How reliable is the data?
The basic structure of the database guarantees that: • Each recorded or notated setting of a tune is linked to only one distinct tune. I.e., no tune setting, whether on a recorded track or in a book with numbered tunes, can be cited more than once within the entire database. I have also consistently held myself to the following rules: • The identity of every tune recording, and of every tune transcription in books with numbered tunes (e.g. “1001 #398”), has been verified (see next item) by me. I also guarantee my identifications of transcriptions in books which fail to include tune numbers (such as Cr, FF, or M2) if I provide at least a page number location. • “Personally verified” means that I never trust anyone else’s information about a tune, whether album liner notes, scholarly publications, or personal communications – although I may use those sources as leads for me to then verify.
I’d characterize it as “pretty good”. I don’t make any guarantees that the data is valid because I don’t have any control over it. It’s provided by the same data feed that feeds all other VATSIM data applications and that data feed has been known to go down occasionally, sometimes for hours at a time. Make sure you read the answer to question General-3 (right below this one) as well. I would not recommend using this site as VATSIM verification for virtual airline hour tracking systems, and make no claim or warranty as to its suitability for that purpose.
