This paper presents the computational and experimental techniques associated with ground vibration test of very flexible aircraft (VFA) for nonlinear aeroelastic model development. It accounts for the suspension system and multiple deformed shapes about which modal characterization needs to be performed. The methodology is validated in a prototypical VFA.
