in this case as it should have been working it is "unscheduled" or unforeseen. because if it was scheduled maint' it wouldn't be occurring on a working day
I would have thought that the fact they have given advanced notice with the date and time of the maintenance - it must be considered scheduled.
I am going out on it on the 3rd (two days time) lets hope it managers to limp across!
Aaaaah, you see this is the dark secrets of maintenance speak. if it had been scheduled maint' then there wouldn't have been a sailing! as there was a sailing there couldn't have been scheduled maint'.
its like the space time continuum, can't have two similar bodies from separate universe's occupying the same space
Therefore, as the sailing has been cancelled and maint' carried out the maint' was "unscheduled" but is now scheduled. Hope this makes sense
