Aerofly FS 2 offers you additional content you can buy like new airplanes and regions. Depending on your version you purchased, e.g. PC version from Steam or the mobile version on Apple iOS and Google Android, you have different options.
Under navigation you can select airports and navaids worldwide. You can add any waypoint worldwide.
To add more airfields select “Regions” from the main menu and buy the available region as In-App via your iTunes account. After logging in a confirmation of the purchase is needed. An installation of an In-App scenery needs enough free storage on your device. It is recommended to have 4 to 5 GB of free storage for a smoother performance on the device.
After an update or a new installation it may be necessary to restore the In-Apps once again. Please use the “Restore Purchases” button for this step.
More aircraft (In-Apps) can be purchased directly from the airplane selection menu. Aircraft that are not purchased appear slightly darker in addition with a green price button.
Tap on the purchase button to initiate an In-App purchase of the selected aircraft.
Doublecheck your prepaid credit on your iTunes account at first. Type in your password to login into your iTunes account. Then confirm the In-App purchase. Immediately thereafter you can fly the aircraft. Follow this link to manage your iTunes credit :https://www.apple.com/de/support/itunes/cards-codes/
