NOTE: This is a blog tailored for RPAS operators, specifically designed to bridge the gap between high-level ISO standards and the practical reality of Canadian aviation regulations (Transport Canada).

As the Canadian drone industry matures, the bar for professionalism is rising. With Transport Canada’s new RPAS Operator Certificate (RPOC) framework for complex operations (like BVLOS) rolling out, operators are looking for robust ways to demonstrate safety and competence.

Enter ISO 23665 and ISO 21384-3—the international gold standards for UAV training and operations.

While not explicitly mandatory in the Canadian Aviation Regulations (CARs) yet, adopting these standards is one of the most powerful moves an organization can make to fast-track RPOC approvals, win enterprise contracts, and ensure safety. This guide explains what they are and how to bake them into your organization’s DNA.

What are these ISO Standards?

The International Organization for Standardization (ISO) has released a suite of documents specifically for Unmanned Aircraft Systems (UAS). Think of these not as laws, but as globally recognized "best practices" that prove your organization operates at a professional aviation level.

There are two key standards you need to know:

ISO 23665 – Training for Personnel Involved in UAS Operations: This standard sets the benchmark for how you train your pilots and crew. It moves beyond simple "stick skills" and focuses on competency-based training, requiring defined learning objectives for specific operational risks.
ISO 21384-3 – Operational Procedures: This complements the training standard by defining how you fly. It covers safety management, flight planning, and risk assessment methodologies.

The "Meat" of the Standards: What’s Inside?

ISO 23665 (The Training Standard)

This standard dictates that training must be structured around competency. It requires:

Curriculum Design: Training must be tailored to the specific environment (e.g., urban, maritime, BVLOS) rather than a generic "one size fits all" course.
Instructor Qualifications: It sets criteria for who is allowed to teach (both flight and ground school).
Student Assessment: It mandates rigorous testing of knowledge, skills, and attitude (KSA) before a pilot is released for operations.

ISO 21384-3 (The Ops Standard)

This standard aligns closely with traditional aviation safety management systems (SMS). It requires:

Operational Risk Assessment (ORA): A formal method for identifying hazards before every flight.
Data Protection: Protocols for handling data captured by the drone (privacy and security).
Maintenance Logs: Strict requirements for documenting aircraft airworthiness.

How to Employ These Standards into Your RPAS Organization & Manuals

If you are applying for an RPAS Operator Certificate (RPOC) in Canada, you are required to affirm you have an Operations Manual and a Training Program. Transport Canada leaves the specifics open-ended, asking you to "reflect your operational reality." Be prepared if they ask for a copy of your manuals"

Here is how you use ISO to build a bulletproof application:

1. In Your "Training Program" Manual

Instead of vaguely stating "pilots will be trained," reference ISO 23665 competencies.

Drafting the Manual: Create a "Competency Matrix" in your manual. List specific skills (e.g., "Loss of Link Procedures in BVLOS") and reference the ISO requirement for recurrence training (re-testing pilots every 12–24 months).
Execution: Adopt a "Task-Based" training log. Don't just log flight hours; log specific maneuvers performed to ISO standards (e.g., "Precision hover in manual mode within 0.5m deviation").

2. In Your "Standard Operating Procedures" (SOPs)

Use ISO 21384-3 to structure your flight workflows.

Drafting the Manual: Your "Pre-Flight Planning" section should mirror the ISO’s risk assessment requirements. Include a "Go/No-Go" decision matrix based on specific ISO safety margins (e.g., weather buffers, battery reserve minimums).
Execution: Create checklists that are ISO-compliant. For example, your Emergency Response Plan (ERP) should strictly follow the ISO hierarchy of "Aviate, Navigate, Communicate."

3. In Your "Safety Management System" (SMS)

Drafting the Manual: If you are appointing an Accountable Executive (a requirement for RPOC), use the ISO definition of management responsibility to define their role. This shows Transport Canada that your executive isn't just a figurehead but has active oversight duties.

Who Uses This Standard?

Enterprise Clients: Large companies in Oil & Gas, Mining, and Utilities (e.g., Suncor, Hydro-Québec) often require vendors to meet ISO standards to bid on contracts, as their internal safety auditors recognize ISO over basic regulatory compliance.
RPOC Applicants: Operators applying for "Level 1 Complex Operations" (Low-Risk BVLOS) use these standards to prove to regulators that their internal systems are robust enough to handle the risk.
Flight Schools: Top-tier drone schools align their curriculum with ISO 23665 to offer "industrial grade" certification that goes beyond the basic Transport Canada Advanced Exam.

Do Transport Canada or NAV CANADA Use These Standards?

Transport Canada (TC): Currently, TC does not explicitly mandate ISO 23665 or 21384-3 in Part IX of the Canadian Aviation Regulations. However, they are deeply involved in the ISO working groups (ISO/TC 20/SC 16).

Why it matters: When you apply for a Special Flight Operations Certificate (SFOC) or an RPOC, you must demonstrate "mitigation of risk." Citing that your manuals and training are built on ISO standards is a powerful way to satisfy TC inspectors that your operation is safe.

NAV CANADA: NAV CANADA manages airspace and currently focuses on the NAV Drone app and RNP (Required Navigation Performance) standards rather than pilot training ISOs. However, as they move toward RPAS Traffic Management (RTM), operators complying with ISO operational standards (like electronic conspicuity and formalized comms procedures) will find it much easier to integrate into controlled airspace workflows.

Conclusion

Adopting ISO standards is voluntary, but in the new era of the RPAS Operator Certificate, it is the differentiator between a hobbyist and a professional aviation organization. By embedding ISO 23665 and 21384-3 into your manuals today, you are future-proofing your business for the complex operations of tomorrow.
