Introduction of Enshi Xujiaping Airport?

Enshi Xujiaping Airport (IATA code: ENH, ICAO code: ZHES) started construction on 1986, and the new airport was completed and delivered on 1993+065438+ 10, located in Enshi, Hubei. The airport is designed by the Central South Airport Design Institute of Civil Aviation, and the 22nd Engineering Company of the Ministry of Nuclear Industry undertakes the track project. The airport is 495 meters above sea level and 4.5 kilometers away from the urban area.

Enshi Xujiaping Airport has secondary radar display system, VOR/DME navigation system, ILS/DME instrument landing system, and is equipped with supporting communication equipment such as north-south station and automatic relay system. The weather forecast is equipped with advanced equipment such as 7 18 digital weather radar and automatic observation system. At the same time, it is also equipped with a full set of navigation AIDS imported from the United States. The existing fixed assets are 200 million yuan. The construction and development of Enshi Airport has filled the airspace blind area of nearly 500 kilometers on several important air routes in China, which is of great significance to the development of aviation industry.

The development of history

Enshi Xujiaping Airport was built at 1986. The design model is Yun Qi He 'an 24, and the runway length is1800m.

1992 was approved by scaa [1992]16 and the Central South Bureau of Civil Aviation [1993]5 1, and the runway was rebuilt and expanded. The designed take-off and landing model was B-737(200).

1993165438+10, the newly-built xujiaping airport was opened to traffic, and Enshi airport entered the ranks of 3C airports, but there were few flights and small planes, which still could not meet the needs of the airport itself and local economic development.

1 997 65438+1October 18 successfully completed the flight test of B-737, and obtained the 4C-class airport license for aircraft below B-737 on1month 1998. Due to the complex terrain around Enshi Airport, and the runway is on the ridge, the east, south and north sides of the runway are steep, and there is no more surplus runway length. In fact, it only meets the take-off and landing of aircraft below Yun Qi. According to the test flight of the B-737 crew, the psychological burden of the crew is very heavy when the plane takes off and lands. In order to fully satisfy the safe operation of B-737 aircraft, the runway must be extended.

Enshi Airport has China Southern Airlines and Hainan Airlines operating Enshi-Wuhan route, and Huaxia Airlines operating Enshi-Chongqing route, with Boeing 737-700, Boeing 737-800, CRJ200 and other models. More than 20 flights have been opened to and from Wuhan, Chongqing and other places every week, with an annual passenger throughput of more than 200,000 passengers. Enshi Airport has also built a star-rated hotel integrating air ticketing, passenger catering, accommodation, entertainment and fitness, which can accommodate more than 0/00 passengers.

1997-2006, after 10 years of intensive expansion, the airport finally obtained 4C license and opened flight B-737, ending the history that Enshi Airport could only take off and land small planes. At the same time, it also broke the ice that has plagued Enshi aviation market for many years with high fares and even hard to find a ticket. Enshi Airport has routes such as Wuhan, Guangzhou, Yichang and Chongqing. There are nearly 60 flights a week, and the daily passenger throughput reaches 1.300 passengers.

In 2008, the target of 300,000 was exceeded. In addition, Enshi Airport also actively develops non-aviation industries, and civil aviation hotels have sprung up like mushrooms after rain, creating another source of income for the growth of the airport. At the same time, the airport system has also changed accordingly, and it has become a secondary unit with independent legal personality of Hubei Airport Group. Throughout these 50 years, the scale of the airport has grown from small to large, the flight conditions have improved from poor to good, the passenger flow of flights has grown from small to large, and the non-aviation industry has grown from scratch.

20 10 expanded again. The flight area of the expanded Xujiaping Airport is 4C, and the designed take-off and landing model is B737-800. The existing runway extends 250 meters to the north, reaching 2600 meters and 50 meters wide; A new apron with an area of about 6.5438+0.6 million square meters will be built on the north side of the existing apron, with a total of 8 apron seats and a combined model of 8c; The construction area of the new terminal building is 1 1,000 square meters. The new terminal is connected with the existing terminal through corridors to form a complete passenger hub system, which can meet the demand of 800,000 passengers in the first phase of the target year of 2020.

Equipment and facilities

The secondary radar made in Italy was installed in Xujiaping Airport, which was installed in the tower and regional dispatching center. There are also two sets of VOR/DME imported from Australia and Italy, and ILS/DME produced in Tianjin, which are equipped with north-south convergence station, north remote station and non-directional beacon, automatic relay system, satellite phone and other supporting communication equipment; The weather forecast is equipped with advanced equipment such as 7 18 digital weather radar and automatic observation system. At the same time, it is also equipped with a full set of navigation AIDS imported from the United States. The existing fixed assets are 200 million yuan. The construction and development of Enshi terminal has filled the blind area of nearly 500 kilometers airspace of several important routes in China, which is of great significance to the development of aviation industry.

Air tracking blind landing system

On June 5, 2009, 5438+1October 5, 2009, the instrument landing system (also known as blind landing system) completed by Enshi Airport passed the acceptance of the National Civil Aviation Administration and was officially put into use. This means that in the future, the inbound and outbound flights of Enshi Airport will basically take off and land all day.

Due to its unique geographical location and climate characteristics, Enshi Airport is always affected by low clouds and heavy fog, and flights are often delayed or cancelled. 128 October, 165438+ successfully passed the industry acceptance of China Southern Bureau of Civil Aviation, Hubei Airport Group Corporation and China Airport Construction Company. With the opening of the system, the navigation support capacity of Enshi Airport has been greatly improved, and the dependence of aircraft take-off and landing on weather conditions has been greatly reduced, which has provided a strong guarantee for passengers' travel safety.

Airport structure

The approach road foundation of Enshi Xujiaping Airport consists of two layers. The subbase is 150 mm thick and filled with gravel with particle size less than100 mm. The subbase is 200 mm thick and is planned to be filled with a mixture of gravel, red sand and lime. It is required that the density d of the mixture is greater than 2.30g/cm3 and the resilience modulus E0.4 is greater than 1 10 MPa. Through rolling test and theoretical analysis, a group of curves with general d and related parameters are obtained. According to this set of curves, the mixture ratio of Xujiaping airport base course mixture is determined as follows: crushed stone: red sand: lime = 1: 0.032: 0.035. The selected mixture ratio has been put into practice. The measured results at the base: D is 2.30 g/cm3 ~ 2.42 g/cm3, and E0.4 is115mpa ~ 414mpa, all of which meet the design requirements.
