Spain Drone Regulations and ENAIRE ZGUAS Explained

Pilots who have already flown in the US or Japan often bring one habit to Spain that does not transfer cleanly: checking the rulebook of a single agency and assuming that covers everything. Spain splits the question in two. AESA (the Spanish aviation safety agency) is responsible for operator registration, pilot qualifications and operating rules. ENAIRE, the country's air navigation service provider, publishes information on its pages (among others through the ENAIRE Drones platform) on the geographical UAS zones (ZGUAS, Spanish: Zonas Geográficas UAS), which help decide where a given flight may actually take place. A pilot can be fully registered and qualified under AESA's rules and still be flying illegally because they never checked the zones for that exact spot.

Registration depends on weight and camera, not just weight

In Spain, EU Implementing Regulation 2019/947 applies together with Royal Decree 517/2024. Under these rules, operators in the Open category must register if the drone has a maximum takeoff mass of 250 g or more (or can transfer more than 80 joules on impact). Regardless of weight, the duty also applies to any drone with a sensor that can capture personal data, which in practice means almost any camera. The exemption is narrow: toy drones that comply with Directive 2009/48/EC. A 199 g drone with a 4K camera therefore generally needs an operator number too. Anyone who relies on "under 250 g, so no paperwork" regularly overlooks this. You register in only one member state, the one where you live; in Spain the authority for this is AESA. According to the decree, the minimum age for operators is 16.

A1, A2 and A3 are about distance from people, not skill level

Spain's Open category follows the EU structure. The three subcategories differ mainly in how close you may get to uninvolved people.

A1: Permitted are Class C0 drones, Class C1 drones (with active Remote ID and geo-awareness), self-built drones under 250 g, and older drones without a label under 250 g that were placed on the market before 1 January 2024. They may fly close to people, but not over crowds. C1 requires an online course with an exam.
A2: You need a Class C2 drone and the A2 remote pilot certificate. As a rule, you must keep at least 30 m horizontal distance from uninvolved people. With an active low-speed mode, the distance may drop to 5 m, but only after assessing the weather, the performance of the drone and the shielding of the overflown area.
A3: There is no relief on distance to people here. The flight must take place in an area where no uninvolved people are endangered, and the drone must stay at least 150 m away from residential, commercial, industrial and recreational areas. C2, C3 and C4 are permitted, as are older drones without a label under 25 kg.

The mistake this produces in practice: a pilot who holds only the A1/A3 certificate considers every open area suitable. They launch 150 m from a house but right next to a park full of weekend visitors, and breach A3 because the park counts as a recreational area, not just the house.

The UAS zones are a legal requirement, not an extra feature

Under Royal Decree 517/2024 (Article 36), in general and special geographical UAS zones you must comply with the conditions and restrictions of each zone, and where zones overlap, the conditions of several zones apply at the same time. Among others, the decree mentions prohibition and restriction zones (defense and public security, environmental protection, photography restrictions), zones around military installations and critical infrastructure, and urban zones. According to the decree, information on temporary zones is provided in a uniform digital format. So check the zones in the official ENAIRE information and not only on a general map.

For airports and controlled airspace, ENAIRE names two types of zones. The first covers zones around civil and military aerodromes and heliports (Article 41). Flights there must be coordinated with the aerodrome operator or the air traffic service unit, and the dimensions are measured from the aerodrome reference point. The second covers controlled airspace and flight information regions (Article 42). No coordination is needed there if all three conditions are met at the same time: visual contact with the drone (VLOS), flight outside the zones under Article 41, and a flight altitude of at most 60 m above ground. If even one condition is missing, the flight must be coordinated with ENAIRE. ENAIRE shows concrete distances for a specific airport or heliport only in its maps and diagrams, so look them up there and do not derive them from a rule of thumb. A site that looks rural on a normal map can still lie inside such a zone.

Coordination runs through ENAIRE Planea, with a safety form and a risk assessment of the operation. ENAIRE points out that before operating you must check registration, remote pilot requirements, category and possible zone authorizations.

The drone's own geofencing does not replace the legal check

Another common mistake: many consumer drones have manufacturer geofencing that blocks or warns about takeoffs in certain areas. This function is set by the manufacturer, not by AESA or ENAIRE, and the two systems do not have to match. A place can be legally restricted while the drone's software gives no warning, or the other way around. "The app allowed the takeoff" is therefore no proof that the flight is permitted. The legal answer comes only from the official zone information.

Common mistakes worth avoiding

Assuming a drone under 250 g never needs registration, without checking whether it has a camera.
Treating the A1/A3 certificate as sufficient for any open area, without observing A3's 150 m distance from residential, commercial, industrial and recreational areas.
Skipping the zone check because a place looks rural, instead of clarifying whether an aerodrome zone or controlled airspace lies there.
Relying on the drone's geofencing warnings instead of checking the official zones, although the two systems do not necessarily agree.

Practical checklist

Clarify, based on weight and camera, whether your drone must be registered with AESA.
Determine which Open subcategory (A1, A2 or A3) your flight actually falls into, and have the matching certificate ready.
Check ENAIRE's geographical UAS zones for your exact coordinates before every flight, not just once for the general area.
Do not treat your manufacturer's geofencing as confirmation that a zone is legally clear.
Always check current requirements and the zones through the official channels of AESA and ENAIRE. This guide is orientation only and does not replace a flight permit or legal advice.
