Ⅰ.Introduction

The Founding of Chinas Civil Aviation in 1949 opened a new chapter in the development of Chinas civil aviation. With the rapid development of the civil aviation， various flight problems have followed one after another. The normal rate of flights has stagnated， even dropping from 83.12% in 2007 to 68.33% in 2015. In 2016， it rose to 76.76%， while in 2017， it dropped again to 71.67%. In 2018， the normal rate of flights in China reached 80.13%. The problem of flight delay has become the focus and difficulty in the development of civil aviation.

The aviation industry in developed countries such as the United States started earlier and its operation system is more mature than that in China. However， flight delays are inevitable. The main research on flight delays is as follows：1.Tax policy on flight delays， Robin explained that the flight delays in the United States vary according to tax policy.2.Cost of delay： In 2010， Michael Cynthia Bahat conducted a comprehensive assessment of the cost and impact of flight delay losses， and the final result was very convincing .

The rapid development of Chinas aviation industry has made flight delays more and more prominent. Xie Yunshuang based on the compensation measures for domestic flight delays， have thoroughly explored the factors that lead to flight delays and completed the analysis of the economic impact of flight delays on airlines.Liu Guangcai deeply analyzed some of their existing solutions to the problem of flight delays. And they drew lessons from and learned from foreign measures to deal with flight delays， and pointed out the suggestion that China should start from the root to solve the problem of flight delays.

Ⅱ.Analysis of Causes of Flight Delay

Flight delays are caused by a variety of factors. According to the data released by the Civil Aviation Administration of China， the average normal rate of flights of Chinas national passenger airlines in 2017 was 71.67%， while among total factors causing flight delays， airlines ，air traffic control and weather accounted in the table .

1.Weather Causes. Precipitation will also affect the normal take-off of flights. Mainly reflected in the visual impact， reducing the visibility of the air and the ground. Low-level clouds are also a factor causing flight delays， mainly reflected in the take-off and landing phases， which will pose a threat to flight safety.

2.Airline reasons.Airlines reasons are another important factor causing flight delays， especially for small and medium-sized airlines， whose main problems appear in the management system. The lack of high-level management methods， imperfect management mode and the lack of refined and standardized management spirit will all result in inefficient flight operation and lead to flight delays to a large extent.

3.Reasons for Flight Control .Due to the rapid growth of Chinas air traffic volume and the airspace resources have not yet reached synchronization with it， it is found that the available airspace of Chinas civil aviation is seriously deficient， accounting for only one fifth of total， and is unevenly distributed， especially during peak hours， some air routes are seriously overloaded. And military activities will make the insufficient airspace resources more crowded， thus affecting the normal take-off of the aircraft and aggravating flight delays.

4.Reasons of Passengers. Passengers reasons are also a factor that cannot be ignored in causing flight delays. Some passengers arrive at the airport only after the check-in of the flight. Under normal circumstances， the staff will try their best to help passengers catch the plane， but this has also affected the normal take-off of the flight， and even this humanized service has to some extent fostered the inertia of passengers arriving late.

Ⅲ.The flight delay response measures

1.Improve the Response Measures to Severe Weather. Whether a flight can fly normally or not is inextricably linked to the weather conditions of the entire flight route. Bad weather will not only lead to delays， but also pose a great threat to flight safety. There is great uncertainty and passivity in flight delays caused by weather factors， and flight delays caused by such factors are beyond human control. When there is a long delay， the staff should inform the passengers in time and provide them with rest areas and catering services. If necessary， it should also dredge and isolate passengers in time to avoid the gathering of passengers， especially those who are more emotional， which is of great benefit to avoid disputes.

2.Improving the Operating Efficiency of Airlines.  Flight delays accumulate to a certain extent. Once delayed， subsequent flights may be affected， causing passengers to stay and increasing the possibility of disputes between passengers and staff. Airlines should timely release relevant information on flight delays so that passengers can know the flight situation at any time.

3.Deepen the Reform of Flight Control System. The separation management system of airspace resources management and use rights is increasingly divorced from the current situation. In order to ensure flight safety and stability and reduce waste of airspace resources， relevant departments， based on the principle of high efficiency and safety， rationally divide airspace resources， maximize the utilization rate of airspace resources， and achieve the goal of win-win development for both military and civilian.

4.Emergency Measures to Enhance Passenger Behavior. The most prominent behavior of passengers is late arrival， which is often caused by passengers own. In case of traffic congestion and unreasonable time arrangement， delays will be caused to a certain extent.

Ⅳ.Conclusion

Civil aviation is becoming more and more popular because of its irreplaceable convenience and comfort. However， the problem of flight delay has restricted the development of civil aviation and solving the problem of flight delay has become the general trend. Pursuing high-quality development is the current development trend of civil aviation. This paper analyzes the current situation of China Airlines from four aspects， and gives corresponding solutions， aiming at providing help for effectively easing flight delays.
