FAQ n.115365

How can I determine if my aircraft is CPDLC multi-frequency capable?

Answer

Operators can check:

  • the AFM, which should contain a statement such as “The aircraft ATC Data Link system does support multi-frequency operation as defined in ARINC Specification 631-5.” or
  • directly with the type certificate holder (TCH) or with the supplemental type certificate holder (STCH) if the system was installed by an STCH. or
  • check the aircraft documentation for the indication that the system supports CPDLC multi-frequency operation (e.g. ARINC Specification 631-5 or higher)
