The migration of ACAS users ended in December 2016, and we then started to move Ascend Fleets users over to Flight Fleets Analyzer. One the features that Fleets Analyzer lacked, and that had been part of Ascend Fleets, was totals on the Summary pages. This was added during December, along with the ability to group by order date, as well as Total Period Utilisation on the Trend/Projection pages.
