can go wrong
I have actually trained people on this system frequently and I can assure you that both Swissport and Aviance insist that before any staff member would be given a login code for this system it is required that they first understand all the principals of Manual Weight and Balance, actually to an inexperienced loadcontroller there are many potentials for Mr cockup unless you have been thoroughly trained on it, and cockups do occur to those who have been given a twenty min run through, so I would reccomend that this is not policy, yes it is simple on the surface, but I have known many to make mistakes who are not experienced.
