1.3 Remote Pilot vs. UAS Operator Responsibilities & Proof of Completion
Key Takeaways
- A UAS Operator is the legal entity or natural person managing the drone and its operational setup, whereas the Remote Pilot is the individual physically manipulating the flight controls or monitoring autonomous trajectory.
- The UAS Operator is legally mandated to register with the national aviation authority, maintain the fleet, ensure mandatory third-party liability insurance, and establish operational procedures.
- The Remote Pilot is solely responsible for tactical in-flight safety, conducting pre-flight checks, assessing weather and airspace restrictions, maintaining VLOS, and yielding right-of-way to all manned aircraft.
- The Open Category A1/A3 qualification ('Proof of completion of online training') requires passing a 40-question multiple-choice exam with at least 75% (30 correct answers), remaining valid for 5 years across Europe.
- The baseline European minimum age for a Remote Pilot in the Open Category is 16 years, though Member States may lower this to 12 or 14 years under national law, or waive it entirely for toy drones or drones under 250 g flown under adult supervision.
1.3 Remote Pilot vs. UAS Operator Responsibilities & Proof of Completion
[!NOTE] Two Distinct Legal Personalities: One of the most frequently tested concepts on the EASA A1/A3 examination is the clear legal separation between the UAS Operator and the Remote Pilot. Even when an individual hobbyist flies their own drone—acting as both operator and pilot simultaneously—the law views them as wearing two different legal "hats," each bearing distinct statutory obligations.
In European aviation law, responsibilities are apportioned strategically between the entity responsible for the aircraft and organization (the Operator) and the individual responsible for manipulating the controls during flight (the Remote Pilot).
UAS Operator vs. Remote Pilot: Legal Definitions
The UAS Operator (Natural or Legal Person)
Defined in Article 2(2) of Regulation (EU) 2019/947:
'unmanned aircraft system operator' ('UAS operator') means any legal or natural person operating or intending to operate one or more UAS.
The operator is the administrative, legal, and organizational owner or lessee of the drone system. This can be:
- A private individual hobbyist who purchased a drone.
- A self-employed freelance photographer.
- A commercial corporation, utility company, or television production studio.
The Remote Pilot (Natural Person Only)
Regulation (EU) 2019/947 does not define this term itself. The definition sits in Article 3(27) of Delegated Regulation (EU) 2019/945, mirroring Article 3 of Regulation (EU) 2018/1139:
'Remote pilot' means a natural person responsible for safely conducting the flight of an unmanned aircraft by operating its flight controls, either manually or, when the unmanned aircraft flies automatically, by monitoring its course and remaining able to intervene and alter the course at any time.
The remote pilot is always a human being. A corporation can be a UAS Operator, but a corporation can never be a Remote Pilot.
Statutory Duties of the UAS Operator (UAS.OPEN.050 & Article 14)
The UAS Operator carries institutional, administrative, and airworthiness responsibilities:
- Digital Registration: Must register with the National Aviation Authority of the Member State where they reside or have their registered office (under Article 14). The operator receives a unique UAS Operator Registration Number (e.g.,
DEU123456789abc-xyz, where-xyzis a secret confirmation code). - Displaying the Operator ID: Must affix the Operator Registration Number (excluding the secret confirmation digits) to every drone in their fleet. If the drone features a Direct Remote Identification (DRI) system, the operator must upload the registration number into the drone's broadcast firmware.
- Fleet Airworthiness & Maintenance: Must ensure that all unmanned aircraft are maintained in a safe, airworthy operating condition according to the manufacturer's user manual and maintenance instructions.
- Mandatory Third-Party Insurance: Must ensure that appropriate third-party liability insurance is active for all flights, in accordance with Regulation (EC) No 785/2004 or applicable national insurance legislation.
- Pilot Competency Oversight: Must ensure that any remote pilot assigned to operate a company drone holds the required competency certificate (A1/A3, A2, or STS) and is fully familiar with the aircraft's operating handbook.
- Operational Procedures: In commercial contexts, the operator must develop and maintain standard operating checklists, emergency procedures, and risk mitigation protocols.
Statutory Duties of the Remote Pilot (UAS.OPEN.060)
The Remote Pilot is directly and personally responsible for the tactical safety of the flight before takeoff, during airborne maneuvers, and upon landing:
Pre-Flight Verification Duties
Before initiating any flight, the remote pilot must personally verify:
- Registration Display: The drone visibly displays the valid UAS Operator Registration Number.
