Maybe the check list would be better to have a requirment to state the number of pumps on....ala.......13000 kg, 6 pumps on.
"13000 kg, 6 pumps on" That just rolls of the tongue as part of the checklist reading.
But will the pumps be ON? Maybe. Maybe not!
Checklists can lead to complacency. You merely read then respond with what should be set.
