This FAA order can be considered the ATC bible. It contains all of the rules and regulations for controllers, however it can be hard to read and clumsy to navigate. The master outline can be considered a VATSIM specific version of the 7110.65. This will be the most common reference in this document. This order is updated every 6 months and is available at http://www.faa.gov/air_traffic/publications/atpubs/ATC/INDEX.HTM
