I may have confused myself here so I am digging out the old Jeppessen Instrument/Comm manual which I have no doubt will prove me wrong!!
Maybe you can still operate on an IFR plan but with respect to your IFR
clearance it has surely been cancelled/withdrawn. It is my understanding that should you wish to (or require to) re-enter IMC you will need a new clearance. To that end you are bound to visual flight (VFR)?? [US System]
If I appear to be having a "funny turn" and mixing up stuff I should know, please be patient!!
