some people are talking about Vmini and Autopilot, Vmini is 50KIAS, the AW139 has so many different phases of software and since this was an older machine the FD won't work below 60KIAS even the GA (if you can find it) button won't work, later phases you can enage the FD at 50KIAS and the GA button works at 41KIAS.
reading the transcript you can see from the moment they left PBI there was no CRM at all.
So sad.
