As a basic flexible use of airspace (FUA) principle, airspace should no longer be designated as military or civil but should be considered as a single continuum and used flexibly on a day-to-day basis. All users can have access, and on the basis of actual needs, their requests should be managed to achieve the most efficient use of airspace. Wherever possible, permanent airspace segregation should be avoided.
The FUA concept has evolved to become the advanced flexible use of airspace (AFUA) concept, which is expected to provide more flexibility on the basis of dynamic airspace management in all flight phases, from initial planning to execution.
AFUA is based on extended civil-military cooperation, more proactive, performance oriented to achieve mission effectiveness and flight efficiency.
AFUA is an airspace management concept, based on a civil – military partnership to enhance an efficient use of airspace. It is aimed at providing a responsive approach in a more complex environment within which traffic growth needs to be accommodated.
