The purpose of this report is to illustrate to airfield and airport authorities the need for timely, accurate information regarding actual or planned changes to the physical airfield, recognize the changes in regulatory requirements in flight training, specifically visual database elements used in simulation, identify critical data elements for designing visual databases, and describe the elements and their uses in a simulated training environment. The list and descriptions of required visual database data elements will provide guidance to airfield and airport authorities and suppliers of data regarding minimum levels of data required to accurately create and maintain a visual representation of an airfield or other aircraft operating area. The report will also be used to provide information from airfield operators and managers concerning physical changes or additions to runways, taxiways, land-side gates, and the surrounding area.
