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 …

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 …

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 …

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 …
