Abstract

The planning and conduct of flight experiments is a critically important part of the system identification process. Factors such as the choice of test input signal and the duration of the experiment can have a major influence on the quality if the identification results. Other factors such as the quality of flight-crew and ground-crew briefings and the availability of on-line monitoring facilities also greatly influence the effectiveness of any flight testing programme. Inevitably there is a trade-off between performance and flight safety which must be taken fully into account at all stages of identification flight trials and influences the experimental design process and test matrix in a very significant way. Other important practical constraints arise in experimental design, especially when test input signals have to be applied manually by the pilot. The paper includes an outline of the forms of test input most commonly used for system identification and provides an account of methods of experimental design in which the value of a frequency-domain approach is emphasised.
