This is requesting to add an option to keep settings configuration and flight data configuration the same so in the case you delete and re-install the app, or choose to play infinite flight from another device, you do not have to waste time going through settings at the start.
The same applies to the flight data configuration in the bottom of the screen when in flight.
This would be optional setting though as it may be that some prefer to have different settings and flight data configurations on different devices.
