DSA Quick Start Guide

Before consulting our quickstart guide, we highly suggest to visit the BCAA’s website explaining the new legislations. There you will find all legal requirements to correctly execute your flight, wherever you are in Belgium.

A special procedure is foreseen for operators performing missions as described in EU 2018/1139 art. 2 par. 3. Operators who believe they are eligble for this special procedure should contact the SPACC office on SPACC@skeyes.be

DSA tool: the essentials

The Drone Service Application (DSA) allows the easy submission of flight authorization requests within the UAS Geographical Zones managed by skeyes, in particular the Control Zones (CTRs) of Antwerpen, Brussels, Charleroi, Liège, Oostende, as well as the Kortrijk Radio Mandatory Zone (RMZ).

To allow for an efficient treatment of flight authorizations, these zones have been divided into multiple Very Low Level (VLL) zones, based the risk level towards manned aviation. More information about these zones is below.

Note that this tool can only be used for flight authorization requests within skeyes’ CTRs and Kortrijk RMZ. For more information about other published UAS Geographical Zones, visit https://map.droneguide.be

For information: certain types of drone operations will require an additional “operational authorization” from BCAA. Please consult the BCAA website for this (https://mobilit.belgium.be/fr/transport_aerien/drones).

UAS Geographical zones

These are the 6 GeoZones managed by skeyes for which you are legally obliged to use DSA to get a flight authorisation:

  • Five GeoZones situated around the airports of Antwerpen, Brussels, Charleroi, Liège and Oostende.

    They are subdivided in to 3 subzones called VLLs (“Very Low Level”- airspace)
    • VLL0: over and close to the actual runways
    • VLL1: above and near the airport
    • VLL2: further away from the airport
  • One GeoZones situated around the airports of Kortrijk (delimited by the Radio Mandatory Zone)

    It’s subdivided in to 2 subzones called VLLs (“Very Low Level”- airspace)
    • EBKT RMZ 1: above and near the airport
    • EBKT RMZ 2: further away from the airport

New process of requesting a flight authorization in skeyes airspace

Please note that the user will be guided through every step by the DSA tool, but it is expected of the operator/pilot to be aware of and understand these different steps.

For the DSA tool, there are two stages of a flight authorization request: pre-authorization and final authorization.

Pre-authorization (multiple days to multiple hours before the operation)

The pre-authorization consists of all prior strategic coordination with skeyes.

There are several steps during this phase. Please note that these steps will be automated within the DSA tool.

Planning your operation

If you would like to fly in skeyes airspace, you have to plan and submit your operation for review through the Drone Service Application.

Depending on which VLL you want to fly in, the request needs to be sent to skeyes some time in advance, due to the necessary treatment process (see the timeframes below).

VLL 0: No later than D-15
VLL 1: No later than D-8
EBKT1 No later than D-8
VLL 2: No later than H-3
EBKT2 No later than H-3

These timeframes are to ensure that skeyes and any additional stakeholders have sufficient time to review your flight authorization request.

Pre-authorization of your operation

Once reviewed, hopefully your operation has been given a pre-authorization. This indicates that all relevant partners are aware of your operation, and have agreed with it. Possibly, they have added additional restrictions or comments – please make sure to thoroughly read through the approved request.

Operation confirmation

If your operation takes place in VLL0/VLL1/RMZ1, you must confirm via the tool that you really intend to fly on that day. This can be done starting from 1 day before the planned start of the operation, and no later than 3 hours before the operation. This is necessary, so the Air Traffic Controller / Aerodrome Flight Information Officer can take into account your operation while planning.

If your operation takes place in VLL2/RMZ2, the confirmation will happen automatically, 3 hours before the start of your operation.

VLL 0: Not earlier than D-1
no later than H-3
VLL 1: Not earlier than D-1 and no later than H-3
EBKT1 Not earlier than D-1 and no later than H-3
VLL 2: Automatic at H-3
EBKT2 Automatic at H-3

Final (tactical) authorization (day of the operation)

This is the tactical coordination with skeyes, the day of the operation right before take-off. It is the final step before you can fly.

If your operation takes place in VLL0/VLL1, you must contact Air Traffic Control 30 minutes before the start of your operation by VHF radio or by telephone.

If your operation takes place in VLL2/RMZ1/RMZ2, contacting Air Traffic Control for authorization is not required. Authorization in these zones will be granted automatically. However, Air Traffic Control might contact you themselves in order to give you additional instructions.
