Airspace Pre-Validation

Correct Airspace Data inconsistencies

The purpose of this Airspace pre-validation service is to allow ANSPs to detect and correct inconsistencies and/or incomplete fields in airspace data before publication.


‘Airspace Pre-Validation’ consists in implementing and validating airspace data before official publication of the Aeronautical Information Publication (AIP).


  • Several AIRAC cycles in advance, National ENV Coordinators (NECs) and/or Airspace Management Cell (AMC) may submit their planned airspace modifications to the Network Manager Operations Centre for pre-validation purposes.
  • In collaboration with the ENV Coordinator and or the AMC and the FMP specialists in the relevant ANSP, the Network Manager Operations Centre creates a specific database that is loaded on test systems. 
  • The ANSP team, including the ENV Coordinator and or the AMC and the FMP specialists, simulate the impact of the airspace/route structure changes using existing/adapted/newly created flight plans - in coordination with the Network Manager Operations Centre.
  • The simulation results are given to the ANSP/CNAA/State.
