Belgian airspace can be quite challenging to understand if you’re not familiar with it. A daily airspace file is published in the morning: you can make it visible on http://mids.be/notam/bpc/bpc.php and /or load it into your flight instrument so to help you keep out of forbidden airspace during your XC flight. A Facebook page has been created if you have questions: https://www.facebook.com/groups/BPCup/
CAUTION :Although the airspace file is checked daily, you are still the only responsible for your XC flight. The use of the airspace file is only offered as an aid.
