Facility Rating Assignments (FRA)

You are here

What is it ?

An FRA or Facility Rating Assignment is a minimum criterion for ATC on a certain controller position.
This means that the ATC (the air traffic controller or IVAO member) needs to have a specific grade (or on IVAO called "rating") before he/she can take a certain ATC position.
You can find an overview of all existing ratings here.

As an example: an air traffic controller with an AS2 rating is not allowed to control EBBR_APP.

The purpose of these FRA's is not to discourage new members or ATC applicants from starting as an Air Traffic Controller, but to make sure that our pilots get good ATC quality and that all rules, guidelines and practices are respected to the maximum. The saying "Better bad ATC than no ATC" is not applicable to our FIR...
In any way, you should only open an ATC position with sufficiënt knowledge of the position concerned!


The number of registered IVAO-users is increased to over 25.000, and we have several hundreds of users online every day.
The efforts of the IVAO Training Department and the introduction of the exams have caused a giant leap in both ATC- and Pilots quality within our community.
We think now is the time to increase the overall online quality by the careful introduction and implementation the "Facility Rating Assignments" system" (FRA).
Carefully, because we have mixed interests. On the one hand we like to improve the overall quality of IVAO, on the other hand we do not want to discourage new and unexperienced users by raising the treshold too much.
Taking the above into consideration we have compiled the following quidelines for FRA's.


You might notice that there are less ATC positions available here on IVAO than in real life.
This is because we don't have the same traffic- and workload as in real life, so having all those real life positions here on IVAO would make it more complicated, more difficult to handle and less interesting to control.

In Belgium the Flight Information Service unit (FIS/FSS) will only be activated on the occasion of (intensive) VFR traffic activity, like with an event or during training sessions.

Be advised that this will mean a necessity to have studied the procedures and phraseology on forehand.

Some ATC positions are only available for events or training. This is indicated on the below overview.

EBBR Split Positions

Note that in real life there are multiple split ATC positions. These are :

Brussels ground
- Brussels ground North (EBBR_N_GND) on 118.050
- Brussels ground South (EBBR_S_GND) on 121.875 (when no split position allowed, log on as EBBR_GND)
The ground responsabilities can be find here (source: Belgocontrol).

Brussels tower
- Brussels tower North (EBBR_N_TWR) on 120.775
- Brussels tower South (EBBR_S_TWR) on 118.600 (when no split position allowed, log on as EBBR_TWR)
The tower responsabilities can be seen as an imaginairy line between RWY 25R and 25L, crossing the whole control zone in half from the Northeast to the Southwest. Note that other setups and divisions in the responsability are possible and used in real life. This is almost never used on IVAO. If used, the necessary information will be provided prior the event/training.

Brussels approach/departure
- Brussels approach (EBBR_APP) on 118.250 (also called "arrival")
- Brussels departure (EBBR_DEP) on 126.625
- Brussels final (never used on IVAO!)

You should only use the positions indicated above in bold. (you can ommit the "S" when logging in as EBBR_TWR or EBBR_GND).
Also have a look at the ATC quickviews.
The use of the split positions is not allowed unless there is prior approval from BE-ATC-OPS (BE-AOC and BE-AOAC). This can be the case for events or training.

FRA Overview


Remember R&R 5.1.2:

- Controllers must be familiar with the procedures of the airspace they want to control, if not, an IVAO™ supervisor or administrator could ask them to leave the position
