Integrated controller-pilot datalink communication (CPDLC) systems and methods for operating the same are disclosed. In one implementation, an integrated CPDLC system includes a plurality of CPDLC-enabled avionics devices and a CPDLC context manager coupled with each of the plurality of CPDLC-enabled avionics devices. The CPDLC system further includes a shared CPDLC context memory coupled with the CPDLC context manager and a CPDLC message in/out buffer coupled with the CPDLC context manager.
