  • The Constructivist Approach towards Identifying the Challenges of ESP
           Teachers: The Case of Aviation English

    • Authors: Gökhan Demirdöken Mr.
      Abstract: Continuous growth of aviation industry necessitates developing a better understanding of English for Specific Purposes teaching settings to improve the quality teaching and in turn, to serve best for the needs of ESP students. Therefore, role of ESP teachers and their experiences in these teaching settings need to be closely monitored for improved professional development opportunities. Taking this into account the present study focused on ESP teachers working and giving Aviation English courses in a tertiary level institution in Turkey. The constructivist approach was adopted to uncover the challenges encountered by ESP teachers in the target setting. Five ESP teachers were observed for a 45-minute period by the researcher to become familiar with their in-class practices. Then, semi-structured interviews were conducted with participants by asking them to reflect on their in-class practices to develop a better understanding of their instructional challenges. The findings of this qualitative study revealed that (1) low self-efficacy and low contextual knowledge were the most prominent challenges of ESP teachers and that (2) lack of professional development programs and inexperience in ESP teaching were the underlying reasons for those challenges. In this sense, the present study offered important insights into ESP teachers’ long-neglected yet crucial instructional challenges.

  • Aerodynamic characterization of bio-mimicked pleated dragonfly aerofoil

    • Authors: Md Akhtar Khan et al.
      Abstract: The work inspired by the dragonfly wing corrugation positioned at the front wing's radius section lying at 40% of the total wingspan of forewing from the root section. During gliding flight, dragonfly wings presumed to be an ultra-light aerofoil due to its well-defined cross-sectional corrugation. The aerodynamic simulation carried out to understand the aerodynamic performance of a bio-mimetic dragonfly corrugated airfoil at low Reynolds number range of 75000-150000 to explore the potential advantages of pleated airfoils at a varying angle of attack from 0° to 12°. CFD analysis accomplished by using ANSYS Fluent to understand the aerodynamic performance of the pleated aerofoil and its counterpart profiled aerofoil. The simulation result exhibits aerodynamic commission, i.e. the corrugated aerofoil's gliding ratio (CL/CD), is higher than that of a profiled aerofoil. The analysis demonstrates that the pleated corrugated aerofoil produces a comparable higher lift coefficient than that of profiled aerofoil NACA 0015 and reduces the separation bubble. The vortices trapped inside the valleys, which re-energize the flow and delay flow separation leads to an increment in lift coefficient (CL). These investigations amplify the demand of insect-inspired corrugated wing structure and make a possible application for improved design of pretended wings for micro air vehicles.

  • Identification of Wind-Induced Hazard Zones Impacting UAS Bridge
           Inspection

    • Authors: Jack J. Green et al.
      Abstract: Unmanned Aerial Systems (UAS) continue to grow in both popularity and utility within the national airspace system. The use of commercial UAS for civil inspection, specifically that of bridge structures, is becoming commonplace among practitioners and academics alike. The development of an integrated bridge-inspection hazard model provides a way for UAS operators to prepare for and respond to changing environmental conditions that could otherwise prevent a successful UAS flight. The interaction of wind-induced airflow with bridge surfaces creates an aerodynamic wake that can result in hazardous conditions for a UAS platform operating in close proximity. An analysis of this airflow surrounding an overpass bridge using computational fluid dynamic (CFD) models shows where these hazardous areas exist, based on initial wind conditions, existing functionality of UAS platforms, and mitigating systems that exist within current UAS technology. Altering the initial conditions by modifying wind velocities allows for a baseline understanding of which areas surrounding an overpass bridge structure are not suitable for successful UAS flight. Hazard zones range from severe, moderate, and mild, to no appreciable hazard. Moderate to extreme hazard zones are located in areas where high levels of wind shear, vorticity, or general turbulence exist, making UAS operations difficult. This study develops a practical model that may be utilized by UAS operators to better understand and potentially avoid unsafe flight environments during bridge structure inspections.

