Correct Delay Code Assignment, Alessandro Conconi, Anderson Da Silva Serafim, Vitor Cordeiro Silva, Thais Vieira Haberli

Graduate Student Works

The air transport market requires high investments, has elevated risks, and low financial return. The competition requires airlines to differentiate themselves by offering better services. On-time Performance (OTP) is an essential service; lack of punctuality affects company costs and revenues. An on-time company generates more satisfaction for travelers, retaining them. Flight delays are identified and reported by airlines through delay codes that are standardized by IATA.

A detailed and specific analysis of an airline's processes was performed to verify the quality of delay code allocation information. It also features the complete mapping of this company's delay code allocation processes and …

A Better Approach For Mishandled Bags Industry Measure, Ana Caroline Costa, Daniel B. Ravagnani, Domenico Giuseppe Valente, Vitor Coletti Fernandes

Graduate Student Works

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 …

Contingency Fuel Reduction, Diogo Youssef, Fabiano Gomes De Oliveira, Joao Centeno, Luciano Figueiredo Vale De Oliveira

Graduate Student Works

This project reviews the minimum fuel regulations for commercial passenger flights in different countries and intends to scientifically support a change in the existing contingency fuel requirement regulation in Brazil. This change represents fuel savings for Brazilian air operations, and it deploys into competitive advantage for Brazilian airlines compared to foreign air operators. The objective of this project is to provide the Brazilian civil aviation regulators with the necessary data to justify the reduction of the contingency fuel values from the current 10% to 5%. This project bases the analysis on the historical data of fuel planning and fuel consumption …

Automated Disruption Assistance, Christian Gruber Delamare, Douglas Cabrera Lopes, Patrice Ramos, Raioni De Oliveira Santos

Graduate Student Works

During the last decade, commercial aviation in Brazil has grown significantly, overcoming the number of 100 million passengers per year. The intense operation represents a challenge for the air carriers, especially during flight disruptions. In Brazil, 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 …

A Study On Spare Aircraft In Brazilian Airlines, Clarissa Pinheiro Pereira, Eduardo Sakashita, Eliudes Del Grande, Guilherme Bevilacqua

Graduate Student Works

All around the globe, the airlines struggle to sustain profitability. They are deeply affected by the region’s economy. It goes from the fuel price and exchange rate to the level of employment and average salary. That makes it imperative to control the cost, and also to balance very well the cost and level of service. Aircraft utilization is one KPI that measures productivity. Once the airline has a high aircraft utilization, it means that the resource has been productive, hence more cost-efficient.

On the other hand, flight cancelations and delays result in costs and passengers’ dissatisfaction. In Brazil, there is …

An Evaluation Of The Operational Restrictions Imposed To Congonhas Airport By Iac 121-1013, Glanski O.C. Pacheco Jr., Marcus Camargo

Graduate Student Works

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 …

Training Synergy, Andre Vieira Caputo, Everton Amieiro, Lucio De Araujo Alves, Renan Dapena Roveran

Graduate Student Works

Brazil is facing a growth in the airline industry where all the major airlines are currently hiring pilots, flight attendants, and mechanics. One of the challenges of those airlines is to provide training for all these professionals. Many times they do not have instructors or classrooms available. It is crucial for the airlines to promote faster and better training, to reduce cost, save time and resources to prepare a better professional. With this capstone, we want to show the possibility of increasing the cost performance of airline training by providing alternatives to airlines. The idea is to promote synergy between …

Engine Light Repair Shop Evaluation For A Brazilian Airline, Gustavo Henrique Melhado Trevilatto, Marcelo Teodoro Miranda

Graduate Student Works

The maintenance cost of a commercial aircraft comprises airframe, components, and engines. The most expensive of them are engines, which may represent up to 60% of an aircraft cost, and therefore will have a significant impact on any airline finance. As a result, engine fleet maintenance management is crucial for any airline sustainability. Apart from heavy maintenance where life limited parts are replaced and its performance restored, aircraft engines are often required to come off wing for light repair due to operational issues like foreign object damage, high oil consumption, and vibration issues. In other cases, even though being operational, …