- Airspace & Weather Assessment: Official UAS geographical zones (Article 15 maps) have been checked for no-fly restrictions or NOTAMs, and current meteorological conditions (wind speed, gusts, cloud cover, visibility, rain, temperature) are within the aircraft's operating envelope.
- Airframe Inspection: Propellers are free of cracks, chips, and warping; motor mounts are secure; sensors and cameras are clean; the battery is securely latched with sufficient charge for the intended flight plus emergency reserve.
- Failsafe Settings: Fail-safe behaviors—particularly the Return-to-Home (RTH) altitude—are correctly configured to clear all surrounding buildings, trees, and terrain obstacles in the event of a lost command-and-control link.
In-Flight Conduct & Human Performance Duties
During the flight, the remote pilot must:
- Maintain Direct VLOS: Keep continuous, direct, unaided visual contact with the unmanned aircraft to monitor its flight path and airspace surroundings.
- Right-of-Way Rule (Absolute Priority for Manned Aviation): Give way immediately, unconditionally, and without hesitation to all manned aircraft (commercial airliners, general aviation planes, medical helicopters, gliders, hot air balloons). If a manned aircraft is spotted or heard, the remote pilot must immediately descend, steer clear, or land.
- Maintain Distance Buffers: Respect subcategory proximity rules (never flying over crowds in A1; keeping 30 m / 5 m from people in A2; keeping 150 m from populated areas in A3).
- Fitness to Fly: Never execute a flight if their physical or mental faculties are impaired due to fatigue, illness, stress, medication, alcohol, or psychoactive drugs. European aviation enforces a zero-tolerance policy for flying while impaired.
- Terminate Flight if Risk Increases: Land or abort the flight immediately if weather deteriorates, uninvolved people enter the exclusion zone, or an emergency aircraft approaches.

The European Pilot Competency Architecture
Regulation (EU) 2019/947 defines a progressive, tiered qualification structure for remote pilots in the Open Category:
QUALIFICATION TIERS IN THE OPEN CATEGORY
│
┌─────────────────────────────┴─────────────────────────────┐
▼ ▼
+---------------------------------------+ +---------------------------------------+
| OPEN CATEGORY A1/A3 PROOF | | OPEN CATEGORY A2 CERTIFICATE |
| "Proof of Completion of Training" | | "Remote Pilot Cert. of Competency"|
+---------------------------------------+ +---------------------------------------+
| - Mandatory foundation for all pilots | | - Advanced proximity flying (C2 class)|
| - Online training + 40-question exam | | - Prerequisite: Hold A1/A3 certificate|
| - Passing score: 75% (30/40 correct) | | - Self-practical training declaration |
| - Validity: 5 years (all EU + EFTA) | | - 30-question theoretical proctored exam|
| - Permits C0, C1 (A1) & C3, C4 (A3) | | - Permits 30 m / 5 m buffer from people|
+---------------------------------------+ +---------------------------------------+
1. The A1/A3 "Proof of Completion of Online Training"
The baseline certification for all civil drone pilots flying in Europe. It is completed via the digital portal of any Member State's NAA.
- Syllabus (9 Mandatory Subjects): Aviation safety, airspace restrictions and geographical zones, aviation regulation, human performance limitations, operational procedures, UAS general knowledge, privacy and personal data protection, insurance, and security.
- Examination Logistics: A 40-question multiple-choice examination delivered online. To ensure fairness, questions are drawn randomly from an official question bank covering all 9 subjects.
- Passing Standard: Exactly 75% (a minimum of 30 out of 40 questions answered correctly).
- Validity: 5 years. Upon expiration, remote pilots renew their competency through refresher training or re-examination in accordance with NAA procedures.
- Privileges: Authorizes the remote pilot to fly C0 and C1 drones in Subcategory A1, and C3, C4, and legacy unclassed drones up to 25 kg in Subcategory A3.
2. The A2 "Remote Pilot Certificate of Competency" (A2 CofC)
For pilots wishing to operate heavier C2-class drones (up to 4 kg) in urban and populated settings close to uninvolved people:
- Prerequisites: Must hold a valid A1/A3 Proof of Completion + complete a self-declared practical flight training program in an A3 environment.
