Aircraft Bluebook, the long-running aircraft price digest, has launched into the 21st century and is available online. Yearly subscriptions are available to complement the
CD-ROM and print versions. The book, which has been published for more than 50 years, allows users to determine the current market value of business aircraft based
on specific equipment and age factors. The current database contains more than 3,000 aircraft model variations, as well as values for avionics, de-ice equipment and engines. For those with more long-term interests, market trends are also included.
