This paper presents the studies and conclusions of incorporating a novel morphing rudder for a commercial transport aircraft from the certification conditions perspective. This study provides the static directional-lateral stability evaluation of a two jet engined wing podded commercial transport aircraft when changing its conventional rudder configuration to a more aerodynamic efficient morphing configuration. The lateral force at morphed rudder deflection is set to increase 15% in relation to conventional configuration. The analysis is focused on the engine-out condition at take off which is critical for certification purposes.
