Whats with the 'when the weather is bad or at night and the AA can't fly, there might not be a SAR helicopter available for overland poor wx tasking because the crews are civvy'????????
So what kind of special kit does SAR have since i left that allows it to fly in poor weather overland that a CIVVY AA not got? HEMS minimum flight rules are 300' cloud base 3000m viz...... would you want to be out in anything less than that?
