Operational Manual
How to Create an Operational Manual for Drone Flights under PDRA01
An operational manual is essential for conducting drone operations under PDRA01. This predefined risk assessment sets out specific conditions your operation must meet. Within this manual, you document compliance with UK regulations and operational safety measures, providing clear evidence that you, as a UAS operator, satisfy the required criteria.
1. Determine if PDRA01 Applies
The initial step is to verify whether your drone operation fits the PDRA01 scope. PDRA01 is tailored for particular Visual Line of Sight (VLOS) operations with controlled, limited risks. It specifies key requirements such as:
- UAS physical dimensions and maximum take-off mass
- Type of flight being strictly VLOS
- Ensuring the control zone is free from unauthorised public access
- Population density characteristics in the operational area
2. Create a Compliance Matrix to Demonstrate Adherence
A compliance matrix serves as a transparent tool showing which PDRA01 conditions have been met and which remain outstanding. For each PDRA01 criterion, you should record:
- The current status (e.g., fulfilled, ongoing, not applicable)
- References to relevant chapters or documents within your operational manual or supporting evidence such as certificates and registrations
- Any pending actions required to achieve full compliance
3. Develop Operational Procedures That Are Practical and Effective
The core content of your operational manual should be detailed procedures aligning with PDRA01 requirements and tailored to your specific operation and location. Important elements to cover include:
- Defining and marking the controlled ground area precisely
- Methods of VLOS monitoring during the operation
- Communication protocols among crew members to maintain operational safety
4. Provide Evidence That Your Operation Is Safe and Capable
The operational manual forms part of a comprehensive dossier demonstrating that your operation is safe, well-planned and compliant with UK regulations. Essential documents include:
- Crew training records and qualification certificates
- Technical and maintenance reports for your UAS
- Insurance documents meeting UK CAA standards
Frequently asked questions
Can I modify the conditions of PDRA01?
No. PDRA01 conditions are predefined and cannot be altered. If your operation does not fully comply with these conditions, you should pursue an alternative risk assessment process such as a full UK Specific Operating Risk Assessment (UK SORA) or another PDRA pathway.
Is a completed compliance matrix enough to prove compliance?
No. While the compliance matrix helps monitor progress and status, the critical factor is that the underlying procedures are properly developed, implemented in practice, and backed by tangible evidence including certifications and exercised records.
How should I account for UK national regulations alongside PDRA01?
In addition to PDRA01, you must comply with all relevant UK national regulations enforced by the UK Civil Aviation Authority. It is essential to review the current UK regulatory landscape and incorporate these requirements within your operational manual and compliance matrix.
How often should I review and update the operational manual?
The manual should be reviewed regularly—especially after regulatory changes, updates to UAS specifications, procedural modifications or following any incidents. Updates should also reflect changes in training and operational procedures to ensure ongoing compliance and safety.
