A method for transmitting continuously created data items from an aircraft to a receiver, wherein the data items are of a plurality of data types, wherein each of the plurality of data types is assigned a different priority ranging from a highest priority to a lowest priority, wherein last-in-first-out buffers (1, 3, 5) are provided for storage of the continuously created data items, wherein for each data type a separate live buffer and a separate main buffer are provided and associated with the respective data type and data items of a specific data type are only stored in the associated buffers (1, 3), wherein in a regular operation mode continuously created data items of the plurality of data types are continuously stored in the associated main buffers, wherein in a transmission operation mode • continuously created data items of the plurality of data types are continuously stored in the associated live buffers, • consecutive data packets are transmitted from the aircraft to a receiver via a data transmission link, each data packet comprising a header section and a payload section, and • for each data packet the data to be transmitted in the payload section is selected from the buffers (1, 3, 5), wherein any data item stored in a live buffer is transmitted before any data item stored in a main buffer, wherein of those data items stored in one of the live buffers, any data item of a data type having a higher priority is transmitted before any data item of a data type having a lower priority, and wherein of those data items stored in one of the main buffers, any data item of a data type having a higher priority is transmitted before any data item of a data type having a lower priority. wherein last-in-first-out buffers (1, 3, 5) are provided for storage of the continuously created data items, wherein for each data type a separate live buffer and a separate main buffer are provided and associated with the respective data type and data items of a specific data type are only stored in the associated buffers (1, 3), wherein in a regular operation mode continuously created data items of the plurality of data types are continuously stored in the associated main buffers, wherein in a transmission operation mode • continuously created data items of the plurality of data types are continuously stored in the associated live buffers, • consecutive data packets are transmitted from the aircraft to a receiver via a data transmission link, each data packet comprising a header section and a payload section, and • for each data packet the data to be transmitted in the payload section is selected from the buffers (1, 3, 5), wherein any data item stored in a live buffer is transmitted before any data item stored in a main buffer, wherein of those data items stored in one of the live buffers, any data item of a data type having a higher priority is transmitted before any data item of a data type having a lower priority, and wherein of those data items stored in one of the main buffers, any data item of a data type having a higher priority is transmitted before any data item of a data type having a lower priority. • continuously created data items of the plurality of data types are continuously stored in the associated live buffers, • consecutive data packets are transmitted from the aircraft to a receiver via a data transmission link, each data packet comprising a header section and a payload section, and • for each data packet the data to be transmitted in the payload section is selected from the buffers (1, 3, 5), wherein any data item stored in a live buffer is transmitted before any data item stored in a main buffer, wherein of those data items stored in one of the live buffers, any data item of a data type having a higher priority is transmitted before any data item of a data type having a lower priority, and wherein of those data items stored in one of the main buffers, any data item of a data type having a higher priority is transmitted before any data item of a data type having a lower priority.