  • Leveraging Aircraft Transponder Signals for Measuring Aircraft Fleet Mix
           at Non-Towered Airports

    • Authors: Chuyang Yang et al.
      Abstract: The general aviation sector has contributed significantly to the overall growth of the aviation industry. Fleet mix and operations information is important for the analysis of both the safety and the environmental and economic impact of general aviation activity. Factual data on the impact of environment and safety is particularly important, given the scarcity of airport improvement funds and the strong stakeholder engagement that often occurs when airport investments are evaluated. The research presented herein evaluates Mode S short and extended squitter data collected from three general aviation airports over a one-month period. This article demonstrates that by utilizing the unique ICAO code present in Mode S records in the United States, ICAO identification can be used as a primary key for retrieving information from publicly available databases, permitting the determination of aircraft type and engine models. An aircraft operation type with the corresponding fleet mix information can thus be estimated at non-towered airports. The techniques reported here are also useful in monitoring the increase in aircraft compliant with the FAA’s January 1, 2020 mandate for ADS-B out to operate in large portions of the national airspace system. For the three Indiana airports studied, the proportion of ADS-B transponder messages received ranged from approximately 29% at the Terre Haute Regional Airport (KHUF) to 79% at the Purdue University Airport (KLAF).

  • Pilot Visual Detection of Small Unmanned Aircraft on Final Approach during
           Nighttime Conditions

    • Authors: Jon M. Loffi et al.
      Abstract: In December 2020, the Federal Aviation Administration (FAA) announced the release of a new final rule, permitting operators of small unmanned aircraft systems (sUAS) to perform routine night operations. Public comments to the Notice of Proposed Rulemaking indicated potential safety concerns regarding a pilot’s ability to spot a low-altitude sUAS during nighttime conditions. Leveraging data from the FAA’s UAS Sighting Report Database, the research team evaluated the significance of aircraft encounters with UAS at night. Researchers conducted an inflight experiment in which 10 pilots performed an instrument approach to airport during nighttime conditions in which a multi-rotor sUAS presented a potential collision hazard. The sUAS was equipped with lighting visible for 3 miles with a sufficient flash rate to avoid a collision, as specified by the new regulation. Participants performed five approaches, with the sUAS flying different scripted encounter profiles. Participants were asked to indicate when they visually spotted the sUAS, with sighting data recorded via an onboard observer. Geolocation information from both the aircraft and sUAS were compared at the time of each reported sighting to assess visibility distance and orientation. The sUAS was successfully spotted during 30 percent (n = 12) of the testing passes. Hovering sUAS were spotted at the same rate as moving sUAS, however, sUAS in motion were spotted at a much greater range. Researchers noted disproportionately higher spotting rates occurred when the sUAS was oriented on the starboard side of the aircraft vs. the port side. It is believed that airport lighting systems may have obscured or otherwise camouflaged portside sUAS encounters. When asked to estimate distance to an encountered sUAS, most participants underestimated, perceiving the sUAS to be much closer than reality. Additionally, the researchers assessed the potential for the participants to initiate evasive maneuvers, based on the distance and closure rate of the aircraft and sUAS at the time of sighting. Based on the FAA’s Aircraft Identification and Reaction Time Chart, collision avoidance would only have been successful during 15 percent of encounters (n = 6). The research team recommends Remote Pilots employ vigilant traffic awareness during nighttime operations, and leverage use of ADS-B (In) technology and monitor Common Traffic Advisory Frequencies to maintain situational awareness—particularly when operating in proximity to airports.

  • AERODYNAMIC PERFORMANCE ANALYSIS OF CO-FLOW JET AIRFOIL

    • Authors: C M Vigneswaran et al.
      Abstract: The work in this paper aims to increase the maximum lift coefficient of the airfoil by implementing the co-flow jet concept on NACA 0018 airfoil and also to investigate the performance of co-flow jet (CFJ) airfoil. To conduct numerical solution, RANS equations have been solved for 2D incompressible and unsteady flow using the Spalart-Allmaras turbulence model. The suction surface of the airfoil is modified by placing the injection slot near the leading edge and the suction slot near the trailing edge. A small mass of air is withdrawn into the airfoil suction slot, pressurized by a pumping system located inside the airfoil, and re-injecting into the injection slot tangentially to the main stream flow. The CFJ airfoil is enhancing the aerodynamic lift coefficient significantly compare to the baseline airfoil. And also, the numerical analysis is carried out to investigate the effect of the location of injection and suction slot. And it is observed that the aerodynamic lift coefficient of CFJ airfoil is increasing with varying the injection slot away from the leading edge.

