“…For these reasons, FBW was initially the domain of large transport aircraft only. In 2005, the first business jet with FBW was introduced, the Dassault Falcon 7X, and later, for example, the Gulfstream aircraft (Hamel, 2017). However, all these machines still fall under the EASA CS-25 category.…”

The use of passive sidesticks in large transport aircraft equipped with Fly-By-Wire (FBW) has shown several problems related to the lack of force feedback. In the context of the current trend to find ways of introducing FBW systems also in small general aviation and future Urban Air Mobility vehicles, it will be necessary to address, how to control these machines and whether the adoption of passive controls from transport aircraft will be acceptable. This paper summarizes the benefits and challenges associated with the potential application of active sidestick in future small FBW aircraft.

“…This was for example the case for the first variable-stability helicopter, the NASA Langley HO3S-1, in the 1950's. The variable stability was achieved for the pitch, roll and yaw axes using a modified autopilot and tunable potentiometers [1]. An in-flight simulator goes further in the sense that it requires the capability to follow a given response-type in all axes and to frequencies up to typically 10 rad/s or more.…”

This paper presents the analysis of the fidelity obtained when performing in-flight simulations of the Bo-105 helicopter in forward flight with the Active Control Technology/ Flying Helicopter Simulator (ACT/FHS). The results are preliminary in the sense that they are based on the real-time and fully non-linear simulation model of the ACT/FHS in DLR's helicopter simulator and not in the ACT/FHS itself. Yet, a flight test proven controller setting is used in the simulations. The ACT/FHS, the model-based controller, and the command model are briefly presented. The precision of the MBC for each control/response axis is evaluated quantitatively through frequency-domain methods, time-domain methods and handling quality analysis. A perceived fidelity evaluation process based on piloted simulations and comparative flight tests with the Bo-105 is presented. This process is first applied to evaluate the model-following precision and second to evaluate the fidelity of the in-flight simulation. The results of the evaluations are used to identify strengths and weaknesses of the in-flight simulation for each response axis, including cross-couplings.
