The tail numbers view lets you edit the tail number dropdown list. Typically, the dropdown lists in the logbook and detail views are filtered based on the current aircraft. On this page, you can set the aircraft associated with the tail number. By leaving the aircraft field blank, the tail number will appear in all dropdowns. An example of this is the "Unknown" tail number in the database by default. It has a blank "Acft" property so it appears in all dropdowns regardless of the filter.
NOTE: Changes to this page are not reflected in past entries, including the tail number text AND the associated aircraft. You must change entries manually.
