Project Background

Located in Western Australia’s Pilbara region, this project serves one of the world’s most active mining and mineral export areas. The airspace regularly accommodates low-altitude aircraft operations, including mining exploration helicopters and general aviation flights.

The project structure is a 135-meter industrial chimney. Due to its height and location, the chimney presents a significant aviation obstruction risk, particularly during:

• Nighttime operations
• Dust storm conditions
• Low-visibility weather

To improve aviation safety compliance and operational reliability, the client decided to upgrade the existing aviation obstruction lighting system with a more dependable long-term solution.

After technical evaluation and environmental assessment, our Type A Medium Intensity Light system was selected for the project.

Why Medium-Intensity Type A Obstruction Lights?

The Pilbara environment creates several engineering challenges:

• Extreme daytime temperatures
• Strong UV exposure
• Seasonal dust storms
• Potential power fluctuations in mining zones

To ensure long-term stable operation, the lighting system was specifically configured for harsh outdoor conditions.

Key Technical Advantages of Medium-Intensity Type A Obstruction Lights

ICAO-Compliant Aviation Warning System

The lighting system complies with ICAO Annex 14 requirements and is certified for international aviation obstruction applications.

Certifications

• ICAO Certified
• CAAC Certified

GPS Synchronized Flashing

One of the core technical features of this aviation obstruction lights project is the GPS synchronization function.

Through satellite signal synchronization, obstruction lights installed at different chimney levels flash simultaneously with millisecond-level accuracy. This significantly improves visual consistency for pilots and avoids disordered flashing effects during nighttime observation.

The GPS synchronization system has already been validated in multiple overseas aviation lighting projects.

Designed for Harsh Environments

Technical Parameter	Specification
Light Source	High-efficiency LED
Daytime Intensity	Up to 20,000 cd
Night Mode	Automatic brightness adjustment
Protection Rating	IP66
Operating Temperature	-40°C to 70°C
Wind Resistance	Up to 240 km/h

The system maintains stable performance under high heat, strong wind, and heavy dust conditions commonly found in mining regions.

Installation Layout

Layered Aviation Warning Design

The aircraft warning lighting arrangement follows the international principle of marking the highest and outermost points of an obstruction structure.

Top Warning Layer

At the top of the 135-meter chimney:

• 3pcs Medium-Intensity Type A Obstruction Lights installed
• 120° evenly distributed layout
• Full horizontal visibility coverage

This configuration ensures the chimney profile remains clearly visible from all flight directions.

Intermediate Warning Layers

Because the chimney height exceeds 45 meters, additional warning layers were added.

Height Position	Lighting Type	Function
90 meters	Medium-Intensity Type B Red Light	Auxiliary warning
45 meters	Medium-Intensity Type B Red Light	Auxiliary warning

The combination of:

• Type A white flashing lights
• Type B red obstruction lights

creates a clearer visual hierarchy while complying with ICAO vertical spacing requirements.

Intelligent Control System

The project also integrates an intelligent control and protection system:

• Automatic day/night switching
• Photoelectric controller operation
• Surge protection device integration
• Reserved solar power interface

This design improves long-term operational reliability in remote mining environments.

Medium-Intensity Type A Obstruction Lights – Project Testing & Commissioning

After installation, the system underwent third-party inspection and commissioning tests.

Test Results

Test Item	Result
Flash Frequency	Approx. 40 flashes/min
GPS Synchronization Accuracy	Microsecond-level
Light Coverage	Meets design requirements
System Stability	Passed continuous operation testing

Performance Under Dust Storm Conditions

During the trial operation phase, the Pilbara region experienced typical dust-heavy weather conditions.

Even under reduced visibility, the aviation obstruction lighting system maintained:

• Strong light penetration
• Stable synchronized flashing
• Clear aviation warning performance

The chimney lights project received positive feedback from on-site operation and maintenance personnel.

Project Value & Application Expansion

This project demonstrates the reliability of Medium-Intensity Type A Obstruction Lights in demanding overseas environments.

Beyond industrial chimneys, the same solution is suitable for:

• High-voltage transmission towers
• Broadcasting towers
• Wind turbines
• Petrochemical structures
• Other tall aviation obstruction structures

Medium-Intensity Type A Obstruction Lights Solution Advantages

✔ ICAO-compliant aviation safety solution
✔ Reliable operation in extreme climates
✔ GPS synchronized flashing technology
✔ Modular installation design
✔ Reduced long-term maintenance costs
✔ Suitable for global aviation obstruction applications

Conclusion

The successful completion of the Pilbara chimney project provides a proven reference for aircraft warning lights installations in mining and industrial environments worldwide.

For similar tall-structure aviation warning projects, ICAO-certified Medium-Intensity Type A Obstruction Lights offer a dependable and standardized solution for long-term operational safety.
