In-Flight Simulators (IFSs) require flight controllers, which mimic other aircraft's dynamics in a certain operation range, which is the problem addressed in this paper. The design problem of a linear parameter-varying type gain-scheduled flight controller, which simultaneously suppresses gust effect and reproduces low-and-middle frequency commands as IFS's motions in a certain speed range, for the lateral-directional motions of an airplane is addressed via linear matrix inequality formulation. Our controller performance is examined by flight tests.
