Aviation System Block Upgrade (ASBU) Implementation Monitoring Report

The ICAO Global Air Navigation Plan, (GANP) Aviation System Block Upgrades (ASBU) methodology is a programmatic and flexible global approach that allows all Member States to advance their Air Navigation capacities based on their specific operational requirements.

The Block Upgrades aim to enable aviation to realise the global harmonization, increased capacity, and improved environmental efficiency that modern air traffic growth now demands in every region around the world.

Member States, through the ASBUs framework, work with ICAO, their Air Navigation Service Providers and industry stakeholders to advance their air navigation capabilities and systems based on specific operational requirements and to implement them in a harmonised and timely fashion to maximise the capacity, safety and efficiency of air traffic.

This 7th version of the EUR ASBU implementation Monitoring Report includes the updated progress/status of implementation of ASBU Block 0 and 1 elements (reference period 2020) from 53 out of 55 States within the ICAO EUR Region and was endorsed at the EASPG/3 Meeting in December 2021. After the transition to the 6th edition of the ICAO Global Air Navigation Plan (GANP), the report now includes information on 70 out of 87 ASBU elements which had been proposed for monitoring.

Previous versions of the ASBU implementation monitoring report, which have been jointly developed by the 

ICAO EUR/NAT office and EUROCONTROL, can be found here:
