Right this whole thread confused me somewhat, in terms of the actual definition of IFR (I couldn't really follow the idea of flying IFR in VMC
).
I have it sorted in my mind now, or will do shortly. In case anyone's having similar trouble with definitions, the (UK) ANO and rules of the air is available from the CAA at
http://www.caa.co.uk/cap393
IFR is defined in section 2.VI
Time for some fun reading now!
