It is a trueism that most twin engined helicopters do not operate to - lets call it Group A in old money - when taking off offshore. That is not to say that they cannot do it, they can but they will have to reduce their operating weight by a significant amount. The exposure times ecountered during a non Group A take off can be measured in seconds.
Lets wait and see the weight penalty that the '92 has to pay before we gasp in admiration.
