A guide to BVLOS Operations

When businesses start using drones, it’s important to understand not just what the technology can do, but what the regulations allow.

What is BVLOS?

BVLOS operations occur when the drone is no longer visible to the pilot or visual observer during flight.

Most aviation authorities (including CASA in Australia and the FAA in the U.S.) require drones to remain within visual line of sight (VLOS) under standard rules. That’s because visual oversight helps ensure:

• The drone’s position and direction are known at all times
• Other aircraft and hazards can be avoided
• People and property on the ground remain protected

BVLOS operations rely on technology and systems that provide the same situational awareness, without direct eyesight.

Why BVLOS Matters

BVLOS opens the door to far more advanced drone use cases, including:

• Accessing remote or hazardous environments
• Covering much larger operational areas
• Increasing inspection frequency and efficiency
• Reducing costs compared to traditional methods
• Supporting automated drone-in-a-box deployments

As regulations evolve, BVLOS is expected to become a key foundation for scalable commercial drone operations.

Technology Needed for Safe BVLOS Flight

Because the pilot cannot directly see the aircraft, BVLOS requires highly reliable systems, including:

Control and Command Links

A strong communication connection is essential, often supported by internet connectivity and redundant transmission systems.

Live Telemetry and Video

Pilots need continuous access to:

• Live video feed
• Telemetry data
• Drone location, heading, and altitude

Sense and Avoid Capability

BVLOS flights must account for other airspace users. Systems such as ADS-B alerts and detect-and-avoid technology help reduce collision risk.

Failsafes

Reliable contingency measures are critical, including smart Return-to-Home (RTH) functions if signal is lost.

Regulatory Compliance in Australia

In Australia, BVLOS approval is managed through CASA and requires detailed planning and authorisation.

Operators typically submit:

• CASA BVLOS application forms (e.g. 101-09)
• Comprehensive risk assessments
• Communication and contingency plans
• Maps and airspace documentation
• Evidence of training and operational competence

CASA defines multiple BVLOS scenarios depending on factors like:

• Population density
• Terrain and vertical obstacles
• Remote area operations
• Emergency service use cases

Approval is possible, but the process is rigorous to ensure safety.

Key BVLOS Considerations Before Flight

BVLOS operations require more than just the right drone. Organisations need to address:

• Regulatory approvals and operational authorisations
• Skilled pilots with BVLOS-specific training
• Risk assessment for each mission
• Insurance coverage and liability planning
• Robust command-and-control infrastructure
• Airspace awareness and safety systems

BVLOS is a capability built on planning, systems, and compliance, not just flight distance.

The Future of BVLOS Operations

As drone technology matures and regulations continue evolving, BVLOS will enable new levels of drone integration across industries.

Potential growth areas include:

• Large-scale infrastructure inspection
• Scientific and environmental monitoring
• Search and rescue and emergency response
• Automated long-term drone deployments

The path forward will require:

• Continued training and certification standards
• Sophisticated UAV systems
• Clear operational frameworks from regulators
• Responsible and well-documented use by industry
