AvPlan EFB saves the track flown to the flight plan you were operating at the time.
If you wish to review the flight track, locate the flight plan in your Stored Plans list and tap on it to open.
To make sure that the track is displayed on the map:
tap the Map Settings button
place a tick next to the Show Aircraft Track option.
NOTE: If you put a flight plan back in Stored Plans and tap Discard Changes, the track log will also be discarded. To keep the track log, ensure you tap Save Changes.
Also, if you had AvPlan Live Tracking Enabled, there will be a copy of your track saved to the AvPlan servers. You can access it from inside the app by tapping in Settings/Flight Logs and selecting the flight you are interested in.
If you don't have AvPlan handy, you can use a browser to go to https://live.avplan-efb.com and sign in with your AvPlan credentials. All your flights will be there, along with a some other handy tools.
