EASA STS preparation
How to qualify for European STS operations
Understand the separate STS theory certificate, scenario-specific practical accreditation and operator requirements before choosing training.
By Airspace School · Information checked
Theory and practical competence are separate
The pilot needs a certificate of remote pilot theoretical knowledge for standard scenarios and accreditation of completion of practical skill training for the scenario being flown. STS-01 and STS-02 share a theory framework, but practical training and assessment must cover the relevant scenario. Completing a theory preparation course is not the practical accreditation.
Complete the theory route
The route includes the A1/A3 online training and examination, followed by an additional STS examination with the authority or a body it designates. The standard paper has at least 40 questions. Holders of an A2 certificate have a reduced examination requirement of at least 30 questions across five subjects; confirm how the examining body administers that route.
Check the operation as well as the pilot
The operator must meet all requirements of the chosen scenario, including the appropriate C5 or C6 aircraft, controlled ground area and operational declaration. Wait for the authority’s confirmation of receipt and completeness before operating under the declaration. A theory certificate alone is not an operational authorisation.
