A computer-implemented method for prioritized flight data transmission includes receiving a frame of flight data from one or more aircraft data sensors, the frame of flight data comprising a plurality of parameters collected from one or more avionics systems. Each parameter of the plurality of parameters is associated with a respective priority level. The method includes decomposing the frame of flight data into a plurality of flight data frame layers, each flight data frame layer of the plurality of flight data frame layers comprises a subset of the plurality of parameters having respective priority levels that are equivalent. A first flight data frame layer of the plurality of flight data frame layers comprising parameters having a highest respective priority level are transmitted to a ground station. A second flight data frame layer with parameters having a priority level lower than the highest level may be transmitted by a second transmission mode different from the first transmission mode. A system for implementing the invention may include a combination recorder line replaceable unit 242 including a real-time access recorder 240. The invention allows the effective use of communication resources by prioritising the most flight important data for transmission from the aircraft.
