This is the real Lufthansa EFB wallpaper that can be found on Lufthansa's Microsoft Surface in the cockpit of A320 Family aircraft. The pack also includes color customizations on the home screen and in the entire EFB in the Lufthansa color scheme, as well as Lufthansa real checklists.   This pack is compatible with A319-WTF, A320-WTF, A320-SL, A321-WTF and A321-SL. However, you must have purchased the A320-SL or A321-SL to be able to use the EFB on A319-WTF, A320-WTF and A321-WTF.
