Route availability coordination and implementation consists of the collation, coordination, validation and publication of a single-source flight-planning document. It integrates both structural and ATFCM requirements, geographically and vertically, following an appropriate collaborative decision making (CDM) process between the Network Manager and operational stakeholders.

This enables ANSPs to define restrictions and thus prevent disruption to the organised system of major traffic flows which go through congested areas. They can do so while at the same time following aircraft operators’ requirements. This helps to maximise capacity and reduce complexity.

For more info about the procedure, consult the ERNIP PART4 Route Availability Document (RAD) Users Manual.


  • Route Availability Document (RAD) - a central source of airspace utilisation rules and availability defined and communicated by the ANSPs, coordinated 56 days and published 28 days in advance of the start of the relevant Aeronautical Information Regulation and Control (AIRAC) cycle. Production of the RAD involves data compilation, interpretation, validation, and implementation in the CACD database. This document is available via the NOP Portal in the RAD Portlet.
