  • Pilot’s Willingness to Operate in Unmanned Aircraft System Integrated Airspace

    PI Lakshmi Vempati

    PI Scott Winter

    The interest in Unmanned Aircraft Systems (UAS) use for private, civil, and commercial purposes such as package delivery, inspection, surveillance, and passenger and cargo transport has gained considerable momentum. As UAS infiltrate the National Airspace System (NAS), there is a need to not only develop viable, safe, and secure solutions for the co-existence of manned and unmanned aircraft, but also determine public acceptance and pilot’s willingness to operate an aircraft in such an integrated environment. Currently there is little or no research on pilot’s perceptions on their willingness to operate an aircraft in UAS integrated airspace and airports.



    The purpose of this study was to determine what effect the type of UAS integration, the type of UAS operations, and the airspace classification will have on pilot’s perspectives and willingness to operate an aircraft in UAS integrated airspace and airport environment. This study surveyed the eligible pilot population in hypothetical scenarios using convenience sampling to measure their willingness to operate an aircraft in UAS integrated airspace and airports using the Willingness to Pilot an Aircraft Scale, which has been shown to be valid and reliable by Rice, Winter, Capps, Trombley, Robbins, and Milner (2020). A mixed factorial design was used to study the interaction effects between the independent variables and the effects on the dependent variable, i.e., willingness to pilot an aircraft.

    The results of the mixed analysis of variance (ANOVA) indicated a significant interaction between type of UAS integration and airspace classification. Overall willingness decreased with airspace and differences in willingness to pilot an aircraft were based on segregated and integrated operations. The average pilot’s willingness to pilot an aircraft score differed from the highest score being for Class B, decreasing with decreasing airspace classes, with the lowest being for Class G.

    Analysis of pilot perspectives collected through open ended questions using text-mining techniques showed agreement with mixed ANOVA analysis that the primary factor in the pilot’s perception was airspace. Key concerns voiced by the pilots were situation awareness, risk and safety of operations, aircraft certification and airworthiness, and operator experience and regulatory conformance. The most positive sentiment was observed among pilots presented with the hypothetical scenario of fully autonomous UAS operations in a segregated environment. Findings from the study could aid regulators in developing better policies, procedures, integration solutions, improved training, and knowledge sharing.

  • Developing Artifact Peer Review Assignment Methodologies to Maximize the Value of Peer Review for Students

    PI Matthew Verleger

    This engineering education research project seeks to develop a proof-of-concept peer review matching algorithm and demonstrate if it is a valuable and viable methodology for conducting peer review. Peer review is a proven method that has positive impact on student learning. The project will test the algorithm on Model Eliciting Activities in the engineering classroom, and investigate how changing peer review can affect student learning.



    ​The broader significance and importance of this project is the transformative potential of improving peer review processes, since peer review is used throughout STEM and medical fields. Thus this preliminary investigation can extend outside the realm of improving student learning. This project overlaps with NSF's strategic goals of transforming the frontiers through preparation of an engineering workforce with new capabilities and expertise. Additionally NSF's goal of innovating for society is enabled by supporting the development of innovative learning systems.

  • Platform for Investigating Concept Networks on the Instrumentality of Knowledge (PICNIK)

    PI Matthew Verleger

    This engineering education research project seeks to develop a concept network for engineering and a platform for helping students identify how concepts are connected across a curriculum.  The goal is to better understand and improve how students value the concepts being taught throughout their education.



    By data mining course materials (i.e., textbooks, course notes, syllabi, video transcripts, websites, etc.), a concept network can be developed for that course. With each additional resource, the network connectedness become more fully representative.  By mapping materials from courses throughout a curriculum, and then overlaying the resulting map on a degree plan of study, students will be able to better identify and value how concepts being taught today are connected and used throughout the rest of their education. For instructors, curricular redesign becomes significantly easier, as they will be able to more fully contextualize how other courses depend on their material.

  • Bayesian Analysis of Stellar Evolution

    PI Theodore von Hippel

    Bayesian Analysis of Stellar Evolution is an international collaboration studying stellar evolution with an emphasis on stellar ages. We also develop and support a Bayesian software suite that recovers star cluster and stellar parameters from photometry, currently called BASE-9.

    BASE-9 is useful for analyzing single-age, single-metallicity star clusters, binaries, or single stars, and for simulating such systems. BASE9 uses Markov chain Monte Carlo to estimate the posterior probability distribution for the age, metallicity, distance modulus, and line-of-sight absorption for a cluster, and for the mass, binary mass ratio, and cluster membership probability for every cluster member.

  • Optimizing Countermeasures for Spaceflight-Induced Deconditioning

    PI Christine Walck

    This research focuses on understanding space deconditioning and developing comprehensive systems to mitigate the adverse physiological effects of microgravity on astronauts.

    Spaceflight-induced deconditioning presents a major challenge to human health during and after long-duration missions, contributing to muscle atrophy, bone loss, cardiovascular dysfunction, and sensorimotor impairment. This research investigates the underlying mechanisms of physiological decline in microgravity and evaluates integrated mitigation strategies using a combination of ground-based analogs (e.g., head-down tilt, LBNP), biomechanical modeling, and real-time physiological monitoring. By developing a modular countermeasure system — featuring tools like the Lower Extremity Force Acquisition System (LEFAS) and personalized exercise protocols — we aim to preserve musculoskeletal and cardiovascular integrity throughout space missions. The findings contribute to NASA’s broader efforts in preparing astronauts for lunar and Mars exploration.

