Of course, the laws are actually really complex, but only applies to drones between 750 grams to 9 kilos, so mavic is excluded.
If you want to fly in a un populated area, you dont need to do anything diferent, only let know the dgac that you are going to fly there , but if it i in a populated area, its realy complicate:
You need to register your drone, and it must have a parachute, also you need a licence to fly, and you must have autorization from the dgac, also you must be have insurance, noy on your drone, against thirds.. and thats all
sorry about my bad english!
