EUROCAE has produced a number of deliverables in the SWIM area, including but not limited to a SWIM Service specification on an information service for AMAN extended Horizon, a template for future service standardisation within EUROCAE and a list of potential SWIM Services to be standardised. The role of EUROCAE WG-104 is to provide EUROCAE working groups with even more reliable and useful support material in form of an improved template and a comprehensive methodology to accomplish their SWIM Service standardisation activities. It is envisaged that the outcome produced will be immediately useable in the European SWIM context.