  • Small UAS (sUAS) Mid-Air Collision (MAC) Likelihood

    PI Ryan Wallace

    CO-I Dothang Truong

    CO-I Scott Winter

    CO-I David Cross

    This research focuses on sUAS MAC likelihood analysis with general aviation (GA) and commercial aircraft. Because severity research varies based on where a collision occurred on a manned aircraft, this likelihood research will not only look at the probability of a MAC, but also the likelihood of colliding with different parts of a manned aircraft.

    Complete Mid-Air Collision (MAC) risk assessments require estimates of both collision severity and collision likelihood. This research focuses on sUAS MAC likelihood analysis with General Aviation (GA) and commercial aircraft. Because severity research varies based on where a collision occurred on a manned aircraft, this likelihood research will not only look at the probability of MAC but also the likelihood of colliding with different parts of a manned aircraft.

  • Best practices in teaching statistics and research methods within an aviation curriculum

    PI Robert Walton

    Student learning assessment is necessary at most universities, the question is whether or not student learning assessment though the use of tests can be turned into a less anxiety-provoking experience and, most ideally, into a summative learning experience for students. Using a three-test format student assessment this research examined an alternate testing paradigm, aiming directly at anxiety associated with tests and grades.



    This research will examine an alternate testing paradigm, aiming directly at anxiety associated with tests and grades. The research question for this study is whether or not student assessment though the use of a traditional testing format could be made less anxiety provoking and, most ideally, be turned into a teaching/learning experience for students. Students in a statistics course will be assessed using a three-test format. Tests will be scored immediately after completion, with the student present and incorrect responses explained. The student can then retake an alternate exam and will receive the highest grade on any version of the test they take. Data will be examined for statistically-significant indicators from version 1, to 2, to 3 of the examinations.

  • Air Traffic Controllers’ Occupational Stress and Performance in the Future Air Traffic Management

    PI Hui Wang

    CO-I Edward Mummert

    As demand for unmanned aerial vehicle (UAV) operations increases, it is vital to understand its effects on air traffic controllers and the safety of the national airspace system. This study’s primary purpose is to determine how UAVs that operate in controlled airspace would influence air traffic controllers’ occupational stress and performance. In a within-subject experimental research design, 24 participants sampled from a university’s undergraduate Air Traffic Management (ATM) program completed three different air traffic control (ATC) scenarios on an en-route ATC simulation system. The degree of UAV automation and control were varied in each scenario. The participants’ stress levels, performance, and workload were measured with both objective and subjective measurements. Within-subjects ANOVA tests showed significant effects on the participants’ stress level, performance, and workload when automated UAVs were present in the scenario. Participants experienced increased workload, the highest level of stress, and carried out the worst performance when with controllable UAVs in the airspace. These findings can inform UAV integration into controlled airspace and future research into UAV automation and control and ATC management.

  • Safety Systems, Culture, and Passengers’ Willingness to Fly in Autonomous Air Taxis

    PI Kenneth Ward

    CO-I Scott Winter

    As city populations grow, the transportation industry plans to alleviate traffic congestion by introducing the urban air mobility (UAM) concept, in which small passenger and cargo aircraft augment metropolitan transportation networks. A key component of UAM is that of air taxis, which are on-demand air services for individuals and small groups. In addition, UAM companies are designing the aircraft to operate fully autonomously: The intent is for the vehicles to arrive and transport people from point to point without input from human pilots.



    In studies of passengers’ perceptions, researchers found that safety was among the top passenger concerns. The international market complicates the matter, as research indicates people from different nations differ in their willingness to fly in autonomous aircraft. Past research hypothesized that individuals’ cultural orientation, specifically their degree of individualism or communalism, was a factor of the differences in willingness to fly.

    A quantitative survey experiment in two studies was conducted to investigate willingness to fly in autonomous air taxis among people from the United States and India. The first study used a 2 x 2 x 2 factorial analysis to test the effects of nationality, automatic airframe parachute availability, and remote pilot system availability on willingness to fly. People from India were more willing to fly than people from the United States, and people in general were more willing to fly in an aircraft equipped with an automatic airframe parachute. The second study replicated the effects of the first and tested whether two aspects of cultural orientation mediated the relationship between safety system availability and willingness to fly. Cultural orientation was not found to significantly mediate the relationship among people from the United States or India.

  • Navigation and Control for Autonomous Vessels

    PI Darris White

    PI Eric Coyle

    PI Patrick Currier

    Development of closed-form solution for control of over-actuated maritime systems.

    A method for controlling the position, orientation and velocity of a marine vessel in a body of water with multiple, independently steered propulsion devices. The method involves receiving a command to move to a specific position and orientation. Utilizing position/heading feedback control, a control algorithm is used to calculate the required forces and moments to move the vehicle. Steering angles and thrust forces are determined for each of the vessel's propulsion devices. The thrust and angular displacement limits of each device are used to determine if the required forces and moments are achievable using one of three modes of operation: parallel steer, counter steer and combined parallel/counter steer. The approach fully utilizes the solution workspace for the over-actuated system without requiring the use of an optimization. The approach is used for smooth autonomous navigation in scenarios that include station keeping, path following, transitional states, disturbance rejection and object avoidance.
