Abstract: A communication method for satellite-based communication for an aircraft/spacecraft includes monitoring the availability of a first satellite-based communication system, and transmitting aircraft/spacecraft data via the first satellite-based communication system or a second satellite-based communication system depending on the availability of the first satellite-based communication system.

Abstract: A communication system for satellite-based communication for an aircraft/spacecraft with data memory, which is configured to store aircraft/spacecraft data during operation of the aircraft/spacecraft, a communication device, which is configured to communicate with at least one satellite-based communication system, and a control device, which is coupled to the data memory and the communication device and is configured to output aircraft/spacecraft data stored in the data memory during operation of the aircraft/spacecraft via the communication device.

Abstract: Described is a method for transmitting continuously created data items from an aircraft to a receiver. The data items are of a plurality of data types and each have a different priority. For each data type a live LIFO buffer and a main LIFO buffer are provided. In a regular operation mode continuously created data items are continuously stored in the main buffers. In a transmission operation mode continuously created data items are continuously stored in the live buffers, consecutive data packets are transmitted and for each data packet the data is selected from the buffers, wherein data items stored in live buffers are transmitted before data items stored in main buffers and data items of higher priorities are transmitted before data items of lower priorities. Further, a transmitter and an aircraft are described and claimed.

Abstract: A method for triggering a plurality of emergency measures associated with an aircraft emergency is disclosed. The method includes determining a risk level for an aircraft emergency by evaluating a plurality of flight parameters and/or aircraft parameters using a predefined logic. For each emergency measure of the plurality of emergency measures a threshold is defined and each emergency measure of the plurality of emergency measures is only triggered if the determined risk level exceeds the threshold defined for the emergency measure. Further, a system for use onboard an aircraft for triggering a plurality of emergency measures associated with an aircraft emergency and an aircraft comprising such a system are disclosed.

Abstract: A method for triggering a first emergency measure associated with an aircraft emergency comprising the steps of determining a risk level for an aircraft emergency and triggering the first emergency measure if the risk level exceeds a first threshold for the first emergency measure is described and claimed. The risk level is determined by evaluating a plurality of flight parameters and/or aircraft parameters using a predefined logic. The first threshold is adjusted according to a position of the aircraft over ground. Furthermore, a system for use onboard an aircraft for triggering a first emergency measure and an aircraft comprising such a system are disclosed.
