FreeBird began as a biz jet and airliner only database. As time has worn on, and more helping hands have come on board, it has grown to include the many different genres of aircraft listed. More type data is being added to FreeBird on a weekly basis, to the extent that no estimate can be made as to where the total number of records will end.
FreeBird is designed by enthusiasts, for enthusiasts. To this end we include as much information as we think will be relevant to spotters or photographers. It is not a database that is aimed at, nor intended for, use within the aviation industry.
FreeBird is intended to be useful for enthusiasts on the move. Base information for business jets and turboprops is included, where known, to enable enthusiasts to make informed deductions while on spotting trips, particularly in the United States. Long lists of mispoles upon your return could be a thing of the past!
In a similar vein known fixed call signs, SELCALS and HEX codes are also included and searchable within the database.
All upgrades of FreeBird within the subscription year are included within the annual rate.
