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 …

Effects Of Workload On Measures Of Sustained Attention During A Flight Simulator Night Mission, Hans-Juergen Hoermann, Patrick Gontar, Andreas Haslbeck

International Symposium on Aviation Psychology - 2015

N=60 commercial airline pilots holding valid ATPLs flew a manual ILS approach following a weather induced missed approach during a night mission in full flight simulators. Measures of subjective fatigue, sustained attention, and the NASA Taskload Index were collected before and after the mission. In addition, sleep history data were available covering three days prior to the simulator. Both subjective and objective measures of fatigue showed significant ascent over the three hours of the experimental procedure. While sleep history data and roster information were related to both the overall level of fatigue and to reaction times, pilots who experienced a …

Army Aviation Manned-Unmanned Teaming (Mum-T): Past, Present, And Future, Grant Taylor, Terry Turpin

International Symposium on Aviation Psychology - 2015

As the use of unmanned aircraft systems (UAS) in military operations has increased, so too have their capabilities. One recently developed capability is the ability to operate in conjunction with traditional manned aircraft through a process called manned-unmanned teaming (MUM-T), allowing manned aviators to benefit from the unique capabilities of UAS. This paper provides an introduction to the concept of MUM-T, describing the early stages of research and development, current MUM-T capabilities in fielded Army systems, and planned future development efforts to continue to advance the capability.

Optimizing Performance Of Trainees For Uas Manpower, Interface And Selection (Optumis): A Human Systems Integration (Hsi) Approach, Jennifer Pagan, Dr. Randy Astwood, Cdr Henry Phillips

International Symposium on Aviation Psychology - 2015

Unmanned Aerial System (UAS) operations research by Williams (2004) found that platforms which employ winged aviators (e.g., Predator) have shown higher mishaps than those that select operators that are nonpilots (e.g., Shadow). One explanation may be negative training transfer from manned to unmanned platforms as operators are separated from the aircraft, thus depriving them of a range of sensory cues (McCarley & Wickens, 2007). Another explanation for higher Predator mishaps may be associated with poor Ground Control Station (GCS) design. These varying explanations for differences in mishap rates across platforms indicate the need to address a number of Human System …

Follow-Up Examination Of Simulator-Based Training Effectiveness, Maxine Lubner, Andrew R. Dattel, Deb Henneberry, Sharon Devivo

International Symposium on Aviation Psychology - 2015

A descriptive examination of the effectiveness of a simulator-based training program for pilots was conducted. Of 55 students of varying backgrounds, but mostly with limited flight experience, 13 enrolled in an intensive, simulator-based flight training program. Within two years the remainder had enrolled in conventional collegiate flight training, supplemented with some simulator training. The students in the intensive program completed their FAA Private Pilot certificates in an average of 5 weeks (not including simulator time). Moreover, the intensive program group earned their private pilot’s certificate in statistically significantly fewer hours (M=46.03) than the conventional collegiate flight training group (M=76.06). The …

The Electrooculogram And A New Blink Detection Algorithm, Samantha L. Epling, Matt Middendorf, Michael Hoepf, Christina Gruenwald, Lucas Stork, Scott Galster

International Symposium on Aviation Psychology - 2015

Accurate and efficient real-time cognitive workload assessment has many important applications, and physiological monitoring has proven quite helpful with this assessment. One such physiological signal, the electrooculogram (EOG), can provide blink rate and blink duration measures. In a recent study, we developed and validated a robust blink detection algorithm based on the vertical EOG (VEOG). This algorithm does not require baseline data and is adaptive in the sense that it works for a wide variety of individuals without any experimenter adjustments. The performance of the algorithm is quantified using truth data based on video recordings. The algorithm produced blink rate …

Functional Complexity Failures And Automation Surprises: The Mysterious Case Of Controlled Flight Into Stall (Cfis), Lance Sherry, Robert Mauro

International Symposium on Aviation Psychology - 2015

Nineteen modern airliner Loss of Control (LOC) accidents resulting in aerodynamic stalls were analyzed. These accidents involved structurally and mechanically sound aircraft decelerating through the 1.3VStall buffer to the stall airspeed - i.e. a Controlled Flight into Stall (CFIS). The analysis produced three main observations: First, the accidents were “functional complexity” failures -- the result of a complex sequence of behaviors of the automation functions. There were no consistent: failures that triggered the events (e.g. sensor failures), effects of triggering events on the automation (e.g. mode change), or commands issued by the automation (e.g. thrust setting). Second, the pilots were …

Evaluation Of An Eye Tracking-Based Assessment And Debrief Tool For Training Next Generation Multirole Tactical Aviation Skills, Meredith Carroll, Glenn Surpris, Greg Sidor, Winston Bennett Jr.

International Symposium on Aviation Psychology - 2015

As tactical aircraft become increasingly complex, pilots’ cognitive resources will become increasingly strained, especially as more critical and multifaceted information is presented on Helmet Mounted Displays (HMDs). Therefore, it is critical to ensure training results in pilots learning optimal strategies for operating in this information-rich environment, including appropriate attention allocation between different dynamic, adjustable displays and efficient scan strategies. To achieve this, a performance assessment and debrief system was developed that incorporates eye tracking technology into an HMD-enabled multirole fighter simulation to capture and process gaze data to aid in diagnosing why a pilot error occurred. The system utilizes eye …

Modeling Task Prioritization Behaivors In A Time-Pressured Multitasking Environment, Takeaki Toma, Kenneth H. Funk Ii

International Symposium on Aviation Psychology - 2015

Cockpit task management (CTM) theory is structurally consistent with cognitive multitasking models. Based on the CTM framework, it is hypothesized that aviation task prioritization behavior in human multitasking may be influenced by importance, urgency, performance status, salience, and workload of tasks in a cockpit. A middle fidelity flight simulation study was conducted to test the above hypotheses. Questionnaire data indicated that the perceived task importance, the perceived task urgency and the perceived task salience had significant relationships with the perceived task priority after taking the individual difference and flight situational difference into account. The perceived task priority was related to …

Physiological Indicators Of Workload In A Remotely Piloted Aircraft Simulation, Michael Hoepf, Matt Middendorf, Samantha Epling, Scott Galster

International Symposium on Aviation Psychology - 2015

Toward preventing performance decrements associated with mental overload in remotely piloted aircraft (RPA) operations, the current research investigated the feasibility of using physiological measures to assess cognitive workload. Two RPA operators were interviewed to identify factors that impact workload in target tracking missions. Performance, subjective workload, cortical, cardiac and eye data were collected. One cardiac and several eye measures were sensitive to changes in workload as evidenced by performance and subjective workload data. Potential future applications of this research include closed loop systems that employ advanced augmentation strategies, such as adaptive automation. Thus, by identifying physiological measures well suited for …
