The following datasheets are filled with example data for a hypothetical airport. Specific data formats will generally depend on the requirements and needs for the particular noise modelling system as well as the study scenario.\nNote:\nIt is recommended that geographic information (reference points etc.) be specified in Cartesian coordinates. The choice of the particular coordinate system usually depends on the maps available.\nA1\nGENERAL AIRPORT DATA\nA2\nRUNWAY DESCRIPTION\nFor displaced thresholds, runway description may be repeated or displaced thresholds can be described in the ground track description section.\nA3\nGROUND TRACK DESCRIPTION\nIn the absence of radar data the following information is needed to describe particular ground tracks.\nA4\nAIR TRAFFIC DESCRIPTION\nA5\nFLIGHT PROCEDURE DATA SHEET\nExample aircraft for a Chapter 3 Boeing 727-200 as derived from radar using the guidance set out in Section 2.7.9 of the main text.\nExample for a procedural profile based on A/C-data stored in ANP database:",
