A detailed look at the design of jet engines with their bearings, lubrication and sealing reveals that jet engines leak small amounts of oil by design. This oil gets into the engine compressor and the bleed air. Almost all passenger jet aircraft today use this potentially contaminated bleed air for cabin ventilation.
Three methods for aircraft health monitoring and prediction are investigated: system monitoring, forecasting of time series and a combination of the two methods for combined monitoring and prediction. The methods use decision trees for decision making and use genetic optimization to improve the performance of the decision trees and to reduce the need for human interaction.

Support of design activities for innovative air conditioning systems in passenger aircraft. A model library based on the commercial standard software MATLAB/Simulink was programmed. The library contains simulation models of all relevant components that can be found in the air conditioning system and thermally relevant components in the aircraft cabin.
