Authors:Flavio A.C. Mendonca, Julius Keller, Chenyu Huang Pages: 51 - 64 Abstract: Purpose: Aircraft accidents due to wildlife hazards have become a growing safety and economic problem to the Brazilian and international aviation industries. These safety occurrences have resulted in significant direct and indirect economic losses as well injuries and fatalities worldwide. The purpose of this study was to develop empirical information obtained from the analysis of wildlife strike and aircraft operations data in Brazil that could be used for accident prevention efforts.Design/methodology: The research team collected and analyzed aircraft operations as well as wildlife strike data from the 32 busiest commercial airports in Brazil, from 2011 through 2018. Researchers obtained the number of aircraft operations at each of those 32 Brazilian airports from the Brazilian air traffic operations annual reports published by the Air Traffic Control Department. Wildlife strike data from the studied airports were obtained from the Brazilian national wildlife strike database. Descriptive data analysis was adopted to provide an intuitive and overall trend of wildlife strikes at and the 32 busiest commercial airports in Brazil.Findings: Results indicate that the number of wildlife strikes at and around the investigated airports increased 70% even though the number of aircraft operations at these airports declined by 12% during the period studied. Birds were involved in 88% of the reported events. Most reported strikes (59%) and damaging strikes (39%) occurred during the arrival phases-of-flight. Most (33%) strikes were reported by airport personnel. A finding of concern was that the majority of wildlife strikes (97%) and damaging wildlife strikes (96%) occurred within the airport environment.Originality/value: The current project contributes to the safety management of wildlife hazards in Brazil by conducting a comprehensive analysis of wildlife strike and aircraft operations data (2011-2018) in the 32 busiest Brazilian commercial airports.

Authors:Pedro Oliveira, Jorge Silva, Paulo Soares Pages: 65 - 75 Abstract: Purpose: The article aims to show the viability of installing a precision-based approach system in Viseu airfield, in Portugal. This work looks to evidence to what extent the implementation of ILS (Instrument Landing System) or GBAS (Ground Based Augmentation System) in the airfield is viable, and which of the two would be the better option for this case, from a technical and economic view and as a way to increase safety levels.Design/methodology/approach: The article analyses the airfield’s evolution over time and forecasts its movements for the future, over a 10-year period, by utilising two different models: multiple linear regression and IATA traffic forecasts. The different types of airfield taxes were also reviewed and their values were estimated for the following years. The equipment’s technical aspects and individual prices were analysed to accurately determine the time needed for the airfield to recover the investment done, allied with an 80% funding European project.Findings: Approach systems are being modernized, and throughout the years more airports and airfields are starting to replace old approach systems for satellite-based new ones. When compared to ILS, GBAS offers more advantages at a technical and economic level, and even for smaller airfields with a low traffic volume, sometimes it can be technically and economically possible to have such systems implemented.Originality/value: Studies about the implementation of new radio aids are usually prepared for big airports by airport operators or ANSPs before major investment projects. However, for most small regional airports in the country, where traffic is not near as big, such studies don’t exist, and for that reason, investigating the possibility of installing such kind of equipment is very important, especially taking into consideration the safety they provide and other benefits that naturally come up with it.

Authors:Elif Bolat, Savaş S. Ateş Pages: 77 - 86 Abstract: Purpose: The number of passengers, luggage, and cargo served at the airports increases at certain times due to flight density (peak hours). Due to the long queues at check-in desk during peak hours, there may be delays in flight operation processes. In addition, it is estimated that check-in queue times will increase even more in accordance with Covid-19 social distance rules.The aim of the study is to calculate the possible effects of Covid-19 measures on check-in queues at small-scale airports. For this purpose, the number of check-in desks that should be opened at peak hours was evaluated by simulation method at Erkilet airport.Design/methodology/approach: In the first part of the study, the effects of Covid-19 measures on the aviation industry and airport management issues are presented with the literature research. Information about Erkilet airport was collected by using qualitative research method and the intensity experienced during peak hours was simulated in the ARENA-TRIAL simulation program. Two 3D scenarios were prepared, including the pre and past COVID-19 social distance constraints.Findings: In the analysis section of the research, check-in queue times and staff productivity were calculated for both scenarios. In the calculations, comments were made regarding the problems that may occur during the peak hours of the airport within the scope of the check-in desk and COVID-19 social distance constraints. Based on the analysis outputs of the simulation program, recommendations were made for small-scale airports.Originality/value: The effect of COVID-19 on the check-in process in small-scale airports was examined for the first time with simulation method.
