Hello friends.
I would like to help with this information.
I put it on another topic but I think you can see more here since luckily many of you visit us.
The exam is free A1 / A3 and A2.
Digital signature is required (the simplest thing)
Another way is “pin key” or “permanent key”
First they have to register as a UAS operator
It is also free.
This is the access
https://sede.seguridadaerea.gob.es/AESA_UAS/
Once this process is done, they can access the registration for the A1 / A3 exam.
When they have approved they can access the A2 registration
Here they have access
https://www.seguridadaerea.gob.es/es/ambitos/drones/formacion-pilotos-a-distancia-uas-drones/formacion-de-pilotos-uas-drones-en-categoria-rabiertar
I have only read (not studied) course A1 / A3 and I passed with 9.25.
The A2 certificate is difficult, but I studied it very well and I passed with a 9.
Once approved, you will receive a notification in your email to download your certificate (pilot card).
If you need help, you can ask me.
