Hi everyone. Am about to venture into LAANCsville for the first time and I am wondering how, if my iPhone is set to Airplane Mode, the Authorities can get hold of me while I am flying should they need to? As I understand it I shall have to give my U.K. mobile number when I seek approval to fly here in Naples FL Controlled Airspace but we are advised to have Airplane Mode switched on when we fly-I always do and if that’s on how do ATC contact me while I’m flying to warn me about something needing my air space? I may have this all wrong but am keen to comply everywhere.
