Three key performance indicators are used to measure airport performance: passenger numbers, aircraft movements, and air cargo activity. The document analyzes these indicators for Paris Charles de Gaulle Airport using three years of historical data to develop forecasting models. These models accurately predict 2017 passenger numbers of 67,387,303, aircraft movements of 471,599, air cargo of 1,959,530 metric tons, and air mail of 180,388 metric tons, with expected growth rates ranging from -1.9% to 1.67%. However, the air cargo forecasting model has a lower accuracy due to a coefficient of determination of only 71.21%.
