RPAS Operation Categorisation

RPAS Operation Categorisation

A risk based approach to regulation of unmanned aircraft

The operator should perform a safety risk assessment, identifying mitigation measures, that will be reviewed and approved by the National Aviation Authority.

The safety risk assessment has to address airworthiness, operating procedures and environment, competence of involved personnel and organizations, as well as airspace issues.

5th Certification Workshop     29/01/2015


RPAS Operation Categorisation

√ Proposal 8: to develop adequate equipment and to declare compliance with standards

A risk based approach to regulation of unmanned aircraft

√  Proposal 10: Manufacturers and importers of drones have to comply with the applicable product safety directive

√  Proposal 11: Essential requirements for the intended general product safety directive and related standards …… appropriate for the category and subcategory of the drone


√  Proposal 20: ‘Specific risk operation’…. Each specific aviation risk needs to be analyzed and mitigated through a safety risk assessment

√  Proposal 21: A safety risk assessment shall be performed ….. covering both the drone and the operation, identifying all the risks related to the specific operation, and proposing adequate risk mitigation measures
