WHAT IS FANS 1?

Page 4: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1FIRST INSTALLATIONS ON 747-400 PROVIDED SIX SERVICES

• GPS NAVIGATION : RNP accuracy, Global time

• AFN : Air Traffic Facilities Notification

• CPDLC : Controller Pilot Data Link Communications

• ADS : Automatic Dependent Surveillance

• AOC : Airline Operational Communication

• RTA : Required Time of Arrival

Page 5: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1 : GPS NAVIGATION

• Global coverage from GPS satellites

• Coupled to Flight Management System

• Accurate - to RNP specifications

• Also provides global time reference– for navigation and ADS time stamping

The improved navigation capability brings operational benefits in its own right

• wider range of alternate aerodromes -> less alternate fuel• reduced ATC separations (based on RNP criteria)

Page 6: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1 : AFN

• AFN - Air Traffic Facilities Notification

• A process for flight crew to log on with their aircraft address to the initial ATC centre using that centre’s 4 letter ICAO identifier

• AFN logon provides to the ATC system the names, versions & addresses of airborne applications

• ATC handover can forward the aircraft address to the ‘next data authority’ (next ATC centre)

Page 7: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1 : CPDLC

• Controller Pilot Data Link Communications

• Predetermined standard message set

– defined in RTCA DO-219

• FANS 1 does not support all DO-219 messages

– some messages automatically arm/load the FMS

– some messages automatically extract FMS data

• Free text messages are also possible

Page 8: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1 : ADS• Automatic Dependent Surveillance

• ATC centre establishes ‘contracts’ with aircraft– periodic and ‘event’ triggered reports to ATC– future FMS points as well as present positions– use event contracts to assure conformance to flight plan

– rather than frequent periodic position reports

• On demand ‘one shot’ reports are also available

Page 9: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1 : AOC

• AOC = Airline Operational Communications

• Flight Plans, winds can be uplinked to FMS

• Flight Plan, position etc can be downlinked

• Plus requests up to crew, down to airline

• Reference - ARINC 724

Page 10: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FANS 1 : RTA

• RTA = Required Time of Arrival

• Allows crew to specify Required Time of Arrival at a waypoint

• FMS then controls aircraft to achieve this target

– 4D navigation : x, y ,z(altitude), t(time)

• Used in Australia with ATM tactical flow management automation - ATC gives pilot a time to arrive at a ‘feeder fix’

OPERATIONAL APPLICATION OF ADS• Position reporting

– Basic ADS reports

• Position extrapolation between position reports– based on Projected Intent, Earth Vector etc reports

• Automatic Flight Level monitoring– based on Vertical Event Contracts (with ATM system processing)

• Automatic Route Adherence monitoring– based on Lateral Event Contracts

• Automatic waypoint passing reporting– based on Waypoint Event Contracts (FDP automatically updated)

• Automatic Flight Plan Consistency (FLIPCY) check– based on readout from FMS of next two waypoints

Page 31: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

IMPACT OF ADS ON SEPARATION STANDARDS AND PROCEDURES

• ADS can be used in lieu of voice or CPDLC position reports

• ADS can be used to establish aircraft clear of crossing tracks

• ADS can be used to establish aircraft maintaining a level

• ADS can be used to monitor the new 50RNAV separation standard

• Work is proceeding towards introducing a 30NM separation standard

FREE TEXT WELCOME MESSAGE

The following free text uplink message is sent to each FANS 1 aircraft as it enters Australian airspace

“MSG_NO*169*ADS OPERATIONAL. NO FURTHER CPDLC POSITION REPORTS REQUIRED THIS FIR”

Page 55: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

AN ACTUAL CPDLC EXCHANGE

• UPLINK from ATC“MSG_NO*169*ADS OPERATIONAL. NO FURTHER CPDLC POSITION REPORTS REQUIRED THIS FIR”

• DOWNLINK response from pilot“MSG_NO*67*UNDERSTAND NO POS REP REQUIRED WHAT DOES CPDLC STAND 4 TQ”

HOW NOT TO USE FREETEXT

(a freetext route clearance request from Sydney to Los Angeles!)

