Concept

The basis for the Flexible Use of Airspace Concept is that airspace is no longer designated as either "military" or "civil" airspace but is considered as one continuum and used flexibly on a day-to-day basis. Consequently, any necessary airspace segregation is only of a temporary nature.

The FUA Concept increases the flexibility of airspace use and provides Air Traffic Management (ATM) with the potential to increase the capacity of the air traffic system. The FUA Concept allows the maximum joint use of airspace. The FUA Concept also ensures, through the daily allocation of flexible airspace structures, that any necessary segregation of airspace is based on real usage within a specific time period.

Effective application of the FUA Concept requires the establishment in each of the European Civil Aviation Conference (ECAC) States of a national High-Level Airspace Policy Body. This body is tasked with the re-assessment of national airspace, the progressive establishment of new flexible airspace structures and the introduction of procedures for the allocation of these airspace structures on a day-by-day basis.

The practical application of the FUA Concept relies on national Airspace Management Cells (AMCs) for the daily allocation and promulgation of flexible airspace structures in the Airspace Use Plan (AUP), and on the Centralised Airspace Data Function (CADF) for the dissemination to aircraft operators of the daily availability of non-permanent Air Traffic Services (ATS) routes by the Conditional Route Availability Message (CRAM).

The States should also establish real-time civil/military co-ordination facilities and procedures to fully exploit the FUA Concept.
