New York Oceanic (KZWY) Controller Pilot Data Link Communications (CPDLC) Service Area
On March 20, 2003 at 1200z, New York ARTCC will be implementing full FANS1/A CPDLC capability in the New York Oceanic FIR MNPS airspace including that additional airspace within the New York Oceanic FIR south of 27 degrees North latitude and east of 60 degrees West longitude inclusive. CPDLC will not be available in the WATRS area. FANS-1/A capable aircraft that wish to participate in CPDLC may utilize this service. The New York Oceanic FIR log-on address is “KZWY”.
As KZWY does not have the capability to receive waypoint position reports using ADS, pilots should send their required position reports utilizing CPDLC. MET reports will not be required from flights when utilizing CPDLC.
EXCEPTION: Flights operating along A700 within MNPS airspace are not to use CPDLC and are to continue using HF voice.
1. HF Communications Requirement
Prior to entering the KZWY CPDLC service area, contact New York Radio on HF or VHF and identify the flight as CPDLC equipped; provide SELCAL, departure point, destination, and aircraft registration number. Expect to receive primary and secondary HF frequency assignments from New York Radio for the route of flight within the CPDLC service area. Pilots must maintain HF communications capability with New York Radio at all times within the entire New York Oceanic FIR.
2. Log-On (Entry Procedures)
Aircraft entering the KZWY CPDLC service area from NON-CPDLC airspace:
Initial log-on from non-CPDLC airspace: Log on to KZWY at least 15 minutes but not more than 45 minutes prior to entering the KZWY CPDLC service area.
Initial log-on in transit eastbound through WATRS airspace: Log on to CPDLC at least 15 minutes but no more than 45 minutes prior to entering the KZWY CPDLC service area. Continue normal ATC communication via HF voice until entering the KZWY CPDLC service area. Commence CPDLC communications at the service area boundary. Downlink messages sent prior to entering the CPDLC service area will be rejected and a response of "Service unavailable" will be uplinked.
EXCEPTION: Flights operating along A700 within MNPS airspace are not to use CPDLC and are to continue using HF voice.
Aircraft entering the KZWY CPDLC service area from adjacent CPDLC airspace:
Until further advised, there will be no automatic transfer of a flight’s CPDLC connection from any CPDLC service area entering KZWY. If a “Datalink Termination” message is received, pilots must manually log-on to the KZWY CPDLC system and send a boundary waypoint position report.
If “KZWY” is not the active center within 5 minutes after the boundary is crossed, pilots shall ensure all open uplinks from the previous ATC unit have been responded to, then terminate the CPDLC connection and log on to KZWY.
While “KZWY” is the active center the pilot shall ensure HF communications are maintained as a backup and begin CPDLC communication.
3. KZWY CPDLC Service Area Exit Procedures
Aircraft exiting the KZWY CPDLC service area to adjacent NON-CPDLCairspace (Santa Maria, Piarco, San Juan, WATRS, New York Center, Bermuda Radar, Moncton, and Gander Domestic):
Aircraft approaching the airspaces above can expect the CPDLC “CONTACT” message containing the frequency for the next facility. CPDLC will be terminated approximately 10 minutes prior to the boundary crossing point.
Aircraft exiting the KZWY CPDLC service area to adjacent CPDLC airspace (presently only applicable to Gander Oceanic):
Aircraft approaching adjacent CPDLC airspace above can expect the CPDLC “MONITOR” message containing the frequency for the next facility. CPDLC will be transferred approximately 10 minutes prior to the boundary crossing point.
4. Position Report Message Format
KZWY cannot accept position reports containing latitude and longitude (Lat/Long) in ARINC 424 format (e.g. 4050N). Position reports containing Lat/Long waypoints within the KZWY CPDLC service area will be accepted in whole latitude and longitude format only. Flights unable to send position reports in whole latitude and longitude format must accomplish position reporting via HF voice communications.
5. Controller Pilot Data Link Communications (CPDLC) Failure
In the event of CPDLC failure, flight crews shall contact New York Radio via HF voice for routine communications. SATVOICE contact is limited to distress and urgency situations.
