Aircraft Detection Lighting Systems (ADLS) combine aircraft detection technology with aviation obstruction lighting to control when warning lights operate around applicable structures and projects.
These sensor-based systems detect approaching aircraft and activate the associated obstruction lights according to the required operating conditions. ADLS is particularly associated with wind-energy projects, where aircraft-triggered operation can reduce unnecessary nighttime obstruction lighting while maintaining the required lighting response when aircraft approach.
Aviation warning lights are also used on communication towers, broadcast towers, buildings, cranes, industrial structures, and other elevated installations. Depending on the application, modern systems can incorporate LED obstruction lights, controllers, monitoring, communications, and automated operating functions.
The appropriate system depends on the structure, location, applicable aviation requirements, required obstruction-lighting configuration, controls, monitoring, electrical requirements, and project specifications.
Aircraft Detection Lighting Systems can integrate aircraft detection with aviation obstruction lighting for wind turbines and other applicable elevated-structure projects.

What Are Aircraft Detection Lighting Systems?
Aircraft Detection Lighting Systems, commonly abbreviated ADLS, are sensor-based systems that detect aircraft approaching an obstruction or group of obstructions and control the associated aviation obstruction lighting.
Rather than operating specified obstruction lights continuously throughout applicable nighttime periods, an ADLS can activate the lighting when approaching aircraft are detected and maintain the required lighting response while the aircraft remains within the applicable coverage area.
An ADLS can incorporate:
-
Aircraft-detection sensors
-
Aviation obstruction lights
-
Lighting controllers
-
Monitoring equipment
-
Communications
-
Alarm functions
-
Power and electrical components
-
System-failure response functions
The aircraft warning lights remain an essential part of the system. ADLS changes how the obstruction lighting is controlled; it does not eliminate the need to establish the correct obstruction-light type, placement, operating characteristics, and project configuration.
How Aircraft Detection Lighting Systems Work
An Aircraft Detection Lighting System monitors a defined area around an obstruction or group of obstructions for approaching aircraft.
When the system detects an aircraft meeting the applicable activation criteria, it signals the obstruction-lighting system to turn on. The required warning lights remain illuminated according to the system’s operating requirements while the aircraft is within the applicable coverage area.
After the aircraft clears the defined area and the applicable operating conditions are satisfied, the system can return the obstruction lighting to its standby state.
ADLS should therefore be considered a coordinated system involving aircraft detection, controls, obstruction lighting, monitoring, communications, power, and failure-response functions rather than simply a sensor connected to a warning light.
Aircraft Detection Lighting Systems for Wind Turbines
Wind-energy projects are a major application for Aircraft Detection Lighting Systems.
Wind turbines requiring aviation obstruction lighting commonly use specified flashing obstruction lights positioned according to the applicable aviation requirements and project determination. Within a wind farm, the required lighting arrangement can depend on turbine height, location, spacing, and the overall project configuration.
An ADLS can control the associated wind-turbine obstruction lights so they activate when aircraft approach the project rather than operating continuously throughout applicable nighttime periods.
This approach can reduce unnecessary nighttime light operation and its effects on surrounding communities while maintaining the required aircraft-triggered obstruction-lighting response.
A wind-energy ADLS project should be evaluated as a complete system, including:
-
Aircraft detection
-
Detection coverage
-
Required aviation obstruction lights
-
Lighting controls
-
Monitoring and alarms
-
Communications
-
Electrical power
-
Failure-response functions
-
Applicable aviation approval and project requirements
ADLS Hazard Analysis and Risk Assessment
Aircraft Detection Lighting Systems introduce additional system considerations because aircraft detection, obstruction-light activation, controls, monitoring, communications, and failure-response functions must operate together as intended.
Depending on the project and applicable approval process, an ADLS hazard analysis or risk assessment may consider factors such as:
-
Aircraft detection coverage
-
Terrain and site conditions
-
Loss of aircraft tracking
-
Obstruction-light activation
-
Sensor or detection-system failures
-
Controller failures
-
Communications failures
-
Electrical power interruptions
-
Monitoring and alarm functions
-
Required failure-response conditions
The purpose of this evaluation is broader than selecting an aviation warning light. It considers how the detection and obstruction-lighting systems interact and how applicable failure conditions are addressed.
