They don't have RIPS - I thought that was reasonably clear - obviously I need to work on my syntax.
Leaving an exercise is hardly making a restrictive decision about the crews capabilities. calling in a flight from the other side of the country to do a job in your own patch, is.
You keep forgetting that the whole concept of the new SAR service was that it would be no less capable - not by the end of the contract but at the beginning. The experience levels are rather variable; there is no LCR to CR syllabus and training budget to address that and the amount of training in role on the new aircraft seems thin.
