Is the 50 hours training ringfenced for actual training? to give an example, NPAS (police) have very little allocation of training hours. The assumption is that the crews will gain almost all of their 'training needs' on the job. In fact the only training hours mandated are 4 hours annually per pilot for simulated instruments, along with 2 hours with a TRI testing and a further 2 hours base and line checks.
Now I accept that police flying and SAR flying are worlds apart at the delivery end (police crews will routinely do many jobs per shift), but with moves towards empire building in the future, management and regulators will push to use SAR jobs as training time just as police flying does.
