Drone licence in Spain: the A1/A3 and A2 exams

Flying a drone in the European open category needs a theory exam, and in Spain both open-category exams are run by AESA, the national aviation safety agency. They are free, they are online, and what they ask is set mostly by European law rather than Spanish law.

The two exams side by side

The forty questions, the 75 % threshold, the nine subjects and the five-year validity all come from Implementing Regulation (EU) 2019/947, which applies directly and which member states cannot alter. The forty-minute limit does not: the regulation sets no time limit at all, and AESA publishes that figure itself.

A1/A3: nine subjects

Air safety, airspace restrictions, aviation regulation, human performance limitations, operational procedures, general knowledge of UAS, privacy and data protection, insurance, and security.

AESA does not publish how the forty questions are distributed across them, so any specific breakdown you find is someone's estimate. Two of the nine — airspace restrictions and insurance — are filled with national law, in Spain mainly Royal Decree 517/2024. Those are exactly the two where study material from another EU country teaches you answers that do not apply here.

A2: three subjects, and a strict order

Meteorology, UAS flight performance, and technical and operational ground-risk mitigation. None of them appears in the A1/A3 list: the two exams do not overlap, so a question bank for one does not prepare you for the other.

The regulation lists the conditions for the A2 certificate "in the order indicated": pass the A1/A3 online course and exam, complete practical self-training in A3 operating conditions, then sit the additional exam. AESA enforces that as an admission filter — without proof of the A1/A3 training you cannot register for A2.

The A2 exam is remotely proctored with the SMOWL system on AESA's training platform, so the machine you sit it on must allow access to its webcam, microphone and screen.

You may be exempt from A2

If you already hold the remote pilot theoretical knowledge certificate for standard scenarios in the specific category, AESA's registration guide says the system detects it, exempts you from registering for and passing the A2 exam, and issues the A2 competency certificate automatically. Worth checking your file in AESA's electronic office before you study — or buy — anything.

Registration and deadlines

Registration goes through AESA's electronic office using Cl@ve or a digital certificate; people without either use the route provided for foreign nationals. Once access is granted you get 30 working days to complete the course and the exam. Miss it and the file closes with a withdrawal decision, and you start the registration again.

On "official question banks"

There is no publicly available official AESA question bank. Anything advertised as "the real AESA exam questions" cannot substantiate that claim. What can be substantiated is the source of each question, which is the approach we take: write the question from the regulation and keep the article it comes from stored next to it.

Our apps

Drone A1/A3 covers the nine subjects with 218 questions; Drone A2 covers the three with 122. Both quote the article behind every answer and both run mocks in the real format — 40 in 40 minutes and 30 in 30 minutes, 75 % to pass, no penalty. The questions themselves are in Spanish, because that is the language of the exam.
