Abstract: Digital recording and replay system for an aircraft, comprising a Mission Computer with an Operational Flight Program for generating instrument data for onboard instruments of the aircraft; a Mission Data Recorder connected to said Mission Computer for recording said instrument data; and a Mission Debriefing System; wherein the Mission Debriefing System is configured to reproduce the onboard instruments of the aircraft based on instrument data retrieved from the Mission Data Recorder. Method for reproduction of onboard instrumentation of an aircraft, comprising the steps of connecting a Mission Data Recorder to a Mission Computer of an aircraft having an Operational Flight Program for generating instrument data for onboard instruments; recording instrument data; providing a Mission Debrief System and causing it to reproduce the onboard instruments of the aircraft based on instrument data retrieved from the Mission Data Recorder.

Abstract: An aircraft communication system and corresponding method for establishing a datalink network between participating aircrafts, wherein each participating aircraft comprises a datalink transponder for sending and receiving standard communication messages (M) over a standard communication protocol; said datalink transponders are employed for establishing said datalink network using a standard communication protocol, and wherein said datalink transponders transmitting event driven messages (M) with a predefined structure identifying said messages (M) as test messages (TM) and at the same time comprising message data (MD) for establishing said datalink network, thus providing a datalink network established by transmission of solely messages (M) compliant with said standard communication protocol.

Abstract: An aircraft avionics system (10) for an aircraft, comprising includes a mission system (2), controlled by an open systems mission computer with a tactical communications system (320) and a tactical navigation system (220), The avionics system also includes a civil system (I), controlled by a flight management system with a civil communications system (310) and a civil navigation system (210), The mission system (2) is logically separated from the civil system (I) through separation of a navigation system (20) of the aircraft into a civil navigation system (210) and a tactical navigation system (220), and through separation of a communications system (30) of the aircraft (100) into the tactical communications system (320) and the civil communications system (310), and through the independence of the open systems mission computer from the flight management system, The separation allows the civil system (I) to operate and be updated independently from the mission system (2).

Abstract: Digital recording and replay system (100) for an aircraft, comprising a Mission Computer (MC) with an Operational Flight Program (OFP) for generating instrument data (ID) for onboard instruments of the aircraft; a Mission Data Recorder (MDR) connected to said Mission Computer (MC) for recording said instrument data (ID); and a Mission Debriefing System (MDS); wherein the Mission Debriefing System (MDS) is configured to reproduce the onboard instruments of the aircraft based on instrument data (ID) retrieved from the Mission Data Recorder (MDR).

Abstract: The wing has a structural part (15) and a separable complementary part (10) designed in a way that it can be mounted respectively dismounted in the structural part of the wing reproducing the form of a desired standard wing. Said complementary part constitutes at least partially a leading edge of the wing and comprises a space filled with an energy absorption material which constitutes a core (14) of said leading edge.

Abstract: Propeller-driven aircraft (30) comprising an engine (31) providing mechanical engine power for rotating a propeller (32), an engine limiting unit (35), an engine control unit (37) for controlling the mechanical engine power of the engine (31), a system (36) for measuring the airspeed and providing information concerning the airspeed to the engine limiting unit (35), wherein the engine limiting unit (35) automatically reduces the mechanical engine power at airspeeds below a certain first airspeed value (V1).
