Summary:A nacelle assembly for a high-bypass gas turbine engine (10) includes a variable area fan nozzle (42) in communication with a fan bypass flow path (40). An actuator assembly (56) is operable to move a second fan nacelle section (54) relative to a first fan nacelle section (52) to vary a fan nozzle exit area and adjust fan bypass airflow. The actuator assembly (56) extends at least partially into the fan bypass flow path (40).
