Algorithmen zur automatischen 4dimensionalen Flugbahnführung unter Berücksichtigung der momentanen Windsituation

Für das digitale Flugführungssystem des Versuchsflugzeugs HFB 320 wurde am Institut für Flugführung der DFVLR in Braunschweig eine Betriebsart zum automatischen zeitgenauen Fliegen im Flughafen-Nahbereich entwickelt und im Flugversuch erprobt. Der Bericht enthält die Beschreibung der eingesetzten Algorithmen zur Berechnung 4-dimensionaler Flugbahnen unter Berücksichtigung der momentanen Windsituation. Es werden verschiedene Verfahren zur Messung, Filterung und Vorhersage des Windvektors entwickelt und an Hand von Flugversuchsergebnissen diskutiert.

Automated generic integration of flight logbook data into aircraft maintenance systems

The automated transfer of flight logbook information from aircrafts into aircraft maintenance systems leads to reduced ground and maintenance time and is thus desirable from an economical point of view. Until recently, flight logbooks have not been managed electronically in aircrafts or at least the data transfer from aircraft to ground maintenance system has been executed manually. Latest aircraft types such as the Airbus A380 or the Boeing 787 do support an electronic logbook and thus make an automated transfer possible. A generic flight logbook transfer system must deal with different data formats on the input side – due to different aircraft makes and models – as well as different, distributed aircraft maintenance systems for different airlines as aircraft operators. This article contributes the concept and top level distributed system architecture of such a generic system for automated flight log data transfer. It has been developed within a joint industry and applied research project. The architecture has already been successfully evaluated in a prototypical implementation.
