Geoff:
The interesting part of zorab64's post is the reference to the additional equipment - no prizes for guessing who is leading the debate on that.
The interesting item will be VHM; will that be just tail rotor monitoring or the transmission as well. If a helicopter is already equipped with FDR, this is not such an issue - with a FAR/JAR 27 helicopter it looks like the start of a new era.
The main issue - if these are to be replacement helicopters - will be the footprint on the helideck. A large plus point for all of these small twins is that they can provide zero exposure operations from small GOM decks.
