You wanna try applying app C to a typical bush sector in PNG...then do 10-20 sectors in a day, 6 days a week
The answers have always been the same...cubic gasoline and an escape route/plan b.
The first CP I ever worked for said to me on day 1...as soon as you lean forward in the seat and go

turn around.
Within the context a private operations flown by a PPL holder it seems to me that the divide between pure VFR and highly desirous/requiring an IR is a performance issue.
VFR is the domain of lower performance home built aircraft, Tiger Moths,Piper Cubs, smaller Cessnas/Pipers. By the time you're talking C210/A36 let alone C337/C310/B55/B58 etc you're talking a serious 'going places' aeroplanes...should they be flown by non instrument rated pilots?
Clearly there are VERY few ways to stop a VFR PPL with sufficient funds buying any damn aircraft he wants..except insurance coverage.
It is becoming more common in the US and I cant see it not happening here sooner rather than later...that is a current IR being
a requirement of coverage...or
at least the premium delta being
inordinately in favour of Instrument Rated pilots...sufficient to ensure the initial/recurrent IR training is
WAY cheaper than the extra insurance premium. Annual documented proof of qualifications/currency required for renewal.
This would likely remove this class of aircraft further from the grasp of the average PPL renter but so what? Precious few, and fewer every year, of these aircraft are available on line anywhere these days anyway.
There could be no argument that this chap couldn't afford an IR. If he was
rated and current would he have been scud running along a beach?
Even if he/she decided that was the only option...no IAL procedure at desto for instance...at least when it turned to terminal poo instead of trying a visual turn at dot feet with no horizon you go on the clocks, turn to a safe heading and climb out...and the skills exist to do that safely...as opposed to turning in over the beach and hitting a tree/hill/power lines/mobile phone tower...or the beach...a strip of sand/trees in low vis does not a horizon make...good one ATSB...again
