I have recent experience flying with experienced GOM pilots who were largely ignorant of IFR operation and procedures even though they were flying IFR helicopters. When I aked why they avoided clouds like the plague I was told that the only time they fly IFR is in the sim. The company discouraged any IFR flying due to costs and diversion fuel/weight penalties incurred.
The difference between North Sea and GOM offshore operations is enormous and I was staggered at the prevailing attitude in GOM. I also attended a CRM course there which lasted all of 30 minutes.
Re-equipping to multi-pilot IFR machines is not the cure-all either. The Bell 206 single-pilot VFR mentality needs to change too and judging by my experiences they have a very long way to go.
