I am most interested in this thred, as I work for a company that makes the software to produce the loadsheets!
With the general industry move to centralised load planning, this is going to be an increasing issue.
A company who I worked for centralised their operation, and initially the crews kept asking the dispatcher to sign the loadsheet, as they would not accept the electronic signature. After a while, they got used to it, so it did not remain a problem.
I would be interested to hear other opinions.
