Tail numbers are the numbers painted (generally) on the tail of an airplane. In this case the alphanumerics you entered into MSFS ATC Id when you load an aircraft from the menu. Underway! uses this to determine a valid loadout of your aircraft. Your callsign (via FSInn) is different and not used by Underway!

    Sorry for the delay in updating, we were busy putting out "fires". We are working on an FS-X only version of Underway!.
