piston gone,
Yes the rules of the air do say that, but in THAT part they do not say the ratings required for this.
My previous post gives the exact reference from the ANO, schedule 8, which explicitly states that without an IR or IMCR, the minimum vis for a PPL is 3Km.
That schedule also gives the min vis. under SVFR for non IR/IMCR as 10Km, but 3Km with IR/IMCR.
Please read all of pages 2 - 5 in Pooley's, especially p5.
