ATC versus AOC
ATC
•FANS Protocol
•Defined Messages
– CLIMB TO AND MAINTAIN [altitude]
– CROSS [position] AT [speed]
•95% within 60s
AOC
• Free text
• Multiblock Messages
– 1,000 characters
• 777, 787, A380 generates many multiblock messages
• No time requirements

FANS Flight Crew Procedures
• Section 5 of the Global Data Link Document (GOLD)
• Overview
• Logon
• Uplinks
• Downlinks
• Automatic Dependant Surveillance
• Position Reporting

FANS Flight Crew Procedures
• Overview
• Data Link requires different flight procedures between the pilot flying and pilot not flying than are used for voice (very important)
• Internal training program for FANS and integration with LOFT
• Requires operational approval from state authorities
• Operational approval enables regulators to ensure operators
have an adequate training program and that the training program follows GOLD procedures.
• When to use CPDLC and when to use voice communicaitons

FANS Flight Crew Procedures
• Logon
• Unlike ACARS to establish a CPDLC connection the flight crew must “Logon” to an ATC facility to establish a CPDLC connection
• Procedures cover logging on when on the ground, after departure, and when entering a FANS capable FIR
• Procedures also cover automatic “handoffs” between FIRs and handoff failures
Flight Deck, Flight Crew Operations Research & DesignPage 704/10/23
FANS Flight Crew Procedures • Uplinks
• Once a CPDLC connection has been established CPDLC messages can be exchanged between the aircraft and ATC
• Each ATC data link (CPDLC) uplink message is annunciated to the flight crew using an aural and visual indication
• Unlike voice communication CPDLC requires BOTH flight crew to read the uplink silently to maintain situational awareness
• If reports are requested by ATC they should be responded to using CPDLC preformatted report messages not FREE TEXT
• Crew training material should highlight and develop special procedures for use of Conditional ClearancesNote: The Boeing 787 has a built in conditional clearance monitor function and the Boeing 777 has a crew
reminder function that can be used to remind crew of conditional clearances

FANS Flight Crew Procedures • Uplinks - continued
• Free Text has been and continues to be a problem with flight crews.
Each operator’s training program should highlight and remind flight crew’s on the use of free text.
• Preformatted messages should be used AT ALL TIMES in stead of typing out the same message using Free Text
Flight Deck, Flight Crew Operations Research & DesignPage 904/10/23
FANS Flight Crew Procedures • Downlinks
• Once a CPDLC connection is established the flight crew can create and send a “downlink” ATC message by using the pre-formatted
message pages.
• Preformatted messages should be used AT ALL TIMES in stead of typing out the same message using Free Text
• To avoid potential ambiguity, the flight crew should avoid sending multiple clearance requests in a single downlink message
