Fly near restricted areas

[Fran1520]

Hello. I'm looking for places to fly in Galway. But there is one thing I still don't quite understand. When I look at the airports on the maps for uas flights, I don't know if I can fly outside the radius of the prohibited zones or if I have to go 5km away from the airport. If so, I couldn't fly anywhere. If there is someone from Galway I would like to know in which areas I can fly there. Thank you
