Actually I thought that the restrictions on flight under IFR outside controlled airspace and night VFR in certain Member States were legacies of either WW2 or the Cold War? Basically, the only traffic which couldn't be readily identified by interceptors had to be in a controlled environment?
Regarding FCL.600, Whopity is indeed correct. I've been pointing this out to the CAA for over a year now, hence another reason for the amendment to FCL.600 IR - General as proposed by IAOPA (Europe) and the UK CAA in their comment responses to NPA 2011-16. Which simply call for the inclusion of the existing provisions of JAR-FCL 1.175(b) into the Aircrew Regulation - hardly very contentious.
