The Impact of COVID 19 on the Aviation Fuel Supply Chain in the Face of Changes in Air Traffic Service: Case Study of one of the Polish Airports

Purpose: Establishing the relationship between the decrease in air traffic and the volume of aviation fuel supplies in the context of Covid-19pandemic. Design/Methodology/Approach: To establish the relationship between the number of flight operations and the volume of fuel delivered to an airport, the best method is to determine the Pearson coefficient. The use of this coefficient is the most appropriate choice, as the correlation (interdependence of features) concerns the mutual relations between the number of air operations and the volume of aviation fuel deliveries to the airport [l]. Moreover, by analyzing the relationship between these variables by the correlation method, we obtain data in relation to the direction (trend) and the strength of the linear relationship, the impact of air traffic on fuel supplies to aircraft performing air operations. Findings: The analysis of the data presented in the paper shows an increase in the strength of the relationship between the number of air operations performed and the volume of fuel deliveries in the pandemic period, compared to the period before the pandemic. Practical Implications: The presented solutions may contribute to the optimization of fuel supply chain management in the aviation sector. Originality/Value: The originality of the text is related to the innovative application of correlation analysis to optimize the management of fuel supply chains.
