Hi Eric,
interesting did read that same story yesterday, but main issue was as
well, that the status was unclear between different stations on the ship
which caused the issue that one station wa scontrolling the left engine
and the 2nd station the right one (wonder in what situation this would
be needed) I think it is down to a team without any real operation
experience designing a system 
But true and behold not everithing we love on our tablets will work in
another environment 
Cheers Werner

Some predict that most of the ‘systems’ will eventually change back to previous ‘control’ methods away from ‘touch’ screens.
Years ago the control by deviation allowed hundreds of process controllers to be monitored by just a few people. Basically a red pointer showing from behind the green area on the controller display was reason for an employee’s attention.
A study by the military (led by my Son [FAA employee]) determined the control by exception was preferred rather than reading number digits requiring the mind to decide if that was normal or not.
This retired GE process control tech (over 30+ yrs experience) has not welcomed touch screens and their digital displays from the beginning. I hope that the change back comes sooner rather than later.. Earl Schroeder.
