My understanding is that the system that the company wants (jeppesen) is not just a software upgrade but a whole new system.
Therefore,it is not just an add on but a seperate entity.The problem is not just what they say it can do but what they can use it to do.
When the company was pushing the bid system they told us a number of things that turned out vastly different to what we were led to believe.
Be wary of anyone advising us to do something before the EBA has expired.
