Project number

Short description
Eurocontrol's SESAR and FAA's NextGen program see textual NOTAMs (Notices to airmen) be replaced by Digital NOTAMs in Aeronautical Information Management of the future. This project will exploit and extend semantic technologies for fine-grained, intelligent filtering and querying of Digital NOTAMs, using a wide range of criteria based on event types, types of aircraft or flight, as well as location in space and progress in time.
