I fly from Ards and yeah, I'd agree always be sure you are cleared, and ask if you're not sure, even if getting a FIS.
Otherwise, just ask one of the instructors. They've always been very approachable to me, and have even said if you need to ask anything give them a call and if they're on the ground they'll do they're best.
Happy flying and I hope I'll see you around some day.
