FRA - How to navigate through RAD

To find valid restrictions and rules, select relevant AIRAC (date) on RAD homepage.


RAD is always published D-34 before work efficiency.


You can see individual Annexes. Crucial for planning in FRA is Annex 2B. For Arrivals and Departures you also need to comply with Annex 3A. Flights through TMA Praha will have to file in accordance with RAD DCT structure, which is published in Annex 3B.

When you open certain part of RAD, in the Change Record column you can see, if the TFR (traffic flow rule) is NEW, AMD (amended) or DEL (deleted) for this AIRAC cycle. Always check Applicability or Availability, as some might be valid only during certain times.


Annex 2B: Local and Cross-border Capacity and Structural Rules

Annex 2B is in general utilizing usage of ATS routes, navigation points and airspaces . Most of FRA rules are coded for points, some for airspaces as a reference location.

Use filters in the first line. Suggested filters to effectively read in Annex 3B are:

- NAS/FAB (you can filter all Czech - LK TFRs),

- ID (you can find specific ID, for example if you get FPL rejected by certain TFR),

- Point or Airspace.



Annex 3A: Aerodrome Connectivity Options

Annex 3A is utilizing how certain STARs and SIDs can be used . FRA connecting route from SIDs to Departure (D) points and from Arrival (A) points to STARs is also coded here.

Use tab ARR if you are looking for arrival connectivity and tab DEP if you are looking for departure connectivity. In tab General AD Conditions general rules and AD DCT limits can be found. Use filters in the first line. Suggested filters to effectively read in Annex 3A are:

- ARR AD and DEP AD (you can find all utilized connectivities to/from certain airport - PRAGUE_GROUP contains LKPR/KB/VO),

- First PT STAR / STAR ID and Last PT SID / SID ID (you can find connectivities to / from specific points, where STAR begins / SID ends),

- ARR ID and DEP ID (you can find specific ID, for example if you get FPL rejected by certain TFR),

- NAS/FAB (you can filter all Czech - LK connectivities).



Annex 3B: Enroute DCT Options

Annex 3B is defining DCT planning outside of FRA limits, in the Czech Republic mostly in the TMA Praha.

In tab FRA-LIM DCT limits for each airspace can be found. In tab P2P plannable RAD DCT segments (longer than DCT limit) can be found. Use filters in the first line. Suggested filters to effectively read in Annex 3B are:

- ATC Unit (you can filter DCTs by ATC unit responsible for the Airspace, which these DCTs are crossing - LKPRAPP and LKAAACC),

- FROM (you can filter from where the DCT is plannable),

- TO (you can filter where to the DCT is plannable).

Always check Vertical Limits of the DCT and Utilization, as some might only be available to specific traffic.



Increment file

Increment file serves to publishing ad-hoc changes outside of the standard procedure (later than RAD publication date D-34). Increment file changes are usually composed into the RAD next AIRAC cycle. Be aware, that until then you can't see these changes in RAD, even though these might already be valid.


Use tabs at the bottom to navigate through changes of certain RAD parts. You can read Increment file the same, as standard RAD, but there are added columns with validity for every TFR. Those are:

- Date Valid FROM (the date, since when the restriction/rule is valid),

- Date Valid UNTIL (the date, untill when the restriction/rule will be valid),

- Release date (the date, when the restriction has been created/amended/deleted),

- Published in Annex .. (the AIRAC cycle, when the TFR will be published in RAD).
