THE LARGEST FAMILY-OWNED BUSINESS AVIATION SERVICE CENTER IN THE WORLD
DISCUSSION TOPIC In the early 1980s, the International Civil Aviation Organization (ICAO) became concerned with the aging infrastructure and the inherent faults with traditional Air Traffic Management (ATM) methods. In an effort to increase aircraft safety and limit the amount of human error, ICAO developed a council to investigate ways to increase safety. This council was charged with studying new technologies and operational concepts for the future of ATM and Future Air Navigation Systems (FANS).

DEFINITION WHAT IS FANS? Future Air Navigation System FANS-1/A is a format of communication for position reporting and text messaging Aeronautical Telecommunication Network (ATN) FANS 1 was originally developed by Boeing and later adopted by Airbus as FANS A The system uses an early version of the protocol that airlines have used for 15 years FANS comprises two parts: ADS-C: Automatic Dependent Surveillance Contract Up to five links CPDLC: Controller Pilot Data Link Communication One link at a time
DEFINITION WHAT IS ADS-C? Automatic Dependent Surveillance Contract (ADS-C) Also known as Automatic Position Reports Requires no pilot interaction ATC controls the reporting system (contracts) Can control up to five separate ATC contracts at any one time Different types of contracts: Periodic ATC can set and alter the update rate as needed a higher update rate is usually required in high traffic areas Event if there is a change in Vertical Rate, Lateral Deviation or Altitude Demand ATC can request a one-off update as needed. This does not affect an existing contact preset rate
DEFINITION WHAT IS ADS-C & CPDLC? Fourth contract type is unlike previous three Initiated and cancelled by the pilot not the controller In an emergency, it s automatically triggered by the MAYDAY message Controller-Pilot Data Link Communication (CPDLC) The messages and responses sent by ATC and the flight crew occur one link at a time Hint: Think of it as text messaging between pilots and ATC
IMPORTANCE OF FANS-1/A RVSM reduces the vertical separation of aircraft. The goal of ADS-C is to reduce separation of trailing aircraft from 100 nm laterally and 10 minutes trailing to 30 nm laterally and five minutes trailing Potential reduction of congested frequencies Oceanic Tracks: best equipped equals, best served No need to write down clearances Reduces risk of miscomprehension
SAFETY SERVICES Data FANS-1/A is considered Safety Services Data Voice Allows the ATC to contact the aircraft through the SATCOM and vice versa Records the conversation through the audio panels for the CVR Telephone handset does not meet this requirement Safety Services Voice is through the Inmarsat I-3 network, not I-4 and will not be on Global Express KA network. (SBB trials start in 2013) Currently not certified for use as primary ATC voice (certified as backup only; HF must be primary) Iridium does not currently comply

CERTIFICATION REQUIREMENTS Retrofit market FANS implementation Wide equipment variances in aircraft Multiple STCs required based on aircraft type WAAS FMS required for both FANS and ADS-B MCDU for FANS, C145 GPS for ADS-B Just like RVSM, there will be a multiple-step process for FANS certification Aircraft equipage Crew Training Letter of Authorization (LOA) required
ADVISORY CIRCULARS AC 20-140B
ADVISORY CIRCULARS AC 20-140B C159a requirement for Iridium added in the A to B update No Iridium unit is compliant yet ICG obtained compliance through DO 262A under 20-140B. They showed the appendix requirements under DO 262A were repeated from the Inmarsat system and many did not apply
ADVISORY CIRCULARS - NO FAA REQUIREMENT YET AC 120-70B
HOW IT WORKS AERONAUTICAL FACILITIES NOTIFICATION (AFN) LOGON The pilot triggers the initial AFN logon Sends an AFN contact message (FN_CON) containing the 4-character ATS unit ICAO code. ATS system responds with an AFN Acknowledgment message (FN_ACK).
HOW IT WORKS AFN LOGON The pilot triggers the initial AFN logon Sends an AFN contact message ATC sends logon acknowledgement
HOW IT WORKS CONNECTION REQUEST Connection Request ATC initiates request via ATS Unit The aircraft confirms and establishes connection
HOW IT WORKS CONNECTION REQUEST Connection Request ATC initiates request via ATS Unit The aircraft confirms and establishes connection
HOW IT WORKS NEXT DATA AUTHORITY (NDA) NDA The purpose of the NDA message is to advise the avionics of the next ATS unit that will make a CPDLC connection The NDA message is the first step in the CPDLC transfer sequence between an aircraft and two ATS units
HOW IT WORKS ADDRESS FORWARDING Address Forwarding Invisible to the flight crew For AFN logons initiated by the address forwarding process, the flight crew has no indication that the FN_CON or FN_ACK messages have been delivered successfully
HOW IT WORKS FMS CONTROL DISPLAY UNIT (CDU) SCREEN ATC Logon/Status Page CPDLC log on
HOW IT WORKS DIFFERENT NETWORKS SITA and ARINC networks simplified
HOW IT WORKS ADS-C POSITION REPORT ADS-C position Report
