Used to do this for Canada 3000 before they went bust.
It took a while for the computerised loadhseets to get approved.
The crew were still required to do a manual loadhseet based on the manual load detail form info that was provided.
A copy of the Manual Loadhseet, Computerised Loadsheet and Manual Load Detail From had to be submitted for every flight during the trial period to the airline/Transport Canada for evaluation. Once they were eventually satisfied then the computerised loadhseets were approved. As I say it took a while for the approval - somewhere between 6 months and a year if I remember right.
It's back to the old fashioned way at the moment of manual load detail forms.
