Crab,
The right quality and amount of training will be crucial to the success of future SAR, a point that you have articulated on many occasions. However, what makes you think that civilian aviation will not allow the right amount of training. The amount of training available to both MCA and JIGSAW crews is certainly in line with that available when I carried out RN SAR (3-4 hours per day with content decided by a/c captain in conjunction with crew).
So the question is what makes you think that there will be a significant reduction in training available within the new SAR force - the precedence seems to point to this not being an issue.
