ABSTRACT
This chapter analyses the studies of the National Bank. Case studies such as this provide insight into how countries apply methodologies to measure economic impact of aviation and hence might be used as inputs for similar studies in other countries. The multiplier for value added equals 1.81, implying that 1 of value added generated directly by companies operating in air transport or airport activities generates 1.81 via the intersectoral links between these companies and companies upstream and downstream in the air transport value chain. Therefore, in order to put the studies by the NBB in perspective, this section will focus on analysing the noise impact of the largest airport in Belgium, Brussels Airport. Total value added by air transport and airport activities in Belgium amounted to more than 6 billion in 2015, growing at an annual average rate of 7.5 per cent between 2013 and 2015.
