Visual – Beacons and Signage 2. Aural – Voice 3. Data-to-Text – A method communicating with an aircraft, while limiting voice radio traffic 3 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. Future Air Navigation System 1/A+ FANS 1/A+ . FANS 1/A is the suite of software upgrades that implement CPDLC, ADS- C, AFN and AOC communications over ACARS protocols. FANS 1 was originally developed by Boeing, while FANS A was developed by Airbus. The two systems are functionally identical so standardization efforts changed the naming convention to FANS 1/A. FANS 1/A+ added the message latency timer function 4 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. Future Air Navigation System 1/A+ FANS 1/A+ . Three components: 1. Air Traffic Facilities Notification (AFN) – aircraft logon to ATC Center 2. Controller Pilot Data Link Communication (CPDLC) – data link messaging for communications between air traffic controllers and crews 3. Automatic Dependent Surveillance – Contract (ADS-C) –contract based position reporting . Via data link over VHF (VDL Mode A or VDL Mode 2) or SAT (Inmarsat or Iridium) 5 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. GOLD Document Global Operational Data Link Document • ICAO's GOLD Document is a worldwide, collaborative effort to standardize Data Link procedures. It is the result of the progressive evolution of two documents: • The FANS 1/A Operations Manual, prepared initially by the informal South Pacific Air Traffic Services Coordinating Group (ISPACG); and • The Guidance Material for ATS Data Link Services in North Atlantic Airspace, produced by the North Atlantic FANS Implementation Group (NAT FIG), on behalf of the North Atlantic Systems Planning Group (NAT SPG) • Current: Second Edition dated 26 April 2013 • Next edition was planned for November 2016 6 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. Controller Pilot Data Link Communications CPDLC . CPDLC is a means of communication between controller and pilot, using text messaging via data link for Air Traffic Control (ATC) communication. The CPDLC application has three primary functions: . the exchange of controller/pilot messages with the controlling ATC authority . the transfer of ATC authority over that aircraft and downstream clearance delivery . or the opportunity of adjacent ATC centers to view the aircraft reports . Pre-defined message set, with free text if required . Replaces verbal ATC instructions and crew requests over radio frequencies reducing frequency congestion . Communication via data link significantly reduces receive and read back errors 7 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. Automatic Dependent Surveillance - Contract ADS-C . ADS-C is a contract between a ground ATC system and the aircraft using various systems on board the aircraft to automatically provide aircraft position, altitude, speed, intent, and meteorological data . ATC establishes the reporting period and information requested in the ADS-C Contract and up to 5 ATC Centers can monitor the aircraft simultaneously . Avionics report contracts as established by ATC with no intervention from the flight crew . Replaces position reports by HF radio reducing frequency congestion . Types of ADS-C reports: Periodic, Demand, Event and Emergency 8 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. FANS Logon and Handoff Process 9 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. Human Factors Considerations . Increased “head down time” for flight crew. Flight deck Human Machine Interface limitations and issues. Time required for reading/interpreting uplinks. Time required for selecting/composing/sending downlinks . Maintaining a shared crew awareness of the progress of ATC data link communications. Situational awareness and the inability of pilots to monitor other data link transmissions in the area of operations. 10 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information.

All rights reserved. Proprietary Information. Let’s talk paperwork Performance Based Communication and Surveillance . AC 90-117 Data Link Communications for U.S. Operators (LOA) . PBCS assures CPDLC and ADS-C perform to desired ATM levels. PBN complements but is not PBCS : – PBN: deals with RNP/RNAV criteria allocated to aircraft/operator – PBCS: deals with RCP/RSP criteria allocated to ATS/CSP/aircraft/operator . By 29 March 2018 U.S. Operators must submit a new A056 – Indicate whether or not PBCS is desired to be used – Indicate performance level (e.g. RCP240/RSP180) – Otherwise seize data link ops 17 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. Definitions of RCP/RSP • Required Communication Performance (RCP): The RCP Transaction Time defines the maximum time required for the completion of the transaction after which the initiator should revert to an alternative procedure. • Required Surveillance Performance (RSP): The RSP Surveillance Data Transit Time describes the time required for delivery of surveillance data in seconds. 18 | © 2017 Rockwell Collins. All rights reserved. Proprietary Information. PBCS Monitoring . Required as per Chapter 6 of AC 90-117 . Review the PBCS monitoring results for your aircraft at https://www.faa.gov/air_traffic/separation_standards/PBCS_Monitoring/ . Results indicating failure . Follow directions to remedy .