  • Support to Design for Air Traffic Management: An Approach with Agent-Based
           Modelling and Evolutionary Search

    • Authors: Gabriella Gigante et al.
      Abstract: This paper presents a methodology to manage the support to design in ATM operations. We propose a workflow for the design of ATM solutions in a performance-based setting. The methodology includes the evaluation of the impact on human behaviour and exploits a combination of different paradigms, such as Agent-Based Modelling and Simulation, and Agent-Based Evolutionary Search. We prove the soundness of the methodology by carrying out a real case study, which is the transition from Direct Routing to Free Routing in the Italian airspace. The validation results exhibit limited errors for the assessment of the performance metrics under evaluation. Furthermore, the optimization of sector collapsing/decollapsing configuration is discussed to demonstrate the effectiveness of the implemented engines.

  • Quantum Safety Metrics Framework for Commercial Unmanned Aircraft
           Operators

    • Authors: Tracy L. Lamb et al.
      Abstract: Commercial unmanned aircraft systems continue to increase in applications and diversity; however, mishaps and accidents erode safety, investment return, and efficiency. Most unmanned aircraft accidents are preceded by leading indicators; the ability to forecast and quantify these may provide increased safety and profitability. This mixed-method research study used a non-experimental parallel convergence approach with multiple instruments, multiple-case study n = 22, and one exemplar case design to develop a quantum safety metric program. This study used a combination of previously validated methods as development instruments, including; the HFACS, STAMP, 'Sierra Scale,' and Accident Prevention Effort equations. The study extended the Accident Prevention Effort and Sierra Scale equation to determine quantum safety metrics at the time of an accident, and enable benchmark accident prevention values. This new quantum safety metrics program for small commercial unmanned aircraft operators may be replicated and applied to specific types of operating environments, for predictive and optimal safety performance.

  • Comparative Study on the Prediction of Aerodynamic Characteristics of Mini
           - Unmanned Aerial Vehicle with Turbulence Models

    • Authors: Somashekar V et al.
      Abstract: When dealing with CFD simulations the turbulent nature is seen on most of the engineering flows and these flows need to be solved. Reliable and applicable CFD outputs can be obtained from the accurate modelling of the turbulence as it is one of the most vital elements of CFD modelling. The RANS equations are extensively employed to analyse the complex flows over aircraft and for this purpose, a turbulence model is needed for turbulent flow analyses. Compatible turbulence must be chosen for the exact predictions of aircraft aerodynamic characteristics. In this report, numerical analyses of Mini-UAV are done to compare the outputs of different types of turbulence models for the prediction of aircraft aerodynamic characteristics for various flight conditions i.e., -4° to 40° at Mach number 0.04. ANSYS software is employed for this aerodynamic analysis. The six turbulence models compared are the Spalart-Allmaras, k-ɛ standard, k-ɛ RNG, k-ɛ Realizable, k-ω standard, and k-ω SST model. The impact of several turbulence models on the Mini-UAV aerodynamic performance is also studied numerically and validated with existing experimental data from reliable sources. The lift and drag coefficients for both numerical and experimental results exhibit an excellent correlation at Mach number 0.04. The recorded maximum variation of the coefficient of lift and the lift-to-drag ratio is determined to be 9.43% at a stall angle of attack (38°) and 7.01% at a 4˚ angle of attack among the six various turbulence models. The summation of deviation of coefficients of lift and drag values i.e., 0.0166 for the Spalart-Allmaras turbulence model is found to be less compared with all the other turbulence models so it can be said that the Spalart-Allmaras turbulence model is the best fit in terms of coefficients of lift and drag for Mini-UAV applications for subsonic flow.

