CPDLC is a generic term for data link communications between pilots and air traffic controllers. You may also hear data link referred to as Future Air Navigation System (FANS) 1/A which, in addition to CPDLC, includes Automatic Dependent Surveillance–Contract (ADS-C).

The CPDLC module is designed for pilots flying internationally in aircraft with FANS 1/A avionics capability. The module is based on the following source documents:

  • ICAO Doc 10037 Global Operational Data Link Document (GOLD)
  • ICAO Doc 9869 Performance-based Communication and Surveillance (PBCS) Manual
  • Federal Aviation Administration (FAA) Advisory Circular 90-117 - Data Link Communications

The module includes the human factors associated with data link communications and Aviation Safety Reporting System (ASRS) reports by pilots with lessons learned on how to prevent errors.

The module includes CPDLC Departure Clearance (DCL) and Performance Based Communication and Surveillance (PBCS).

The CPDLC module can be included with the International Procedures curriculum for those crews using data link systems, or can be taken as a stand-alone module for crews seeking approval to use their system for the first time.


The module is designed to meet the training requirements for Ops Spec A056 on Data Link Communications.
The module is designed to meet the training requirements for Letter of Authorization (LOA) A056 on Data Link Communications. The module complies with the International Standard for Business Aircraft Operations (IS-BAO) training requirement for CPDLC defined in Chapter 13 of IS-BAO. The Business Aviation Safety Consortium (BASC) standard requires training when LOAs are issued for international operations.
