3.1.2 Flexible Airspace Structures
3.1.2.1 The FUA Concept uses airspace structures that are particularly suited for temporary allocation and/or utilisation.
3.1.2.2 The different airspace structures; Conditional Routes (CDRs), Temporary Segregated Areas, (TSAs), Temporary Reserved Areas (TRAs), Cross-Border Areas (CBAs) or those Danger or Restricted Areas (D, R) subject to pre-tactical or tactical allocation under the Temporary Airspace Allocation (TAA) process, as well as Reduced Co-ordination Airspace (RCA) or Prior Co-ordination Airspace (PCA) procedures used for flexible airspace management are detailed hereafter.
3.1.2.3 In addition the present Section 3 provides elements for the information on any other activities of particular nature or for re-shaping the airspace to accommodate user-preferred trajectories for vectoring and in the future, free routing and/or autonomous operations.
3.1.3 National High-Level Policy Body Functions
3.1.3.1 In accordance with FUA principles, Strategic ASM at Level 1 consists of a joint civil and military process, within the high-level civil/military national body which formulates the national ASM policy and carries out the necessary strategic planning work, taking into account national and international airspace users requirements.
3.1.3.2 The permanent "National High-Level Policy Body" is required to establish a joint civil and military process to perform the following minimum functions:
Edition: 2.0 Released Issue Page 3-1
a) formulate the national policy for airspace management;
b) reassess periodically the national airspace structures including ATS routes (see Section 4) and Terminal Airspace (see Section 5) with the aim of planning, as far as possible, for flexible airspace structures and procedures;
c) validate activities requiring airspace segregation and assess the level of risk for other airspace users;
d) plan the establishment of flexible airspace arrangements (CDRs, TSAs, CBAs, RCAs, PCAs, .. ) and conduct, if required, associated safety assessment;
e) change or modify, if required and if practicable, Danger and Restricted Areas into temporary allocated airspace;
f) establish controlled airspace and ATS airspace classifications (see Section 2) taking into account the FUA concept;
g) publish in national AIP the airspace structures including ATS routes and ATS airspace under its jurisdiction;
h) co-ordinate major events planned long before the day of operation, such as large scale military exercises, which require additional segregated or reserved airspace, and notify these activities by AIS-publication;
i) periodically review the national airspace needs and, where applicable, cross-border airspace utilisation.
