Peter R-B couldn't agree more.
That is exactly why I believe the importance should not be on a small amount of instrument "appreciation" during the new JAA PPL (asking for trouble when mixed with the wrong personality) but in fact a sensible CRM/Captaincy type course to prevent flying into those conditions in the first place.
We have it in the commercial world when will(or how many have to die before) the CAA decide that PPl's should also attend such courses as part of gaining their licence.
