Operational Manual for Drone Operators: Practical Construction and Regulatory Compliance

Begin with Actual Operations

Drafting an operational manual begins with a thorough analysis of actual drone operations. This means that as a UAS operator, you first clearly define which drone configurations, operations, and environments are relevant before choosing which regulatory route (Open, Specific, STS, PDRA, or SORA) applies.

By defining this operational context early, you prevent the manual from becoming a collection of loose standard texts that do not align well with the practicalities of your organization.

• **Operator and Registration Details**: Identity and contact information of the UAS operator and any specific registration and identification measures.
• **Roles, Authorities, and Substitution**: Who performs which tasks, including authorized persons for flight execution, maintenance, and emergency procedures, and who can replace them.
• **UAS Configurations and Maintenance**: Specifications of used drones, sensors, software and hardware versions, with procedures for maintenance and inspection.
• **Operational Environment, Airspace, and Ground Risks**: Description of the operational volume, airspace segment, location, and risks to people and property on the ground.

Develop Procedures Clearly and Systematically

For each operational process, describe the preparation, decision criteria, responsible roles, and necessary registrations. Clearly distinguish between normal flight procedures, contingency procedures for deviations, and emergency procedures for emergencies.

Use regulatory-compliant references to checklists and registers. This prevents repetition and ensures that the manual remains manageable and suitable as evidence during an assessment or supervision.

• **Normal Procedures**: Standard actions for safe execution, such as pre-flight checks, communication, and flight monitoring.
• **Contingency Procedures**: Actions for unexpected problems that are not acute emergencies, such as GPS failure or communication loss.
• **Emergency Procedures**: Specific actions in accidents or unsafe situations, including Emergency Response Plan (ERP) and communication to involved authorities.

Carefully Manage Versions and Evidence

An operational manual is a living document subject to changes. Manage it via a revision log so that it is clear which changes were made when and by whom.

With each revision, ensure an up-to-date table of contents, appoint a document owner responsible for maintenance, and make fixed references to appendices. After a change, always check whether procedures, ERP, training, and maintenance records are still up-to-date.

• **Revision Log**: Document each change, the date, and responsible person.
• **Table of Contents**: Keep it clear and accessible.
• **Document Owner**: Monitors currency, coordinates updates, and communicates with the team.

Compliance with European and National Regulations

The operational manual must comply with European UAS regulations (EASA Easy Access Rules for UAS), which provide details on classification of categories (Open, Specific), operational authorizations, risk assessments (such as SORA), and standards for operators.

Additionally, the Irish competent authority, the Irish Aviation Authority (IAA), may have national guidelines and procedures, for example, for state or more complex operations, in which the manual plays a central role. This documentation may sometimes contain additional requirements for the manual and related documents such as the ConOps and ERP.

A thorough compliance requires integrating both levels into the manual so that it meets all relevant requirements and can be used in permit applications, exemptions, and audits.

• **EASA Easy Access Rules for Unmanned Aircraft Systems**: Basic regulations for UAS operations in the EU.
• **IAA RPAS Operations Manual Guidelines**: National specifications and regulations for Ireland.
