Why Controller PilotData 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

John KernData 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.

FAA / IndustryConsensus 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

FAA / IndustryConsensus 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

FAA Investment Decision

• FAA Investment Decision on 10/30/98 – En Route CPDLC Build I (key site only)– En Route CPDLC Build IA (national deployment)

• Additional Investment Decisions required prior to beginning Builds II & III

En Route Controller Pilot Data Link Communications Build I Summary

• Single-site deployment– Key Site: Miami Air Route Traffic Control Center

(ARTCC)– Keysite Initial Operational Capability (IOC): 6/02

• Provides 4 operational services– Transfer of Communication– Initial Contact– Altimeter Setting– Informational Free text menu capability built by

supervisor inputs• Uses VDL-2 as A/G subnetwork• Includes Human Factors demonstration at

FAA Tech Center by 12/00• American Airlines will be the launch airline

En Route Controller Pilot Data Link Communications Build IA Summary

• National deployment to all 20 domestic ARTCCs

• Key site IOC: 6/03 Miami– National deployment– Begin installation: 1/04– Complete installation: 12/04

• Increase the message set to accommodate assignment of speeds, headings, altitudes as well as a route clearance function

• A capability to handle pilot-initiated altitude requests

• Uses VDL-2 as A/G Sub-network

• Anticipate widespread industry participation
