Helicopters pilots are warned of the circumstances under witch a Loss of Tail Rotor Effectiveness may be encountered. The present paper focuses on the modeling of the aerodynamic phenomena that can participate to a better simulation, even available for training, of tail rotor aerodynamic environment under the EUROCOPTER HOST code.
