Whilst on this topic if I may also digress a little....... how do others go when in VMC inside CTA and actually coming across IMC conditions? It *frequently* happens for me that I'm zooming along and very quickly come up upon some cloud and it sometimes happens quite quickly or I have time to go around it, but this would require loads of radio work on what may already be a congested frequency.
Would you just zoom on through it knowing that you'll come out the other side shortly?
Just keep going into temporary IMC, not mention it and not worry as you're not going to hit anyone / anything because you're in CTA under the assumption you'll come out the other side?
Would you call radar / centre and immediately ask for a change to clearance?
Make the diversion and then worry about calling when clear of cloud?
None of the above?
Hopefully this doesn't sound like a stupid question, but as I said it happens often as a VFR pilot in Vic around Melbourne and when you have to call urgently because you're only VFR it's like you're making a mountain out of a mole-hill.
