Why do manufacturers design a hoist facility on their helicopters and market them as SAR aircraft if they know that any normal winching height for SAR is within the avoid curve? Sounds a bit irresponsible putting a facility in place that might encourage users to spend extended periods of time loitering in an area considered unsafe. Should the guy hanging underneath the helicopter take out extra insurance?
Or b) can it not be accepted that for the best to be got out of a helicopter's capability then sometimes its crew have to take the manufacturer's advice with a little pinch of salt?
