Airspace pre-validation allows Air Navigation Service Providers (ANSPs) to detect and correct inconsistencies and/or incomplete fields in airspace data before official publication of the Aeronautical Information Publication (AIP) or major events.

The pre-validation procedure begins several AIRAC cycles in advance, when National Environment (ENV) Coordinators (NECs) and/or Airspace Management Cell (AMC) may submit their planned airspace modifications to the Network Manager Operations Centre (NMOC) for pre-validation purposes. The Operations Centre then creates a specific database that is loaded on test systems, in collaboration with the NEC, the AMC and the Flow Management Position (FMP) specialists in the relevant ANSP. This allows the ANSP team to simulate the impact of the airspace/route structure changes using existing, adapted, or newly created flight plans. This work is coordinated with the NMOC and is performed in collaboration with the NEC, AMC and the FMP specialists.
