Description
This research covers the possibility of airports serving as virus scanning hubs for future intercontinental travels. This aims at providing an idea for better control of tackling potential harmful viruses unknowingly carried by travelers. The benefit of this research is to help prevent less blow to the local economy and businesses, help keep travel industries, especially airlines, operating, slow down the rate of infection, and decrease cases and death rates, by providing a more secure health check for incoming and outgoing air travelers.

Description
This report summarizes the development of a lifting body aircraft configuration, referred to as ‘LBA’, aimed to serve the long-haul airliner market. This study was conducted in response to the aerospace industry’s goal to reduce global aviation’s emissions by 2050, as well as considered market potential. The report covers the preliminary sizing and design considerations for the LBA as well as practical testing against current conventionally configured long haul aircraft, specifically the Boeing 787-9 and Airbus A330-900 NEO. To test the effectiveness of a lifting body configuration, the wind tunnel at Arizona State University was used to compare models of the LBA, A330, and 787. The result quality from the wind tunnel was constrained due to its limitations and challenges to accurately scale Reynolds Number to that of a transonic regime. This renders the data with low fidelity, and therefore rather insufficient. However, the observed trends are promising and could rationalize expanded research into the application of a lifting body fuselage to improve aircraft efficiency.

Description
The primary purpose of this study is to evaluate the current state of affairs regarding regulatory compliance and passenger safety aboard commercial aircraft. Throughout the broad scope of the number of unique airline operations throughout the United States and the world, special consideration is given in order to ensure that passengers are both safe inflight and prepared for contingencies that can arise. The continued safety of passengers and crew members is the highest priority in every operational scope within the aviation industry. The process through which passenger awareness of safety is achieved, specifically during 14 CFR Part 121 and Part 135 commercial airline operations, is executed through the performance of live safety demonstrations by flight attendants, presentation of operator-developed videos, and the provision of printed safety cards to passengers who are encouraged (and in some cases legally required) to view them. Through the analysis of data derived from a newly distributed research study, current passenger attitudes towards safety and regulatory compliance onboard commercial aircraft will be measured and weaknesses identified. This research will leverage this data to identify and defend possible methods to improve the quality of airline passenger safety awareness and regulatory compliance procedures. Identified improvements involve inquiry into the relationships created between flight crewmembers and passengers, and also include potential modifications to procedural components such as emergency exit row briefings.

Description
Since the mid-2000s, the domestic aviation industry has been influenced by new, rapidly growing ultra low-cost carriers (ULCCs) such as Allegiant Air, Spirit Airlines, and Frontier Airlines. These carriers augment the existing low-cost airline model by operating largely point-to-point routes with a minimum of passenger amenities. Existing literature, however, is limited for North American ULCCs, often lumping them together with mainstream low-cost carriers. The pattern of markets served by ULCCs is incongruous with the models of other airlines and requires further research to examine causal factors. This paper sought to establish conclusions about ULCCs and the relevant market factors used for airport choice decisions.The relationship between ULCC operations and airport choice factors was analyzed using three methods: a collection of 2019 flight data to establish existing conditions and statistics, two regression analyses to evaluate airport market variables, and three case studies examining distinct scenarios through qualitative interviews with airport managers. ULCC enplanement data was assembled for every domestic airport offering scheduled ULCC service in 2019. Independent variable data informed by previous research were collected for every Part 139 airport in the U.S. The first regression analysis estimated a OLS regression model to analyze the log of enplanements. The second model estimated a binary logistic equation for ULCC service as a 0-1 dependent variable. Case studies for Bellingham, Washington, Waco, Texas, and Lincoln, Nebraska were selected based on compelling airport factors and relevant ULCC experience.
Results of the research methods confirm certain theories regarding ULCC airport choice, but left others unanswered. Maps of enplanements and market share revealed concentrations of ULCC operations on the East Coast. Each regression analysis showed a strong and positive relationship between population figures and the existence and quantity of ULCC operations. Tourism employment was only significantly related to enplanements. Other factors including distance and competition variables were significantly associated to ULCC service. Case studies revealed the importance of airport fees and costs in ULCC decision-making; factors that proved difficult to investigate quantitatively in this research. Further research may shed light on this complex and ever- changing subset of the domestic commercial aviation industry.
