One-to-Many operations refer to a scenario where a single Remote Pilot or Ground Control Station (GCS) manages multiple RPAS (Remotely Piloted Aircraft Systems)—either simultaneously or in sequence. This operational model is especially useful for large-scale inspections, monitoring, or surveillance tasks where multiple drones are needed to cover wide areas efficiently.

While One-to-Many operations offer increased productivity and cost savings, they also introduce higher complexity and regulatory scrutiny. They require robust automation, failsafes, operational procedures, and clear command-and-control structures to meet CASA or CAA requirements.

Hover UAV provides expert support to help organisations plan, apply for, and safely execute One-to-Many operations. Our services include:

• Regulatory pathway planning: We help you determine the best approach for One-to-Many operations under CASA or CAA frameworks.

• Risk assessments & SORA: We prepare detailed risk assessments and mitigation strategies aligned with Specific Operations Risk Assessment (SORA) methodology.

• CONOPS development: We craft a clear, regulator-ready Concept of Operations that outlines your proposed One-to-Many workflows and safety procedures.

• System and procedure validation: We evaluate your hardware, software, automation, and human factors to ensure safe, compliant execution.

• Training & documentation: We provide tailored training for your team and update your operations manual to reflect One-to-Many capabilities.

Whether you’re using drone-in-a-box systems, fixed-wing platforms, or large multirotor fleets, Hover UAV ensures your One-to-Many operation is safe, scalable, and regulator-ready.

BVLOS SAIL III and IV refer to medium-risk Beyond Visual Line of Sight (BVLOS) drone operations, as classified under the Specific Operations Risk Assessment (SORA) framework. SAIL, or Specific Assurance and Integrity Level, ranges from I (low risk) to VI (high risk). Operations classified as SAIL III or IV typically involve increased complexity, higher potential risk to people or other airspace users, and therefore require more stringent safety mitigations and regulator engagement.

What Makes SAIL III/IV Operations Different?

Operations at SAIL III or IV may involve:

• Flights over or near populated areas

• Shared airspace with crewed aviation

• More advanced or long-range platforms

• Multiple aircraft or complex mission profiles

• Limited visual line-of-sight contingency options

Because of these factors, SAIL III/IV operations require more detailed safety assurance, including:

• Enhanced technical mitigations (e.g. detect-and-avoid systems)

• Operational Safety Objectives (OSOs) with higher robustness levels

• Detailed CONOPS, risk assessments, and emergency procedures

• Validation through flight testing, procedural audits, and engagement with airspace stakeholders like ATC or other airspace users

At Hover UAV, we specialise in supporting complex BVLOS operations and are currently working on such approvals. Our services include:

SORA development: Full preparation of risk assessments, OSO matrices, and SAIL classification

CONOPS writing: Regulator-ready Concept of Operations aligned with your use case

System design reviews: Ensure your platform, communications, and redundancies meet the required robustness

Flight test planning: Assist with validation flights, test objectives, and reporting

Stakeholder engagement: Liaise with CASA, CAA, and airspace users where needed

We help you navigate the added complexity of medium-risk BVLOS with clarity, structure, and confidence—reducing approval times and increasing operational readiness.

Yes, drone operations can be conducted in No-Fly Zones, but special authorisation is required. A No-Fly Zone—also known as a Restricted Area, Prohibited Area, or Controlled Airspace—is airspace where drone flights are limited or prohibited due to safety, security, or privacy concerns. These areas often include:

Airports and approach/departure paths

Military bases and defence sites

Prisons, critical infrastructure, and government facilities

Temporary restricted areas (e.g., major events, bushfires)

Operating in these zones without prior approval is illegal and may result in enforcement action.

Hover UAV specialises in obtaining the necessary permissions and designing safe operations in restricted or complex airspace. We can:

• Assess the airspace classification and determine whether the area is controlled, restricted, or prohibited

• Prepare and submit authorisation requests to CASA or CAA, including RAAF coordination if needed

• Engage with Airservices Australia or relevant ATC units to secure approvals and flight authorisations

• Develop robust risk assessments and CONOPS tailored to high-risk or sensitive areas

• Implement mitigations, such as geofencing, fail-safe programming, airspace observers, and comms protocols

• Coordinate with on-site authorities (e.g. airport operators, emergency services, venue security)

Whether you’re flying near an airport, over a secure facility, or conducting emergency response operations, Hover UAV ensures your mission is safe, compliant, and regulator-approved.

Developing clear, compliant, and effective operational procedures is essential for safe and scalable drone operations, especially under ReOC (Australia) or Part 102 (New Zealand) approvals. Well-documented procedures help ensure your team operates consistently, meets regulatory requirements, and is prepared for audits, incidents, or complex missions.

At Hover UAV, we provide end-to-end support in developing, reviewing, and optimising operational procedures tailored to your unique use case. Our services include:

Custom Procedure Development: We create detailed, regulator-ready procedures covering all aspects of RPAS operations—from pre-flight planning, emergency responses, and maintenance, to mission-specific workflows like BVLOS, EVLOS, or OONP.

Compliance Alignment: Procedures are written to align with CASA or CAA regulations, your ReOC/Part 102 conditions, and best-practice safety standards (including BARS).

Operational Integration: We ensure procedures are practical, clear, and easily integrated into your day-to-day workflows, flight planning tools, and Safety Management System (SMS).

Documentation Updates: We revise and modernise existing procedures to reflect changes in technology, risk profiles, or regulatory conditions.

Training and Implementation Support: Once developed, we help you train your team and embed these procedures across your organisation—ensuring understanding, adoption, and readiness for audits or inspections.

Whether you’re just getting started or evolving a mature drone program, Hover UAV ensures your procedures are fit-for-purpose, regulator-approved, and operationally effective.

Large UAS approvals refer to regulatory authorisations required to operate Uncrewed Aircraft Systems (UAS) over 25 kg. These heavier platforms—used in sectors like defence, logistics, mining, and long-range surveillance—fall outside standard commercial drone regulations and require a more rigorous approval process through CASA (Australia) or CAA (New Zealand).

Operating large UAS often involves complex airspace integration, enhanced safety cases, and technical justifications for everything from airworthiness to command and control systems. These operations typically exceed the scope of standard ReOC or Part 102 approvals.

With proven success delivering complex approvals, Hover UAV ensures your large UAS operations are compliant, scalable, and regulator-ready—whether you’re deploying for commercial, government, or special-purpose missions.