  • A Model for Inhalation of Infectious Aerosol Contaminants in an Aircraft
           Passenger Cabin

    • Authors: Bert A. Silich
      Abstract: Aerosol contamination of an aircraft cabin by infectious passengers is a concern of passengers, aircrew and the aviation industry. This may be especially important during a pandemic, such as COVID-19, where the full extent of aerosol transmission is not well understood. A statistical method to determine the number of infectious passengers on board along with a mathematical model estimating the contaminant concentration of aerosols in the cabin and the number of inhaled infectious particles by passengers is presented. An example is used to demonstrated how the results can be estimated during normal operations and emergency conditions with malfunctions of the air conditioning and pressurization system which are responsible maintaining clean cabin air. This type of information can assist the aviation industry in providing the end users of aircraft travel, i.e. passengers and aircrew, with reasonable cabin contaminant guidelines. Accomplishing this in a timely manner requires the combination of modeling adjusted by experimentation. Physically testing all aircraft for each of these conditions would be time consuming, expensive and impractical. Incorporating a model towards solving these problems can serve to bridge the gaps between a finite number of experimental results.

  • Emotional Intelligence and Safety Citizenship among Army aviators

    • Authors: Zachary T. Dugger et al.
      Abstract: The purpose of this study was to develop an understanding of the relationship between trait emotional intelligence and safety citizenship among United States Army aviators. The study includes analysis of survey responses from 29 individual aviators. Regression analysis was performed to evaluate the relationship between safety citizenship, emotional intelligence, and 15 emotional intelligence facets. Results indicate a significant association (F(1,28) = 15.45; p = 0.001) between safety citizenship and emotional intelligence, and between safety citizenship and 3 emotional intelligence facets: Adaptability (F(1,25) = 23.91; p < 0.001), Self Esteem (F(1,25) = 10.75; p = 0.003), and Optimism (F(1,25) = 8.71; p = 0.007). Increased Adaptability and Self Esteem can increase safety citizenship behaviors among aviators. Training and selection of Army aviators with these traits could result in safer air travel and possibly reduced human factor-related aviation incidents.

  • The Determination of the Factors Affecting Air Transportation Passenger
           Numbers

    • Authors: Tüzün Tolga İNAN Asst. Prof. Dr. et al.
      Abstract: So long as human beings are required to go between places, the civil aviation industry will always exist. In this study, a country-based examination has been applied to air passenger numbers. 50 countries are selected according to the highest rating of air transportation passenger numbers, gross domestic product (GDP), total population, and human development index (HDI) data. 28 of these countries are included in the analysis which is common in at least three of these rankings. The relationship between the four parameters is examined via correlation analysis. Thereafter, the related parameters were taken as independent variables in multiple linear regression analyses to determine the factors affecting passenger numbers. The results show that GDP and HDI plays a significant role in passenger numbers. Based on these significant relationships, dimension reduction is done by explanatory factor analysis mapping countries clearly. Exploring the similarities of countries, multidimensional scaling (MDS) is used. The best countries using passenger transportation are found as the United States, the United Kingdom, Brazil, and Turkey via MDS configuration. Except for the United States, the reason these countries are found as the best according to passenger transportation is related to their geographical location which is not stated with the numbers.

  • Remote Pilot Situational Awareness with Augmented Reality Glasses: An
           Observational Field Study

    • Authors: Jeffery Coleman et al.
      Abstract: With the use of small unmanned aerial systems (sUAS) proliferating throughout industry and public safety, it is imperative to ensure safety of flight. The Federal Aviation Administration (FAA) published regulations for commercial use of sUAS in 2016 and included the requirement to maintain visual line-of-sight with the aircraft at all times. However, due to the nature of the sUAS ground control stations (GCS), remote pilots time-share between observing the aircraft and interacting with the display on the GCS. Time-sharing between the aircraft and GCS can be seen as similar to the cross-check a pilot uses when flying a manned aircraft. While manned aircraft designers have invested in the ergonomics and understanding of the cognitive process to optimize situational awareness, it has not been a design requirement for sUAS. The result is that the unmanned operator must change head orientation, eye focus, and remove the aircraft from peripheral vision during the cross-check between the GCS and aircraft. This, coupled with the limited field of view of the sUAS GCS displayed camera, leads to loss of situational awareness through task saturation, and misprioritization. Mixed reality, virtual reality, and augmented reality visual devices are being adopted in the gaming and technical world. The application of these devices to the sUAS GCS could mitigate some of the degradation of situational awareness. Specifically, the incorporation of augmented reality devices where a synthetic display is overlaid on the real-world, allows the remote pilot to observe the aircraft, manipulate the camera, and interact with the GCS without changing head position. This participant observational study evaluated the difference between the remote pilot cross-check while flying with a typical GCS display and when flying with an augmented reality headset in a field setting. The results indicate a significant difference between the pilot’s crosscheck when using augmented reality glasses allowing the pilot to maintain the aircraft in their field of view 56.7% of the time compared to 20.5% when not using the glasses.

