A method and system for time-based viewing to coordinate airport collaborative decision making (A-CDM) events between a pilot and ground personnel on a cockpit display of an aircraft of generating a time scale with a list of A-CDM events of the aircraft during inbound, turnaround and outbound flight operations to an airport based sensor data contributed by aircraft systems and data of A-CDM event related to airport operations to generate a current time moving window in the time scale for identifying A-CDM events; generating a graphic user interface using the sensor data for positioning the current time moving window on the time scale; and collaboratively communicating with ground personnel decisions based on an aircraft state and a current A-CDM event identified by the positioning of the current time moving window in the time scale to expedite completion of a particular A-CDM event.