Formal hazard-analysis and risk-assessment requirements should be determined by the applicable aviation authority, project engineer, ADLS provider, and project approval process.
For lighting procurement, the resulting project requirements can help establish the required obstruction lights, electrical characteristics, controllers, monitoring interfaces, and system-compatibility requirements.
ADLS Detection Coverage and Failure Response
Detection coverage is a critical part of an Aircraft Detection Lighting System because approaching aircraft must be identified with sufficient time for the associated obstruction lighting to respond according to the applicable system requirements.
Site conditions such as terrain can also affect whether the required detection coverage can be achieved.
Failure response is another important consideration. An ADLS should be designed and operated according to the applicable requirements for conditions such as loss of aircraft detection, communications problems, controller faults, or other system failures.
For project planning, detection coverage, obstruction-light operation, controls, monitoring, communications, power, and failure response should therefore be evaluated as parts of the complete system.
Aircraft Warning Lights for Towers
Communication towers, broadcast towers, utility structures, and other elevated tower installations are common aviation obstruction-lighting applications.
Tower systems can incorporate LED obstruction lights, controllers, monitoring equipment, communications, power supplies, and other components according to the required lighting configuration.
The required warning-light type and placement should be determined from the applicable aviation evaluation and project specifications rather than tower height alone.
For detailed FAA tower-lighting requirements and obstruction-light designations, review our FAA Aircraft Warning Light Requirements and Compliance Guide.
Aviation Warning Lights for Tower Cranes
Tower cranes and other elevated construction equipment can create temporary aviation obstructions because their height and configuration alter the profile of a construction site.
Whether a crane requires aviation marking or lighting depends on factors including its height, location, duration, surrounding aviation environment, and applicable aviation determination.
Aircraft warning-light selection for cranes can require consideration of:
- Required light type
- Crane height and configuration
- Mounting location
- Electrical power
- Rotating or moving components
- Temporary installation requirements
- Environmental exposure
- Maintenance access
When an FAA determination or engineering specification is available, use it to establish the required obstruction-lighting configuration before selecting equipment.
Aircraft Warning Lights for Industrial Structures
Industrial facilities can include elevated structures such as smokestacks, process towers, silos, material-handling equipment, rooftop structures, and other installations that may require aviation obstruction marking or lighting.
Requirements depend on factors including structure height, location, surrounding airspace, applicable aviation determination, and project specifications.
Industrial applications may also require consideration of environmental conditions, electrical requirements, mounting, controls, monitoring, and maintenance access.
Aircraft Warning Lights for Buildings
Tall buildings, rooftop antennas, mechanical structures, and other elevated building components may require aviation obstruction marking or lighting depending on their height, location, surrounding airspace, and applicable aviation determination.
Building installations can require consideration of rooftop mounting, electrical supply, controls, monitoring, environmental exposure, maintenance access, and coordination with other rooftop equipment.
The applicable aviation determination and project specifications should establish the required aircraft warning-light configuration.
Aircraft Warning Lights for Utility Structures
Transmission towers, water towers, elevated tanks, and other utility infrastructure may require aviation obstruction marking or lighting depending on their height, location, surrounding airspace, and applicable aviation determination.
Remote utility applications can also require consideration of available power, mounting, controls, monitoring, environmental exposure, and maintenance access.
LED Aviation Warning Lights, Controls and Monitoring
Modern aviation warning-light systems can combine LED obstruction lights with controllers, monitoring equipment, communications, and automated operating functions.
Depending on the product and application, LED technology can reduce power consumption and routine lamp-replacement requirements compared with older source technologies. Monitoring equipment can provide information about fixture or system status and identify specified fault conditions.
Aircraft Detection Lighting Systems add another layer of control by integrating aircraft detection with the operation of the obstruction-lighting system.
