Seems every time someone hits the water we add another light and gadget to the panel. A rad-alt has been common on everything from Jetrangers to S92 flown offshore, but an ARA approach can still be flown without it. The NTSB recommendation is for EGPWS. So the next time that two pilots ignore the rad-alt, gear warning audio and light, both altimeters unwinding, both VSI negative for a long period, ground prox bar on the EFIS C+, AVAD, we are all confident and satisfied that they will notice the EGPWS. Maybe, maybe not since even those have the Offshore toggle so you don't lose your nav and radar at a bad time on an ARA approach. I don't think there has been a CFIT accident of a EGPWS equipped helicopter in the GOM yet. When there is, the NTSB will add some other warning to the panel for the pilots to not notice.
What about some proper CRM and CFIT training instead that is tailored to the offshore flying and to the aircraft systems and automation? Why do we waste a couple of days a year listening to some retired airline pilot drone on in a classroom about an Airbus hitting a mountain just to get that piece of paper that says "CRM"? What about SOP's that are written with helicopter IFR CRM and the automation in mind instead of treating them as two separate subjects?
