# BLs (Bestemmelser for Luftfart)

BLs (Instructions for Airtraffic) is the law document for flying in Denmark instructing how to fly. It is a gathering of law documents that sets the required standards for pilots, however it is identical to ATC rules, and hence a great source of learning the correct rules.

BLs will tell you:

- Rules concerning flying
- General laws concerning controlling, such as airspace, clearances, etc.
- General approved Phraseology

ATS Instructions will NOT tell you:

- Local regulations
- Tips and tricks
- Anything VATSIM related
- Controller specific rules

There are many of these documents so we have done you a favor and included the relevant ones and highlighted all that is considered relevant for VATSIM.

The documents should be studied as you are waiting to commence Pre-Training (1st Stage). Later once you start training the Pre-Training course will reference these documents from time to time.