- Examination: An additional 30-question multiple-choice theoretical exam administered under supervision by the NAA or a recognized entity, focusing on meteorology, UAS flight performance, and technical/operational mitigations for ground risk.
- Privileges: Allows flying C2-class drones down to a horizontal distance of 30 metres from uninvolved persons, or 5 metres if operating in low-speed mode.
3. Specific Category STS Theoretical Knowledge
Pilots operating under European Standard Scenarios (STS-01 or STS-02) must complete an additional 40-question theoretical examination covering operational risk mitigations and pass a formal practical skills assessment conducted by an accredited training entity.
Minimum Age Requirements & National Derogations
To ensure cognitive and emotional maturity in managing aviation risk, Article 9 of Regulation (EU) 2019/947 establishes age thresholds:
+-----------------------------------------------------------------------------------+
| MINIMUM AGE FOR REMOTE PILOTS (ARTICLE 9) |
+-----------------------------------------------------------------------------------+
| Standard European Baseline: 16 YEARS OF AGE |
| |
| National Derogation Rights: Member States may lower the minimum age by up to: |
| - 4 years in the Open Category (down to 12 years) |
| - 2 years in the Specific Category (down to 14 yrs)|
| |
| Zero Minimum Age Exceptions: - Drones classified as TOYS (Directive 2009/48/EC) |
| - Privately built drones with MTOM < 250 g |
| - Flying under the DIRECT SUPERVISION of a |
| certified pilot aged 16 or older |
+-----------------------------------------------------------------------------------+
National Derogations in Practice
Because Article 9 permits Member States to adjust minimum age limits within their own sovereign territory, national variations exist:
- Germany, Austria, Sweden: Lowered the Open category minimum age to 14 years.
- France, Ireland, Spain: Maintained the baseline European standard of 16 years.
The Direct Supervision Rule
A minor who does not meet the minimum age requirement may still legally pilot a drone if they are under the direct personal supervision of a remote pilot who:
- Meets the minimum age of at least 16 years, and
- Holds the appropriate competency certificate (e.g., A1/A3 Proof of Completion) for the drone and subcategory being flown.
Practical Flight Scenario: Corporate Deployment & Liability
+-----------------------------------------------------------------------------------+
| SCENARIO: Apex Surveying Ltd. employs Jonas, a 22-year-old surveyor, to map a |
| construction site using a company-owned C3-class drone (MTOM 12 kg). |
| |
| 1. The Operator: Apex Surveying Ltd. is the UAS Operator. The company registers |
| with the NAA, affixes its Operator ID to the drone, purchases a commercial |
| aviation liability insurance policy, and ensures maintenance logs are kept. |
| 2. The Remote Pilot: Jonas is the Remote Pilot. He must hold a valid A1/A3 |
| certificate, conduct pre-flight safety inspections, check local geo-zones, |
| maintain VLOS, and maintain a 150-metre buffer from nearby residential areas. |
| 3. Legal Liability during an Incident: If the drone crashes into a parked car |
| due to Jonas flying while severely sleep-deprived and distracted, Jonas is |
| personally liable for violating pilot fitness and operational rules, while |
| Apex Surveying's mandatory insurance covers the third-party property damage. |
+-----------------------------------------------------------------------------------+
Common Exam Traps & Pitfalls
- Trap: Conflating the Operator ID and Pilot Certificate Number: The Operator Registration Number (e.g.,
DEU123456789abc) must be displayed on the drone. The Remote Pilot Certificate number (e.g.,DEU-RP-987654321) belongs to the individual human and is never affixed to the drone airframe. - Trap: Believing the A1/A3 Certificate Requires a Practical Flight Test: Obtaining the A1/A3 Proof of Completion requires only online theoretical study and a 40-question online exam. There is no practical flight test with an examiner.
- Trap: Unsupervised Minors Flying Under-250g Drones with Cameras: While toy drones have no minimum age, a non-toy camera drone weighing 240 g (such as a consumer photography drone) requires the pilot to meet the national minimum age (16, or 14/12 where derogated) unless directly supervised by a certified adult.
- Trap: Thinking Alcohol Limits Do Not Apply to Hobby Drone Pilots: Under UAS.OPEN.060, fitness-to-fly regulations apply universally to all remote pilots. Flying while impaired by alcohol or drugs is a serious aviation offense regardless of drone size or non-commercial intent.
