Aspects of airline crew rostering
(University of Zilina, 2021) Le Duc, Manh; Badánik, Benedikt
Airline crew rostering is a complicated planning-type problem, and its objective is to assemble pairings into schedules that maximise the satisfaction levels of crews. The rostering process focuses on achieving a more balanced workload distribution among the crewmembers that allows designing rosters in the interest of the crew. The main purpose of the paper was to explain the fundamental aspects of airline crew rostering and its impact on crewmembers’ fatigue. Additionally, the research identified mitigation measures that airlines should make to combat or mitigate crewmembers’ fatigue when designing their rosters. The paper also allowed readers to understand the effects of fatigue on crew’s alertness and performance. The qualitative research methods (such as literature review) was used to understand the complexity of the airline crew rostering, the flight and duty time limitations, crew’s rest requirement and crewmembers’ fatigue. The survey was used as the quantitative research method to identify crewmembers’ satisfaction with their rosters that would help to optimise the rostering process. An online survey (using Google Forms) was distributed to potential respondents (experienced crewmembers) via email addresses and online platforms. Respondents were asked 18 close ended questions divided into two parts (demographic and operational experience). One hundred eleven responses were gathered, which showed that age plays a crucial role in crewmembers’ fatigue. In addition, cargo pilots are usually more dissatisfied with their rosters due to exhausting flight duty periods at nights.
Optimisation of turboprop aircraft operations as a means to reduce their environmental footprint
(University of Zilina, 2021) Števárová, Lucia; Badánik, Benedikt
This paper deals with the subject of optimisation of turboprop aircraft operations to decrease their environmental footprint. This aircraft category is not at the forefront of optimisation efforts of operators as it supplies lower volumes of traffic and is equipped with the most fuel-efficient technology for missions served on regional markets. The theoretical part of this paper details turboprop aircraft contributions to global CO2 emissions and analyses aspects behind their efficient performance. Further, it provides a thorough assessment of the operational practices that can significantly reduce the environmental footprint of turboprop aircraft operations. For better illustration, some are exemplified in simple case studies. The practical part of this work aimed to quantify the effects of operational optimisation on turboprop aircraft. Based on the theoretical analysis, we established five operational adjustments whose effects can be determined using performance calculations. These calculations have been carried out using ATR 72-600 aircraft as a reference for a specified average turboprop flight. It was found that through operational adjustments, the fuel consumption on an average ATR 72-600 flight can be decreased on the order of 10%. The energy intensity of operations defined in CO2 per revenue passenger kilometre could be nearly halved compared to actual values of the ATR 72-600 fleet.
Quality of service at airports
(University of Zilina, 2021) Proft, Branislav; Badánik, Benedikt
At present, air transport is on the rise and with it are the airlines, airports and services they provide. Their quality is reflected in revenues as well as in the number of airlines using the airport. The aim of this paper is to evaluate what services are offered to individual airport customers, how to evaluate customer satisfaction with services and the last chapter focuses on evaluating the quality of services offered to airlines and crew, where a method of evaluating services provided by airports from the airlines based on an analysis of current ways of measuring the quality of these services. Finally, possible service improvements are described, which could streamline the operation of the airport.
