Since we switch to a PED as EFB it has to be allowed. Said EFB (iPad Air) can be used for private functions as well as long as we leave enough space for the required company software on it, no tracing of usage or private functions is allowed so the company doesn't know what we do with it. Private use is allowed during non critical phases. Bluetooth to third party items is not allowed, however an aircraft iPad connection via bluetooth will be rolled out soon to allow ownship position and use of datalink/ACARS functions via the iPad.
