Many of you have noticed the hollow arrow in the status bar after running AvPlan EFB 3.0. We have implemented a feature called Geo Fencing in the app. We now place a region around your departure airports in your flight plan, so when you reach 5 NM and are airborne, the app will automatically set your departure time and activate the next leg in your flight plan.
When the app is in the background you will see the hollow arrow. If you close your flight plan the geo-fences are deleted, and you will see no hollow arrow when the app is in the background. This does not consume any extra power on the device either.
