Interesting points IO540 - thanks for the information. I had not appreciated the full implications of the issue ref. the CAA restrictions over the JAA PPL rules. However, I was aware of the advisory nature of the approach limitations.
In reference to your point about IR issue for non-commercial pilots, I must say I would go for an IR like a shot, if I could afford it. The examinations are not an issue. Until such time as affordability also becomes a non-issue I am very glad to have an IMCR.
