That's what I would have said. But then I looked it up in AIP and it didn't say what I expected and now I don't understand. AIP ENR page 1.4-9 says VFR in Class E requires continuous 2 way communication.
What is "Continuous 2 way" radio communication? I fly around in Class G listening on Area, but I would not call that 2 way. My understanding of 2 way is that ATC must be able to direct communication to you specifically via your call sign and know you are listening i.e. it requires a check in. That is spelled out explicitly for Class D.
Or are different definitions of 2 way communication used for Class E and Class D, and e.g. IFR in Class G?
