HeliComparator
You're right on the low occurrences of crashes due engine failures. My point is another.
The huge difference in flying aircraft like the 139 is not in the OEI performance (that are anyway outstanding) is the daily operation carried out in AEO conditions as I stressed in my post.
Safety in operations on helidecks are also provided by good AEO power margins, aircraft controllability, cross wind capability (45 kts at all azimuth for the 139) and possibility to carry out approaches, landing and take offs with the best obstacle clearance possible.
At AW we did not traded safety with range, on the contrary we have provided the highest safety standard with the best range capability in its class.
I hope you'll never brief your passengers that the aircraft are flying in has a very good range but some exposure in the most critical part of the flight!
