At the ANI/WG/2 Meeting (June 2015), an Ad hoc Group was formed to discuss the metrics of the ASBU Block 0 implementation status, performance reporting and revisions to the ANRF which will be used by States and Territories in the NAM/CAR regions. In the ANI/WG/2 report, this Ad hoc group was named ANRF Ad hoc group.


At the ANI/WG/3 Meeting (Apr 2016), the delegates agreed on a more active participation from the States/ANSP to reflect their national priorities and users' main needs, and therefore agreed to create an ad hoc group to support review, follow-up and reporting on the achievement of the air navigation (AN) targets established in the NAM/CAR Regional Performance-Based Air Navigation Implementation Plan (RPBANIP) and in the Port-of-Spain Declaration. During ANI/WG/3, this ad hoc Group was named ASBU Ad Hoc Group.


At the NACC/WG/5 Meeting (May 2017), the delegates agreed that the ASBU Ad Hoc Group would become the ANI/WG ASBU Task Force (TF), to assist the region in the implementation of harmonized technologies that supports the operation, their given tasks are:


Develop effective methods to determine the regional implementation status of the ASBU block-0 elements and the performance monitoring of the Regional Air Navigation System, on a cyclical annual basis, as a regional input to the Annual Global Air Navigation Report and feedback for the Global Air Navigation Plan and the Regional Dashboard.


Assist NACC's States to formulate or update their National Air Navigation Plans by using a planning process to ensure alignment with the RPBANIP and the GANP.


Contribute with the continuous updating of the RPBANIP in order to maintain the validity, accuracy, and applicability of the Plan.
