Future Air Navigation System (FANS 1/A+) is the product name given to a suite of software upgrades that support CPDLC, ADS-C, AFN and AOC communications over ACARS protocols. FANS-1 was originally developed by Boeing, while Airbus originally developed FANS-A. The two systems are functionally identical. Industry standardization efforts sought to refer to both packages simultaneously, hence the naming convention “FANS 1/A”. The “+” came about as a minor update to the industry standard, DO-258 to DO-258a, and is primarily due to the new message latency feature in CPDLC. All FANS 1/A or FANS 1/A+ messages can be sent over Inmarsat or Iridium satellite systems in addition to VHF (VDL Mode 0, Mode A, or Mode 2.).
As requested by our clients, Kobev offers shortened recurrent training sessions for live practice of FANS login, and CPDLC messaging for refreshment training just before your next FANS flight
