Free Route Airspace (FRA) DCT Restrictions

FRA DCT Restrictions

FRA description is published in relevant AIP per State.
The FRA DCT Restrictions:
• Define rules for flying direct (DCT) in the Free Route Airspace (FRA);
• Have the same features as conventional DCT limitation restrictions, extended with the possibility to define the FRA Horizontal Entry/Exit points and the FRA Intermediate points;
• Are used to generate valid route/s in FRA.

The FRA DCT Restrictions xls file represents the CACD definition as published in State AIPs and provided and/or adapted by the National Environment Coordinators (NEC) in order to allow proper flight planning via relevant FRA area. The FRA DCT Restrictions xls file includes the following data:
• General: General description of FRA and cross-border FRA allowances or limitations and their applicability periods;
• Conditions: Description of conditions and vertical use of FRA and cross-border FRA allowances or limitations;
• Elements: Description of FRA Significant Points and additional FRA DCTs.

The FRA DCT Restrictions are coded in accordance with NM AURA Naming Convention for Restriction identifiers as follows:

• Origin ID:

- AUA/AUAG first 2 or 4 characters (Group ID: 100 - 499) - Country Code ID(s) (Group ID: 500).

• Group ID:

- 100 to 499 - Internal State / FAB / ANSP allowances or limitations for AUA / AUAG or relevant FRA Significant point.
Example: Lx100 - might represent either en-route FRA limitations with relevant vertical dimensions or vertical allowance of FRA Significant point or vertical allowance of additional FRA DCTs.

- 500 - Cross-border States / FABs / ANSPs allowances or limitations between AUAs / AUAGs or relevant border FRA Significant point. Example: LxLx or LxLy or LxLyLz - might represent either cross-border FRA limitations from / to with relevant vertical dimensions or vertical allowance of FRA Significant point or vertical allowance of additional FRA DCTs.

• Subgroud ID:

- A, B, C...: Expression of several "sub" Restrictions when required by allocating the same Origin ID, Group ID and different SubGroup ID.

Example: Vertical allowance of FRA Significant point (elements). LxLx500A expresses the vertical connectivity for "Arrivals" from the FRA (exiting the FRA from above). LxLx500D expresses the vertical connectivity for "Departures" to the FRA (entering the FRA from below).

Important General Notes:


1. When vertical dimensions of FRA Significant points are not presented they are by default in accordance with State AIS publications FRA area definition and relevant flight directions represented by the relevant ID.
2. Published FRA Intermediate points with different from FRA area vertical limits are presented in NMOC system as “EX” (considered as Vertical Entry / Exit allowed).
3. Abbreviations (RAS, FLR, CEL, etc.), different from those used in RAD, are based on “Airspace Data Operations Manual” and “Network Operations Handbook Provision of CACD data”.

The FRA DCT Restrictions are published once per AIRAC (AIRAC date).
