With this post, I stress that I'm not making any any specific assumptions regarding this particular accident.
However, I've got a question regarding taking off in fog in civilian circles. In the UK military, the IF take-off is still taught to, and practiced regularly, by all helicopter pilots. It is regarded as an essential operational skill.
Is the IF take-off taught in civilian IR training? Is so, are there any currency requirements? If not, how does a pilot learn and retain those skills?
