The USA airplane data are downloaded from the FAA regularly.
Disclaimer: None of the data can be used for flight, they are for non-critical personal information only. Do not rely on these data in any way. The FAA is the primary authority as to the "real" information for all information regarding USA airplane registration data.
Instructions:Fill in as many the search conditions as desired. The search will return all records that match at least one string from each of the specified fields. To specify more than one string in a field, separate the different strings by semicolons. If you specify contradicting conditions (for instance Region: 5 (Alaska) and State: FL) you will get no entries back (any Unix style regular expression can be used here. This means that a "New" in the City field (without the quotation marks) will match New York as well as New Brunswick.) You have to first do the search with the Aircraft Search form to determine the exact models to look for, then use selected codes as input into the following Registration form.
Numerical fields can be searched with relative numerical expressions < (field is less than specified value), <= (field is less than or equal to specified value), > (field is greater than specified value), >= (field is greater than or equal to specified value), .. (the inclusive range operator, field is between lower and upper limit, inclusive. It has to be preceded and followed by a blank), and <> (the exclusive range operator, field is between lower and upper limit, exclusive. It also has to be preceded and followed by a blank).
For instance if you specify 100 .. 200, all entries with a value in that field between 100 and 200 will be returned. Specifying 100..200 (without spaces) will not work. You can specify multiple conditions in these fields too (e.g. < 100 ; >= 900).
If you get no entries back, it is probably because there are no matching entries in the database. This can be either because you mis-typed an entry or because you specified contradicting criteria, or there really are no registrations with the specified selection criteria.
If this sounds complicated, that is because it is complicated. You can do elaborate searches, but the more capabilities the search engine has, the more complicated it becomes. HINT: start with as few parameters as possible (add other parameters a few at a time to focus the search when needed).