“Flight No. Registration Sun Apr 23 01:04:05 2000MSG_NO*67*REQUEST DIR DOVOM.TERUX.S21E180.KILAN.DARMA.SAPIX.PASSA.QUIGG.SANTA.CANOL.BELAN.AHNDO.WEDES.LAX”

(Flight No. and Registration removed for anonymity - this is a real message received by Brisbane in April)

Page 57: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

HOW NOT TO USE FREETEXT

• Sending WILCO in freetext instead of using MSG 0 “WILCO” in response to an uplink

“Flight No. Registration Fri Jun 2 22:58:43 2000MSG_NO*67*WILCO”

• This response defeats the ATC system automation which may be programmed to use receipt of the MSG 0 “WILCO” to automatically update the flight data processing record. Freetext is not recognised.

Page 58: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

HOW NOT TO USE FREETEXT• Appending free text to the end of a position

report “Flight No. Registration Fri Jun 2 22:58:43 2000MSG_NO*48*POSITION REPORT*27*26.100MINS*S*157*54.200MINS*E*3H51M*320FL*HEELA*4H*7M*BEAGL*11H50M*-37Deg_C*266Deg*100kNOTS*0.84mACH*POVOP*3H*51M*320FLMSG_NO*67*REQUEST CLIMB FL340 TKS”

• The position report automatically updates the FDP; the controller probably missed the freetext on the end of the position report

Page 64: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

FLEXTRACKS

• Minimum fuel track between a city pair

• Recalculated each day using forecast weather

– Track Definition Message published

– aircraft may plan this route

• Used for some years Los Angeles - Sydney, Los Angeles - Auckland

Flextrack Savings

AIRSERVICES AUSTRALIA

DARPS(Dynamic Airborne Route Planning System)

• On Pacific long haul routes (14 - 16 hours), a new forecast can become available one or two hours into the flight

• A new minimum fuel route may offer benefits over the current flextrack

• The new route can be uplinked via datalink, downlinked as a clearance request, and if approved used to update both the FMS & FDP

• DARPS have been in operational use in the South Pacific since March 1999.

Page 67: Operational  Experience with FANS 1/A ADS  and CPDLC

AIRSERVICES AUSTRALIA

USER PREFERRED ROUTING• Each aircraft can plan an individually

optimised route• not only taking into account winds, but also the

individual aircraft weight, engines etc and airline operational choices

• Same datalink procedures as for DARPS

• Advanced ATM systems - ADS, CPDLC and Air Situation Display - support UPRs

• Pacific trials under way - presently suspended until after Sydney Olympics

Page 68: Operational  Experience with FANS 1/A ADS  and CPDLC

NEW ROUTES

• Los Angeles - Melbourne– not viable without FLEXTRACKS/DARPS

• The ‘Silk Route’ north of the Himalayas– only open to FANS 1/A aircraft– uses all aspects of FANS 1/A : C, N, S and ATM– shorter, greater access to preferred flight levels– time savings from 20 mins to 1 hour BKK <-> LHR

Group – Responsible for:

• ATN Transition Guidance Material

• ATN Transition Plan

• ATN Major Elements such as security, performance and system management

• AFTN Related Issues

• Planning and Implementation Information in the Air Navigation Plan - to develop ground ground part of the CNS Facilities And Services Implementation Document (FASID)

– Two Working Groups were formed to concentrate on producing a transition strategy and an ATN Topology for the Region

AIRSERVICES AUSTRALIA

CNS/ATM-1 ‘ACCOMMODATION’• FANS 1/A systems are in widespread use

• many aircraft, a number of ATM systems• many pilots and controllers now have significant experience

• FANS 1/A & CNS/ATM-1 will operate in parallel• CNS/ATM-1 ADS & CPDLC has differences from

the FANS 1/A implementation of ADS & CPDLC

• Existing ‘FANS 1/A controller HMI’ & ATM processing needs to be upgraded to accommodate both ‘flavours’

• Aim - upgrade to be ready when the aircraft arrive• Question - when will CNS/ATM-1 aircraft arrive in

the Asia - Pacific Region???
