Remote Pilot Situational Awareness With Augmented Reality Glasses: An Observational Field Study, Jeffery Coleman, David Thirtyacre

International Journal of Aviation, Aeronautics, and Aerospace

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. …

Predictability Improvement Of Scheduled Flights Departure Time Variation Using Supervised Machine Learning, Deepudev Sahadevan, Palanisamy Ponnusamy Dr, Manjunath K. Nelli Mr, Varun P. Gopi Dr

International Journal of Aviation, Aeronautics, and Aerospace

The departure time uncertainty exacerbates the inaccuracy of arrival time estimation and demand for arrival slots, particularly for movements to capacity constrained airports. The Estimated Take-Off Time (ETOT) or Estimated Departure Time(ETD) for each individual flight is currently derived from Air Traffic Flow Management System (ATFMS), which are solely determined based on individual flight plan Estimated Off Block Time(EOBT) or subsequent delays updated by Airline. Even if normal weather conditions prevail, aircraft departure times will differ from ETOTs determined by the ATFMS due to a number of factors such as congestion, early/delayed inbound flight (linked flights), reactionary delays and air …

Helicopter Shaft Heating Parameters For Polyamide-11 Coating, Selim Kevran Ph.D, Uğur Ati̇ci̇

International Journal of Aviation, Aeronautics, and Aerospace

In this study, the heating parameters required for polyamide-11 (P11) coating of the helicopter shaft were investigated. The torsion value created by the force applied to the middle of the helicopter's shaft is measured. Heating before coating affects the torsion value of the shaft. A new heating mechanism has been designed to cover the shaft surface without changing the torsion value of the shaft. Thus, the coating surface is left inside the furnace and the torsion measurement area outside of the furnace. Taguchi method was used to determine heating parameters such as furnace type, initial temperature and heating time. The …

MCT is known as Minimum Connection Time. It refers to the time needed for a passenger to connect from a flight to another in a specific airport, varying according to the connection type. MCT is an essential tool for airlines. It is used as an input in constructing their network and daily, specifically by operational teams, to connect or disconnect a passenger from a flight, for example, during an IROPS scenario. However, the MCT is considered the worst scenario of the variables that composes it, which means that there are opportunities for airlines to reduce the connection time in daily …

In-Flight Fuel Management Committing To The Destination, Aldo Bien, Daniel Araguaia Galli Ribas, Paulo Cesar Serafim Pacheco, Rodrigo Garcia De Freitas Cardoso

Graduate Student Works

This project intends to clarify the Brazilian Civil Aviation Regulation RBAC 121 on its topic relating to the current ICAO recommendation from Doc. 9976 (Flight Planning and Fuel Management Manual), which regards the committing to the destination policy.

The present Brazilian regulation is not precise whether the alternate fuel could or could not be used to proceed to the original destination without compromising the emergency fuel, once exact specific requirements are met. As a result of unclear directrices, each major airline in Brazil comprehends and applies the ICAO recommendation in its way. Such a non-standardized interpretation of the current …

Parking Effects On Aircraft Reliability And Flight Performance, Danilo Scolfaro Fava, Fabio Renato Rossi Do Nascimento, Lucas Serrano Rodrigues, Rafael Gustavo Shoiti Yamashiro

Graduate Student Works

During the pandemic period caused by Coronavirus (COVID-19) in 2020, the airlines have parked or stored their fleets partially or wholly worldwide. The International Air Transport Association (IATA) estimated a major downsize in approximately 65% of the worldwide airline fleet's airline operational activity at the end of April 2020. With that said, mechanical and electrical systems, when stopped during long periods, can deteriorate by corrosion, contamination, discharge, and oxidation (Boeing, 1998). During the aircraft parking or storage process, it is not different (Airbus, 2020). This study aims to understand how much the aircraft performance and reliability are affected by parking …

Modeling Land And Hold Short Operations: Balancing Safety And Arrival Rate, Kenneth A. Ward, Heather Owen-Perry

Journal of Aviation Technology and Engineering

Many airports conduct simultaneous operations on intersecting runways to increase the rate of takeoffs and landings. This requires landing aircraft to hold short of the intersecting runway, which incurs a safety risk of runway incursions in the process. A Monte Carlo simulation was conducted to analyze the traffic load at maximum operational capacity at Charlotte-Douglas International Airport in order to analyze the fleet types and the rate of those landing aircraft unable to stop short of the intersecting runway. The researchers used the actual and four alternative compositions of the subject airline’s aircraft arrivals, interspersed among other airport traffic, to …
