2) If IMC then must be IFR.
But a very special type of IFR: OCAS hence no ATC guidance, correct?
Which means not lower than 1,000' above highest obstacle within 5nm (of Track) of aircraft unless Taking Off or Landing in accordance with normal aviation practice. In IMC it is normal aviation practice to only land following published Instrument Approaches (and hence complying with their minima).
Got that.
So if I got that right it's exactly the opposite of the EASA E-IR:
IMCr: enroute OCAS IMC VFR, controlled IMC app/dep
E-IR: enroute CAS IMC IFR, uncontrolled VMC VFR app/dep
or did I mess up?
