The safe use of aircrafts can only be guaranteed when appropriate damage assessment is available. The last years, interest in structural health monitoring systems for composite materials of the aircrafts based on optical fibre sensors is increasing. Structural health monitoring (SHM) is the automated damage detection in engineering structures by sensor networks. Since the last two decades, the literature on SHM is exponentially growing. After basic and applied research, some applications came to the market and nowadays, they are on the way to be a standard in engineering structures, such as chemical plants, oil pipelines and bridges. The applications of SHM in aircraft industry such as in airplanes and in helicopters are however, still in an experimental phase. There are different reasons for this: Lack of technical maturity: Solutions proposed so far only solved isolated problems of an otherwise complex system, difficulties to match all natural environmental conditions, measured data are difficult to interpret due to the complex nature of aircraft parts. Lack of acceptance by end-users: Complicated and long-term certification process expected, scepticism against new technologies, pessimistic expectations concerning the return-of-investment. The lack of acceptance by end-users can be overcome by convincing technical solutions that respond to all the challenges inherent to aircraft operations. The major problem already mentioned in the list above is the difficult interpretation of measured data obtained in complex aircraft components.
