CPDLC - U.S. Domestic Only
U.S. domestic enroute CPDLC is now available to all appropriately equipped aircraft as of November 2023 [Ref: Federal Aviation Administration (FAA) Advisory Circular AC 90-117]. Training is not mandatory, but operational information is necessary on how to effectively use CPDLC in CONUS airspace. There is new guidance associated with updated and/or new operational authorization.This module is for aircraft that are FANS 1/A approved, equipped with VDL Mode 2 with Multi-Frequency and "Push to Load" (PTL) capability. Aircraft must also meet avionics requirements per the FAA En-Route CPDLC Participation List, file the corresponding equipment codes, and only log on to the system if they intend to participate. Voice remains the primary means of communication.
Authorization for domestic data link communication (CPDLC) use is no longer required for operation under any 14 CFR part; however, A056 authorization is still required for international and oceanic data link operations while U.S. Domestic CONUS data link operations will no longer be reviewed on A056 applications. All operators are responsible for knowing individual avionics capabilities and FAA domestic airspace datalink communications requirements. Operators may conduct U.S. Domestic data link communications where aircraft are properly equipped, the data link service is available, and airspace requirements are met.
The CPDLC U.S. Domestic Only module is NOT for operators seeking A056 LOA or Ops Spec authorization for Data Link Communications (outside the US). This is a training module for operators wanting to use CPDLC only in the lower 48 United States.
