Good advice thanks. I like the comment regarding individual considerations based on the mission. I will use that in future.
My next question then is......
"Why is the UK legal minima set at 3km for PPL without IMC (in Class G)"
Consensus here, albeit from a small amount of respondents, would seem to suggest that this minima is too low; since we are not happy to operate under these conditions. Would it not be more prudent to raise this minima as it could indicate to VFR only PPLs that flying in this viz is acceptable, even though a majority may not have the necessary skills and/or currency.
I realise that there are very experenced VFR PPLs who would be happy to operate under these conditions and maybe the minima is set to enable these more experienced folk to enjoy this whilst generally keeping the decision of acceptable personal minima in the hands of the PIC.
