a) when a flight plan is available, verify that the aircraft identification, aircraft registration, and other details contained in the data link initiation request correspond with details in the flight plan, and where differences are detected make the necessary changes; or b) when a flight plan is not available, create a flight plan with sufficient information in the flight data processing system, to achieve a successful data link initiation; then c) arrange for the re-initiation of the data link process.

2.11.2.12.6.3 The aircraft operator shall establish procedures to resolve, as soon as practicable, initiation failures. Procedures should include, as a minimum, that the pilot: a) verify the correctness and consistency of the flight plan information available in the FMS or equipment from which the CPDLC communication is initiated, and where differences are detected make the necessary changes; then b) re-initiate data link. . . .
