Markets
ADLS is approved nationally. We know the path in our markets.
There is no international ADLS standard. What counts is the national aviation authority, its rules and the way it reviews applications.

BNK, AVV MARKING RULES
THE RULES
Demand-controlled night marking is mandatory for wind turbines that require aviation marking. Systems must meet the requirements of the general administrative regulation on obstacle marking.
HOW WE HELP
ADLS projects with all major turbine OEMs. Integration of the detection system with the turbine light control, from planning to acceptance.
NO
Norway
BSL E 2-1 §7a
THE RULES
BSL E 2-1 §7a sets the framework for ADLS. Many wind farm licences include an ADLS condition with a deadline, and Luftfartstilsynet approves each system.
HOW WE HELP
We prepare the technical documentation the operator needs for the pre-assessment and the application to Luftfartstilsynet.
Reference in Norway
Flight-tested against BSL E 2-1 in Norwegian terrain.
In June 2025 we tested a complete Senture ADLS in the Hadeland and Toten region together with a major Norwegian wind farm developer. Aircraft flew different approach corridors and heights, including approaches at the lower detection limit. The system met all detection requirements of BSL E 2-1.
WHEN
June 2025
WHERE
Hadeland and Toten
SENSORS
Primary radar, transponder interrogator (SSR, Mode A/C), passive Mode S and ADS-B reception
SYSTEM
QUAD server and light control unit
RESULT
All detection requirements of BSL E 2-1 met, including approaches at the LDL

South Africa
SACAA AMOC
THE RULES
SACAA approves ADLS through its alternative means of compliance process.
HOW WE HELP
Radar-based ADLS with pilot activated lighting as an additional input. Local delivery with South African civil and installation partners.
AU
Australia
CASA, AC 139.E-05
THE RULES
CASA guidance on obstacle lighting allows ADLS, with performance criteria aligned to FAA AC 70/7460-1M. Where aviation lighting is required, the development approval of the wind farm usually sets the conditions.
HOW WE HELP
ADLS designed to these criteria, including the coverage analysis and technical documentation that CASA and the planning authority ask for.
CL
Chile
DGAC, DAN 14
THE RULES
Obstacle marking is regulated in DAN 14. DGAC accepts radar-based ADLS in principle and requires it case by case in the permit.
HOW WE HELP
Delivery with a local partner for installation, maintenance and warranty service, plus the technical information DGAC requires.
Your market is not listed?
We assess regulatory feasibility for new markets and supply the documentation the authority asks for.
Example designs
Same technology, four very different designs.
Each market sets its own detection requirements, and the terrain decides how many sensors it takes to meet them.
