An inlet system for an auxiliary power unit includes an inlet duct, and a frame coupled about the inlet duct. The frame defines an opening configured to be in fluid communication with the inlet duct. The inlet system includes a door having a first end opposite a second end. The door is coupled to the frame at the second end. The door is configured to move relative to the frame between a first position in which the door cooperates with the frame to inhibit airflow into the inlet duct and a second position in which the door is configured to enable the airflow into or out of the inlet duct. The door defines a ramp at the second end. A hook is spaced a distance apart from the ramp to define a gap configured to enable the airflow into or out of the inlet duct in the second position.
