Non PC Plod - yes there are some technologies that help but some that hinder - an example would be EGPWS in the mountains where all the alerts could be very distracting and lead you to either disable them or ignore them, both of which completely defeat their addition to the cockpit.
The problem is that you cannot remove all the risks from something like SAR - by its very nature you often have to fly in conditions that a normal risk and threat assessment would preclude, but if you don't launch, what is the point in you being there? Your only mitigation of risk is (hopefully) excellent training and superior CRM - some technology will assist as long as you are well versed in its use and have trained for such scenarios.
An example of what Super F describes would be NVD where weather deterioration is sometimes more difficult to notice and you can get yourself further into the high threat scenario than you realised.
