3. Why Controller Pilot Data Link Communications? Controller Pilot Data Link Communications (CPDLC) will provide data communications for Air Traffic Control (ATC) operations to supplement the existing air-to-ground (A/G) voice communications and support improvements in airspace use and capacity. CPDLC will: –Provide for a more dynamic and efficient A/G information exchange mechanism –Provide an additional means of communication between pilots and controllers –Reduce congestion on the voice channels which limits ATC effectiveness thereby reducing delays –Reduce operational errors resulting from misunderstood instructions and read-back errors

4. John Kern Data Link Issues Team Created by Jane Garvey’s NAS Modernization Task Force Objective: To develop a Federal Aviation Administration (FAA)/Industry plan for Aeronautical Data Link (ADL) evolution and implementation path with En Route CPDLC being the first project selected for review.

5. FAA / Industry Consensus Plan The consensus reached uses the following phased approach for developing and implementing ICAO’s standard En Route Aeronautical Telecommunication Network (ATN) compliant data link services: Build I (domestic CPDLC) Four ATN compliant operational services Use VHF Digital Link Mode 2 (VDL-2) as A/G Sub- network Build IA (enhanced domestic CPDLC) Increases ATN compliant services Use VDL-2 as A/G Sub-network

6. FAA / Industry Consensus Plan (Continued) Build II (domestic/international CPDLC) Increases ATN compliant services (more complex 3-4D messages and downlinks) Use VDL-2 as A/G Sub-network Build III ATN message set Integration with Decision Support Systems Use Next Generation Air/Ground Communications (NEXCOM) as A/G Sub-network
