OCTA Separation Minima in IMC
I'm wondering if anyone can provide me with references to indicate what the minimum separation standard is while OCTA in IMC. For example, the minimum vertical separation whilst more than one aeroplane is in a holding pattern. Also interested in horizontal separation.
People seem to have extremely varied ideas about what the minimum safe separation is, and I've never seen anything in the AIP or regs to suggest that anything is actually mandated.
With that in mind, I would also be interested to hear what other people's ideas about separation are when operating OCTA in IMC.
