Where pilots from two or more countries race together without renumbering, there may be pilots racing with duplicate numbers. Handle this with a flexible input system that can handle both unique and mixed numbers, and accept input with either a prefix or a suffix (e.g. 808, SCO808 or 808SCO) with a warning prompting for a suffix if the number is not unique.
Continue to accept input if they fail to enter a prefix/suffix allowing correction later if a lot of pilots come through at once.
