Z-11, a light utility helicopter served for civil and military applications, is designed and developed by our own country. It is the first type of helicopter with the intellectual property rights independently owned by China, but also the first type of helicopter certified to full-cycle airworthiness management.

Z-11 is the light utility six-seat helicopter of two-ton class. The helicopter is designed with the conventional main rotor system as well as tail rotor.

Z-11 had successfully accomplished the flight test for civil airworthiness on Qinghai-Tibet Plateau at the end of 2002. Many flight tests are internationally acknowledged as Class I risky flight programs. These items have filled the gap of flight test area of indigenous helicopter in eight aspects, such as the in-flight starting testing and autorotation testing etc. It had realized the significant breakthrough in the flight history of the indigenous helicopter.

Z-11 has established many new national records in helicopter’s flight history of China, and it maintains the highest availability rate during the recent years. By the end of December 2005, the safe flight for the in-service Z-11 fleet has accumulated up to over 40,000 hours and 230,000 take-off and landings, and the availability rate exceeds 95%. Because of the perfect safety, no safety accident had ever occurred.

In January 2000, Z-11 created many records in the flight history of national helicopter during the flight tests in the high-altitude and extreme cold area. Flight endurance in air is more than 5 hours, and flight endurance lasts two hours under －38℃; ferrying flight time in a day is 8 hours and 33 minutes, and the temperature difference ranges between 5℃ and －38℃, and there is no failure detected during its 1332-kilometer flight, what’s more, after the continuous two days’ ferry flight for 2470 kilometers, and the helicopter is still in the perfect condition in the wake of crossing over 7 provinces,. Each performance index has reached the advanced level of the international counterpart’s helicopter. Z-11 is the only “credit-winning” helicopter type among these helicopters developed by indigenous industries of China with the shortest development duration and best in-service performance.

The company has been varying and modifying Z-11 to meet the needs of national defense construction and domestic civil market. So far the company has various models available for Z11, such as Z11 Police Helicopter, Z11 Armed Helicopter, Z11 MB1 Helicopter, Z11 Aerial Relay & Photographing Helicopter, and Z11 Power line Inspection etc.
