We’ve recently introduced flight plan messaging, which is being rolled out for all users at the moment. When your IFR flight plan has been accepted, you will get a message on your device(s) that ATC have received your plan. In addition we send you your expected routing as well. If ATC change your flight planned route, you will see this message and can be ready for the new routing when you call for a clearance.
AvPlan EFB 5.0 (coming in March) will have these revised routing available under Planning, Submit Flight Plan.
