacturer, and are assumed to be or have been in wide use. Cost limitations required that we used color correction filters to simulate colorized IOLs (not actual colorized lenses), …

Review Of Safety Reports Involving Electronic Flight Bags, Divya C. Chandra, Andrew Kendra Jan 2009

Review Of Safety Reports Involving Electronic Flight Bags, Divya C. Chandra, Andrew Kendra

International Symposium on Aviation Psychology - 2009

Electronic Flight Bags (EFBs) are a relatively new device used by pilots. Even so, 37 safetyrelated events involving EFBs were identified from the public online Aviation Safety Reporting System (ASRS) database as of June 2008. In addition, two accident reports from the National Transportation Safety Board (NTSB) cite EFB as a contributing factor. Underlying EFB issues were ascribed to each ASRS report by the authors based on subject matter expertise. Pilots reported issues such as configuration of the chart display and difficulty using the EFB when they were newly implemented. Both NTSB reports identified use of an EFB for calculation …
