Statens Luftfartsvæsen was Denmark’s former civil aviation authority, commonly abbreviated to SLV. The name still appears in historical records, aviation documents and older references, but it is no longer the name of a separate active authority. On 1 November 2010, SLV merged with Trafikstyrelsen.
Understanding that change makes searches much easier. A document bearing the Statens Luftfartsvæsen name may be useful for historical research, while someone seeking today’s aviation services needs the current authority’s website. This guide explains the background, key dates and practical difference.
What Was Statens Luftfartsvæsen?
Statens Luftfartsvæsen was a Danish government aviation body. Its history included safety supervision and the administration of aviation requirements, alongside air-navigation functions within its historical organisation.
It was not an airline, booking service or travel agency. The distinction matters because an authority sets or administers requirements within its remit, while airlines operate flights and airports provide infrastructure for those flights.
Denmark’s historical aviation overview traces the organisation’s roots to Luftfartsdirektoratet, established on 1 March 1938. The name Statens Luftfartsvæsen dates from 1985.
Statens Luftfartsvæsen Timeline
| Date | Institutional milestone |
|---|---|
| 1 March 1938 | Luftfartsdirektoratet established |
| 1985 | Statens Luftfartsvæsen name introduced |
| 27 October 2010 | Merger announced by the transport ministry |
| 1 November 2010 | Merger with Trafikstyrelsen took effect |
These dates describe institutional changes. They do not mean that every aviation rule changed on the same day, or that every service followed an identical administrative path. For a particular document, its own publication date and subsequent amendments remain important.

What Responsibilities Did SLV Have?
The historical account describes two significant areas: Luftfartstilsynet, associated with safety standards and supervision, and Flyvesikringstjenesten, associated with air traffic services and supporting navigation systems.
Statens Luftfartsvæsen also issued aviation provisions known as BL, short for Bestemmelser for Civil Luftfart. Subjects included aircraft, maintenance workshops, aerodromes, operations and training. These topics show how broadly aviation administration reaches beyond the passenger cabin.
An aircraft, the organisation maintaining it and the people operating it raise different oversight questions. Historical references to SLV therefore need to be read in context: a training provision and an airport provision concern different activities even when the issuing body’s name is identical.

Why Did Statens Luftfartsvæsen Merge in 2010?
A Ministry of Transport press release preserved by the Danish Parliament announced the merger on 27 October 2010. The 2010 merger announcement states that it took effect on 1 November, with the combined authority using the name Trafikstyrelsen.
The stated aim was to bring authority and supervisory work across road, rail and aviation together. The announcement also highlighted stronger international work, including cooperation connected with the European Union.
For readers researching Statens Luftfartsvæsen, the key point is continuity through reorganisation. The disappearance of the old organisational name does not mean Denmark stopped supervising civil aviation. It means the institutional structure changed.
When describing this event, distinguish the announcement date from the effective date. Both October and November 2010 can appear in search results, but they refer to different stages of the same merger.
Where Should You Look for Aviation Information Today?
The current English-language website identifies the organisation as the Danish Civil Aviation and Railway Authority. Its civil aviation services section provides routes into topics such as flight operations, airworthiness, education and certification, aeromedical matters and passenger rights.
Choose the section that matches the question. Someone investigating a professional certificate needs different information from a passenger looking for the appropriate complaint guidance. Searching only the former name Statens Luftfartsvæsen can leave both readers looking at historical material.
Start with the service topic, then check the relevant page’s instructions and update information. This is more useful than copying an email address or procedure from an old SLV document without checking whether it remains current.

Reading an Old Statens Luftfartsvæsen Document
An archived document can answer what the authority published at a particular time. It cannot automatically establish the requirements applying to a present-day situation. Separate the document’s historical value from the question you are trying to answer now.
First, record the title, reference number, date and edition. Second, identify its subject: aircraft maintenance, training, airport operations or another area. Third, look for the corresponding topic in the current official resources.
For example, an old training document may explain the terminology used in a historical course. If your goal is a new qualification, follow the current certification guidance instead of assuming the older application route still applies. The same document can be useful for one purpose and insufficient for another.
Do not assume that an old logo makes a document invalid, either. What matters for current use is its status, amendments and applicability. The Statens Luftfartsvæsen name is a clue about provenance, not a complete answer about validity.
Understanding BL and Current Aviation Rules
The authority’s current aviation rules and regulations page explains the relationship between Denmark’s Air Navigation Act and more detailed provisions. It also describes the BL collection and the international framework influencing aviation regulation.
For a reader encountering BL in a Statens Luftfartsvæsen reference, the abbreviation is therefore a useful search term. Pair it with the specific number or subject rather than relying on a broad search for the former authority alone.
This article is a historical introduction, not a determination of which rule applies to a flight, licence or aircraft. Operational questions need the applicable current official material and, where necessary, clarification from the responsible authority.
