Free Route Airspace (FRA). A specified airspace within which users may freely plan a route between a defined entry point and a defined exit point, with the possibility to route via intermediate (published or unpublished) waypoints, without reference to the ATS route network, subject to airspace availability. Within this airspace, flights remain subject to air traffic control.
South East Common Sky Initiative (SECSI). Initiative of several States/ANSPs on European Southeast Axis traffic flow to implement cross-border FRA.
South East Common Sky Initiative Free Route Airspace (SECSI FRA). The airspace volume consisting of airspace volumes defined in ENR 2.1 and/or ENR 2.2 of the corresponding AIP-s where cross-border application of FRA is implemented.
Cross-border application of FRA (in SECSI FRA). Application of FRA operations in a manner to allow crossing of inter and intra ATC units boundaries regardless of State or FIR boundaries, at any position, if not otherwise regulated via the RAD.
FRA Arrival Connecting Point (A). A published significant point to which FRA operations are allowed for arriving traffic to specific aerodromes. The FRA relevance of such points shall be included in ENR 4.1/ ENR 4.4, columns as (A). Indications on their use for arrivals to specific aerodromes shall be notified via the RAD.
FRA Departure Connecting Point (D). A published significant point from which FRA operations are allowed for departing traffic from specific aerodromes. The FRA relevance of such points shall be included in ENR 4.1/ENR 4.4, columns as (D). Indications on their use for departures from specific aerodromes shall be notified via the RAD.
FRA Horizontal Entry Point (E). A published significant point on the horizontal boundary of the Free Route Airspace from which FRA operations are allowed. The FRA relevance of such points shall be included in ENR 4.1/ ENR 4.4, columns as (E). If this point has specific conditions of utilization, this shall be described in the RAD.
FRA Horizontal Exit Point (X). A published significant point on the horizontal boundary of the Free Route Airspace to which FRA operations are allowed. The FRA relevance of such points shall be included in ENR 4.1/ ENR 4.4, columns as (X). If this point has specific conditions of utilization, this shall be described in the RAD.
FRA Intermediate Point (I). A published significant point or unpublished point, defined by geographical coordinates or by bearing and distance via which FRA operations are allowed. If published, the FRA relevance of such points shall be included in ENR 4.1/ ENR 4.4, columns as (I). If this point has specific conditions of utilization, this shall be described in the RAD.
DCT or Direct. DCT or Direct should be used only for flight planning purposes when submitting FPL, and when executing specified type of approach.
