Having been working offshore for the last 12 years and travelled in all sorts of helicopters I was recently in a S76C+(+?) in the GoM and the PFD seemed to be saying we were cruising at 150+ kts!
Having usually cruised along at a leisurely 120 kts in Bell 412's etc I was a surprised/impressed and wondered if TAS or groundspeed was being displayed? (we were ~600ft AGL).
Good to get there quicker.....but is getting to a rig faster a good thing.
