Yes, you did require training. More than 50 hours per month per unit (ie ten hours per month per person). And you needed training in a variety of different disciplines by day and by night.
If it's modern risk matrices that Geoffersincornwall wants to bring into it to try and quantify the unquantifiable, multiply (ambulance paramedic with next to no time on helicopters) by (civilian pilot who has never worn a set of NVG before but will be required to do so operationally on April 1st) and see what you get. Alternatively, multiply (a pilot that's never hovered over the water at night without a close external reference) by (the remainder of the crew not having the SAR experience to know which jobs merit the extra risk and which don't). Finally, increase by a factor of 1.5 if you only have 10 hours of training available to you per month and that training is restricted by rules like not being able to live winch with the torques above a certain figure.
