The AGARD FVD panel, which for the last 20 years has sponsored activities in the field of flight vehicle system identification, decided in 1987 to set up the FVD working group 18, tasked with exploring and reporting on the topic of Rotorcraft System Identification. Using flight test data bases from three different helicopters, specialists from research organisations and industry applied their individual evaluation techniques for data quality checking and for the identification and verification of flight-mechanical models. The accomplishments of the Working Group are documented in the final report. This paper gives a broad overview on the basic identification methodology and the practical approaches. Representative results are given to illustrate the main identification steps: specific flight test maneuvers and required measurements, definition of appropriate model structures, application of identification methods,and verification of the results. The Working Group mainly concentrated on the determination of 6 degrees of freedom rigid body models. Based on the experience gained in the group, higher order models have recently been identified. Therefore, the paper also addresses the advances and gives an example for the application of the obtained models.
