For the first time cabin displacement ventilation (CDV) has been tested under flight conditions in a passenger aircraft cabin. We were able to validate the expected advantages of CDV in a reconfigured part of an A320 aircraft. A cabin flight test and a CDV installation, suitable for static as well as dynamic ground and flight tests were developed. Pure CDV provides low air velocities and turbulence levels, a high heat removal efficiency and a very good dynamic performance. Providing 30% of the total volume flow rate through the lateral outlets in a hybrid system allows for still comfortable flow veloci-ties and good heat removal efficiency, yet im-proves the temperature stratifications and the cooling and heating rates at the cabin surfaces. Both systems provide a very homogeneous tem-perature distribution among the different seat positions.
