Abstract: Provided are technologically improved systems and methods for reducing controller-pilot data link (CPDLC) rejection ratio on an aircraft. The system is programmed to receive a user provided tentative CPDLC request. The system receives traffic data from an external traffic data source and data from a navigation system and a sensor system. The system predicts whether the tentative CPDLC request will be accepted by air traffic control (ATC), based on the received data. The system further predicts a potential delay time until the ATC will accept the tentative CPDLC request. The system additionally provides one or more alternative CPDLC requests and their potential delay times when the system has predicted that the tentative CPDLC request will be rejected. The system displays this information and receives user selections based thereon. Upon receiving a user selection, a CPDLC request is sent to ATC in accordance with a predicted delay time.