  • Folding Methodology for Flexible Aircraft Interiors

    • Authors: Aditya Venkatesh et al.
      Abstract: This paper establishes a general furniture folding methodology that is aimed at flexible aircraft cabin interiors. This methodology will allow users to modify existing furniture pieces to their liking and thereby customizing their overall travel experience. The folding methodology also includes a process to quantify the transformation of the furniture pieces. This paper also introduces two design concepts called Open-on-Demand and Reconfiguration to allow passengers to modify an otherwise rigid cabin. The advantages of the multi-functional space saving furniture pieces are also illustrated in this paper. While the general folding methodology was developed for aircraft interiors, it can be adapted for any furniture piece positioned within any environment.

  • Real-Time Urban Weather Observations for Urban Air Mobility

    • Authors: Kevin A. Adkins et al.
      Abstract: Cities of the future will have to overcome congestion, air pollution and increasing infrastructure cost while moving more people and goods smoothly, efficiently and in an eco-friendly manner. Urban air mobility (UAM) is expected to be an integral component of achieving this new type of city. This is a new environment for sustained aviation operations. The heterogeneity of the urban fabric and the roughness elements within it create a unique environment where flight conditions can change frequently across very short distances. UAM vehicles with their lower mass, more limited thrust and slower speeds are especially sensitive to these conditions. Since traditional aviation weather products for observations and forecasts at an airport on the outskirts of a metropolitan area do not translate well to the urban environment, weather data for low-altitude urban airspace is needed and will be particularly critical for unlocking the full potential of UAM. To help address this need, crowdsourced weather data from sources prevalent in urban areas offer the opportunity to create dense meteorological observation networks in support of UAM. This paper considers a variety of potential observational sources and proposes a cyber-physical system architecture, including an incentive-based crowdsensing application, which empowers UAM weather forecasting and operations.

  • Prediction of Gate In Time of Scheduled Flights and Schedule Conformance
           using Machine Learning-based Algorithms

    • Authors: DEEPUDEV SAHADEVAN et al.
      Abstract: Prediction of Gate to Gate block time for scheduled flights is considered as one of the challenging tasks in Air Traffic Flow Management (ATFM)system. Establishing an effective and practically reliable model to manage the problem of block time variation is a significant work. The airlines do tend to pad or inflate block time to Actual Block time to calculate Schedule block times which is approved by aviation regulator. This will lead to flaws in air traffic flow strategic decision-making and in turn affect the efficiency, estimation and undesirable delays, which leads to traffic congestion and inefficient ground delay programs. This study evaluates the effectiveness of nonlinear and time varying regression models to predict block time with minimal attributes in order to solve the problem of difficulty in predicting the block time variation. The key research outcome of this paper is to trace the temporal variations of flying time for different aircraft types and to predict the variation of actual arrival time from the scheduled arrival time at the destination airport. Ultimately, a combination of M5P regression model and logistic regression model is proposed to predict early, delayed and on-time conformity with approved schedules. Analysis based on a realistic data set of a domestic airport pair (Mumbai International Airport and New Delhi International Airport) in India shows that the proposed model is able to predict in block time at the time of departure with an accuracy of minutes for of test instances. As a result of the scheduled arrival time performance (early, delayed and timely) has been classified accurately using Logistic regression Classifier of machine learning. The test results show that the proposed model uses a minimum number of attributes and less computational time to more accurately predict the actual arrival time and scheduled arrival performance without details on the weather.
