The Post Ops Performance Adjustment Process allows operational stakeholders to notify national and European authorities of issues that relate to ATFM delay measurement, classification and assignment.
It is a means of enhancing operational ATFM delay data used in the performance scheme (Regulation (EU) 390) – and thus a means of compliance with Article 21(3). Implementing the adjustment process will provide a better understanding of network constraints and it should encourage more positive network behaviour and innovative procedures.
