Contents
Quick answer
Yes — register as operator with your NAA, obtain A1/A3.
Weight, C class and EASA subcategory
Maximum take-off mass (MTOM): 45 g. Class identification label: C0.
Even under 250 g, a camera triggers operator registration — same rule as DJI Mini series (EASA FAQ).
Operator registration
Under EASA rules you register as operator with your National Aviation Authority (NAA) — one number displayed on all UAS you own.
1. Register once as a drone operator with your NAA (EU Regulation 2019/947, Article 14).
2. Affix your operator registration number on every UAS you own — readable without tools.
3. Upload the number into the aircraft Remote ID system when the UAS bears a C1–C4 class mark (from 1 Jan 2024).
4. Registration is operator-level: one account covers all drones in Open and Specific categories.
Fees and renewal periods differ slightly by EU member state; see your NAA portal.
Certificate and exams
A1/A3 is the baseline certificate for most recreational Open category operations in EASA member states.
A1/A3 remote pilot certificate: typically 40 questions, 40 minutes, 75% pass mark via your NAA online portal.
- A1/A3 — hobby flights
- A2 — when flying closer to people
- Eligibility test — where to start
Open category rules
Open category: VLOS, max 120 m above ground, respect national geo-zones and UAS geographical zones.
Subcategories A1, A2, A3 depend on aircraft mass, C class label and how close you fly to people.
Legacy aircraft (no C mark, placed on market before 1 July 2022) usually fly under A3 restrictions.
Geo-zones and flight planning
Check your national UTM/geo-zone map before every flight — not only the manufacturer's app.
Manufacturer app geo-awareness is helpful but not a legal substitute for your national UTM map.
