CANSO’s goal is to help ANSPs provide services that are technically interoperable, procedurally harmonised, universally safe, and affordable. The purpose of this document is to highlight critical areas for improvement, as well as to recognise initiatives and services that are working well. Reaching a full seamless set of global services is an evolutionary process. In order to maximise the impact of ANSP changes, our objective is to identify areas where investment funds will bring the best operational improvements. In other words, we will attempt to pinpoint the specific areas where the next steps on the seamless airspace evolution should take place.
