Weather is responsible for approximately 70% of air transportation delays in the National Airspace System, and delays resulting from convective weather alone cost airlines and passengers millions of dollars each year due to delays that could be avoided. This research sought to establish relationships between environmental variables and airport efficiency estimates by data mining archived weather and airport performance data at ten geographically and climatologically different airports. Several meaningful relationships were discovered from six out of ten airports using various machine learning methods within an overarching data mining protocol, and the developed models were tested using historical data.

This research investigates the antecedents of airline travel intention, including the effects of crisis management, service quality perceptions, and loyalty programs, along with the fear of coronavirus disease (COVID-19) and risk attitude among individuals from different parts of the world during the peak of the pandemic. Its main objective is to assess how these variables impact passenger airline travel intention. Partial least squares structural equation modeling was used to assess the measurement model and test the hypothesized relationships on the sample of 944 travelers. Results indicated strong positive associations between fear of COVID-19, risk-averse attitudes, and service quality with respect …

The objective of this Research Project was to study the possible benefits of developing an improved Metering Control System. This study identified potential cost savings and reduced emissions through the greater use of a Metering Control System. The results of this research have indicated an annual cost reduction of $720,000 in fuel burn and a significant delay time reduction caused by accumulated ground traffic. In addition, during peak hours, it was concluded that savings could be potentially higher. Therefore, by optimizing the ground movement, it is also expected a lower level of CO2 emissions, an increased safety level due to …

The coronavirus crisis effects on aviation in 2020 are currently well-documented. Nonetheless, the widely registered low traffic due to the crisis does not necessarily lead to increased air navigation efficiency. Thus, the present work, developed to fulfill the program outcomes for the Master of Science in Aeronautics, Air Traffic Management (ATM) specialization, aimed to investigate what was the impact of the COVID-19 crisis on air navigation efficiency in Brazil. This research question was addressed through a quantitative, nonexperimental, observational approach with two parallel branches, designed to answer two sub-questions.

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 …

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 …

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 …

Aircraft maintenance is a fundamental and necessary element in any aviation operation. In order to be considered safe and airworthy, operators must be diligent in the way aircraft are maintained and how employees are performing. A safety management system (SMS) is an organized approach by management to include every employee of a company that standardizes the procedures a company will follow to improve safety. The structure of SMS was designed by the International Civil Aviation Organization in order to be standardized across different countries and types of operations. Currently, only part 121 U.S. commercial airlines are mandated by the Federal …

Human error has been well studied in aviation. However, less is known about the ways in which human performance maintains and contributes to aviation safety. The lack of data on positive human performance prevents consideration of the full range of human behaviors when making safety and risk management decisions. The concept of resilient performance provides a framework to understand and classify positive human behaviors. Through interviews with commercial airline pilots, this study examined routine airline operations to evaluate the concept of resilient performance and to develop a taxonomy for success. The four enablers of resilient performance, anticipation, learning, responding, and …

Airline daily departures, not including private aircraft, increased from 25,143 in 2000 to 36,722 in 2017. More passengers necessitate more aircraft and more flights. With more aircraft at terminals, ground delays, based on current airport design, will continue to increase. Systems that allow for reduced aircraft time on the ground will improve airline economics and airport operations, in addition, will reduce airline delays both for departure and arrival at the gate. The purpose of this qualitative research study was to explore the efficacy, from ramp controllers’ perspectives, of equipping airliners with an electric taxi system. Prototype electric taxi systems have …

During the last decade, commercial aviation in Brazil has grown significantly, overcoming the number of 100 million passengers per year. The full operation represents a challenge for the air carriers, especially during flight disruptions. Besides the re-accommodation of the passengers into other flights, under certain circumstances, the ANAC 400 resolution requires the airlines to provide a series of material assistance. Meal, transport, and hotel make part of the exigences stated by the ANAC 400. Our study aims to analyze the current process that is mainly manual and propose to automatize several steps through a self-service solution. The researchers verified the …

The objective of this study is to propose a review of the operational restrictions imposed on Congonhas airport by IAC 121-1013, seeking a balance between flight safety and operational efficiency.
The researchers calculated the landing performance (using specific software), taking into account particular aircraft system failures that increase landing distance. The results indicated that the measures imposed by the IAC have little or no effect on the operational safety increase. Additionally, the restrictions created operational complexity for the airport and reduced its efficiency by impacting airline costs. At the end of the study, the researchers suggest a reissue of the …

Since 1987, the US Department of Transportation (DOT) has ordered US airlines to report baggage handling statistics. The Code of Federal Regulations (CFR), requests each U.S. carrier to report monthly the total number of passengers enplaned, and the total number of mishandled baggage reports (MBR), including lost, pilfered, damaged and delayed baggage. The U.S. DOT also created a mishandled-baggage rate, which represents the total number of MBRs divided by 1,000 passengers enplaned. This KPI is monthly published at the Air Travel Consumer Report. And it is used worldwide to make comparisons between regions, airports, and airlines, characterizing efficiency and consistency …
