Do you not think the customer paying for two possibly 80K+ pilots might not expect a little better prior planning as you mention, more situational awareness, and less complacency? They certainly seem to be the party describing these WDL's as unacceptable.
Another piece of machinery possibly .... but which code, which name - ICAO, IATA, maritime or FMS ..... plenty of scope there for error as well. Rig plate photos showing the actual markings are a help - as ever the Mk 1 eye-ball still acts as the final defence at present .... markings, helideck crew in position etc?
