Pilots needs to be competent at operating the equipment they are provided with, particularly really important stuff like a radar. In 24 years of flying weather radar equipped helicopters I have never received any structured, formal training in the use of the radar, apart from watching a Honeywell radar training video, once. I don't even think we have radar questions in our recurrent exam question bank, and radar is not taught during initial type technical ground school. If this is widely common in the industry it needs to change. Maybe there should be a radar exam, much like a basic gas turbine exam before you're allowed to fly a turbine helicopter, with a logbook certification required.
