Controller Pilot Data Link Communications (CPDLC)
Definition
Controller Pilot Data Link Communications (CPDLC) is a means of communication between controller and pilot, using data link for ATC communications. (ICAO Doc 4444: PANS-ATM)
Description
CPDLC is a two-way data-link system by which controllers can transmit messages to the pilot without the use of voice communications. The message is displayed on a flight deck visual display. CPDLC is an essential element of Automatic Dependent Surveillance (ADS)
Messages from a pilot may follow a standard format or may be free-form. Messages from a controller normally follow a standard format. Response is required to most messages.
Communication procedures are detailed in ICAO Annex 10 Volume III Part 1 Chapter 3. The CPDLC message set is contained in ICAO Doc 4444: PANS-ATM, Annex 5.
