1 AERONAUTICAL INFORMATION CIRCULAR 15/14 IMPLEMENTATION PLANNING OF CONTROLLER PILOT DATA LINK COMMUNICATIONS SERVICES IN CANADIAN DOMESTIC AIRSPACE Introduction (Replaces AIC 34/13) On 16 December 2011, NAV CANADA commenced the use of controller pilot data link communications (CPDLC) within the Canadian Domestic Airspace (CDA), with services offered in the Montreal, Edmonton, Vancouver, Winnipeg, Moncton, and Gander (Domestic airspace) flight information region (FIR). It is the intent of NAV CANADA to expand CPDLC service into the Toronto FIR in early part of As with the services offered in the other FIRs implementation of CPDLC in the Toronto FIR will be via a phased approach, as detailed below. Purpose of Circular This circular advises operators of the service area coordinates and expected implementation timelines for the Toronto FIR. Specific start dates for each of the implementation phases will be announced via Notice to Airmen (NOTAM). A description of the implementation phases, flight crew procedures, and supported CPDLC messages are also detailed below. Note: Cette information est aussi disponible dans l autre langue officielle.

5 Vancouver Area Control Center The Vancouver CPDLC service area is FL 290 and above in the portion of the Vancouver FIR/CTA bounded by: N W Then west along the Canada/US boundary to N W to N 125 W to N 128 W to 51 N W to 54 N 136 W to N W to N W Then along the Canada/Anchorage (US) boundary to 57 N W to 56 N W to N 119 W to N W then west along the arc of a circle N W to 25 NM radius centred on Skookum, BC non-directional beacon (NDB) to N W to N W to N W to the point of beginning. Toronto Area Control Center On or after April 2014, the Toronto ACC will begin application of CPDLC in the Toronto FIR/CTA. The Toronto CPDLC service area is FL 290 and above in the portion of the Toronto FIR/CTA bounded by: N W Then west along Canada/US boundary to N 87 W to N 87 W to 50 N W to 52 N W to N 80 W to 49 N 79 W to N 79 W Then counter clockwise along the arc of a circle of 25 NM radius centred on Rouyn, QC NDB to N W to N W to N W to N W to N W to N W to N W to N W to the point of beginning.

6 Phased Implementation Phase 1 Basic Request Phase This initial phase will enable an aircraft to make various speed and altitude requests using CPDLC. The response from the ACC ground system will be a free text acknowledgement that the request has been received and that a response from air traffic control (ATC) will be provided by the appropriate ACC via voice. Phase 2 Advising Domestic Frequencies This phase introduces the assignment of domestic contact frequencies via CPDLC. Analysis of voice traffic indicates that such messages represent a significant proportion of existing voice traffic, and using CPDLC to carry out this function would be a useful contribution to reducing voice congestion. Phase 3 Support En Route Altitude Changes and Speed Changes This phase will enable aircraft to request En Route altitude changes, En Route speed changes, and to report Leaving/Reaching Levels via CPDLC. Responses to these requests from the ACC will also be via CPDLC. Phase 4 Full Implementation With the exception of those messages deemed unsafe by International Civil Aviation Organization (ICAO), specified downlink elements will be supported. Domestic ACCs will develop appropriate procedures to respond to all received downlink message elements. ATC will not provide information regarding when or where a flight can expect to climb or descend, due to the potential misunderstanding that such a message constitutes a clearance.

7 Supported Downlink Messages Supported downlink messages will be published via NOTAM. Any downlink message other than indicated in the NOTAM will generate a MESSAGE NOT SUPPORTED BY THIS FACILITY response from the ground system. Flight Planning Air traffic services (ATS) systems use field 10 (Equipment) of the standard ICAO flight plan to identify an aircraft s data link capabilities. For ICAO 2012 format flight plans, operators should insert the following items into the ICAO flight plan form for FANS 1/A-equipped aircraft: 1. Field 10a (Radio communication, navigation, and approach equipment): insert the indicator(s) J1 J7 to indicate appropriate data link equipment as per the table below. Field 10a Indicator Type of Data Link Equipment J1 CPDLC FANS 1/A ATN VDL Mode2 J2 CPDLC FANS 1/A HFDL J3 CPDLC FANS 1/A VDL Mode 4 J4 CPDLC FANS 1/A VDL Mode 2 J5 CPDLC FANS 1/A SATCOM (INMARSAT) J6 CPDLC FANS 1/A SATCOM (MTSTAT) J7 CPDLC FANS 1/A SATCOM (IRIDIUM) AERONAUTICAL INFORMATION CIRCULAR 15/14 Page 7 of 9

8 ATS Facilities Notification (AFN) Logon A CPDLC connection is initiated by the ground system in response to an AFN logon received from the aircraft. It is important, when initializing the flight management computer (FMC), to ensure that aircraft identification matches the identification displayed in the filed ATC flight plan message. If a flight becomes aware that incorrect flight identification data was provided in the AFN logon, the data link must immediately be terminated and a new AFN logon performed with the correct information. Flights entering any CDA CPDLC service areas from airspace where FANS 1/A ATS data link services are being received do not need to perform another AFN logon. Flights entering the CDA CPDLC service areas from airspace where no FANS 1/A ATS data link services are being received should perform an AFN logon: a) 15 to 45 minutes prior to entering the airspace; or b) prior to departure if departing airports are adjacent to, or underlying, the airspace. The AFN logon address for flights entering CDA facilities are as follows: Facility Name Montreal Area Control Centre Edmonton Area Control Centre Moncton Area Control Centre Gander Area Control Centre (Domestic) Gander Area Control Centre (Oceanic) Winnipeg Area Control Centre Vancouver Area Control Centre Toronto Area Control Centre Facility Identifier for AFN Logon CZUL CZEG CZQM CDQX (Domestic identifier) CZQX CZWG CZVR CZYZ Flights exiting the CDA CPDLC service areas into adjacent airspace where data link services are offered should not need to perform another AFN logon. Under normal circumstances, the current and next ATS units automatically transfer CPDLC and Automated Dependent Surveillance Contract (ADS-C) services. The transfer is seamless to the flight crew. Communication of CPDLC Service Capability CPDLC will supplement existing very high frequency (VHF) voice as modes of direct controller pilot communications (DCPC) or high frequency (HF) as a third party mode of communications, within CDA. Aircraft that are entering a Canadian Domestic CPDLC service area and have performed an AFN logon are not required to use the term C-P-D-L-C on initial check-in or in other radio-telephony communications with ATC. Contact with Aero Radio Flight Crew Where VHF communications is not available in CDA; pilots shall contact the appropriate Aero Radio station and on initial contact shall do the following: 1. Do not include a position report; 2. Use the term C-P-D-L-C after the aircraft call sign; 3. If required request the SELCAL check. The following is a sample exchange with Gander Aero Radio: GANDER RADIO, AIRLINE FIVE FIVE ONE C P D L C, FLIGHT LEVEL 350; REQUEST SELCAL CHECK FDAB Page 8 of 9 AERONAUTICAL INFORMATION CIRCULAR 15/14
