The aim of this paper is the evaluation of several pilot models found in the literature, suited for helicopter pilot-assisted and\npilot-induced oscillations analyses.Three main topics are discussed: (i) sensitivity of rotorcraft-pilot couplings simulations on the\napplication of the different pilot models available in the literature; (ii) effect of vehiclemodeling on active pilotmodeling; (iii) effects\nof interactions between active and passive pilot models.The focus is on hovering flight, where a specific adverse rotorcraft-pilot\ncoupling phenomenon, the vertical bounce, may occur. Pilot models are coupled with a comprehensive aeroservoelastic model of a\nmid-weight helicopter.The numerical investigations are performed in frequency domain, in terms of eigenanalysis and frequency\nresponse analysis.
