T he empennage, also known as the tail or tail assembly, is a structure at the rear of an aircraft that houses the horizontal and vertical stabilizers, which provide yaw and pitch stability to the aircraft during flight. EWIS cabling interconnecting flight controls, transitions via the aft pressure bulkhead, which protects the cabin interior volume. An Auxiliary Power Unit (APU) and firewall is also located within the tail assembly and is serviced with a broad range of both power as well as signal cabling.
