F) When the commander and the flight dispatcher have different intentions of dispatching and releasing, the intention with higher safety value should be adopted.

See, and report the decision to the company manager on duty.

However, there are many factors to be considered in the signing and release, and the environment affecting flight operation is also complicated. Mainly think about it.

Several aspects of the content [:

Airport: An airport refers to a specific area on land or water (including buildings, facilities and equipment).

Internal), all or part of it is used for aircraft take-off and landing and ground or water activities. Airports and their airspace pairs

It has a very important relationship with the operation of the aircraft, so for the flight scheduling and release of airlines, it is

Before the release, the runway, taxiway and related navigation and visual AIDS of the airport must be determined.

Don't be seaworthy

Route: A route refers to the scheduled flight of an aircraft from one point (starting point) to another point (ending point) on the earth's surface.

Airline, airline operation includes weather, geographical characteristics and other factors. So be sure to ensure the relevance before signing the flight.

The operating conditions are seaworthy.

Aircraft: An aircraft has wings and one or more engines, and can fly in the atmosphere by its own power.

A plane heavier than air. The influence of aircraft system on flight safety is self-evident. In the civil aviation system, aircraft

It can be divided into Mel /CDL reserved aircraft, aircraft with special restrictions and ordinary aircraft. Master the airworthiness of aircraft.

Identity plays an important role in the safe operation of airlines.

Crew: flight crew refers to pilots, navigators,

Flight operators, etc. The operation manual of S Airlines also defines the technical management regulations of the captain and co-pilot and the aircraft.

The principle of minimum crew configuration and cockpit configuration is established, and the flight crew scheduling workflow is established.

Meteorology: Generally speaking, meteorology refers to clouds, wind, rain, snow, dew, frost, lightning and thunder in the sky.

Isoatmospheric physical phenomena. In aviation meteorology, clouds, visibility, wind direction, wind speed and other shadows

Special weather that affects the safe operation of aircraft, such as lightning, rainstorm, ice and snow, etc.

Line plays a vital role "].

Notices to navigation: refers to the release of information about any aviation facilities, services, procedures or dangers in the form of telecommunications.

The information notice of station, state or change reflects the working conditions of navigation facilities, airport pavement and taxiway.

The working state of airport lighting may affect the operation standard of the airport and the height of the route. Timely acquisition

Getting the latest notice plays a vital role in better ensuring the safety of pilots and sailors.

The main responsibility of the flight dispatcher is to sign and release the flight with the captain and the work quality of the flight dispatcher.

It directly affects the operational safety of airlines. In recent years, although the domestic aviation industry has developed rapidly, it has developed rapidly.

According to the operation manual of S Airlines, every flight of the company is jointly made by the captain and the flight dispatcher.

The approval authority for signing the release, and whether the exercise of this authority can correctly comply with the applicable civil aviation regulations of China.

Chapter and company policies and operating specifications. This authorization contains the following meanings:

A) Confirm the company's pre-flight plan for each flight operation;

B) Before the company conducts each flight operation, verify that the operation must comply with the specified operation rules.

Minimum standards for parts and safe operation;

C) Each flight of the company must be signed by the captain and flight dispatcher.

When using voice communication to express intention, in addition to recording and saving, you must also sign the release form at the initial stage.

Record it on the website. In the absence of flight dispatchers or dispatchers' service agents, dispatchers are used to publish telegrams and voice.

In areas where communication and other applicable methods cannot get in touch with the captain, flight dispatchers can be sent to communicate with the captain at random.

The release of aircraft on the same dispatch or unplanned route is decided by the captain himself;

D) If it is judged by the captain or flight dispatcher that the flight cannot take off or be released as planned.

When the situation is safe or continues to operate, the flight dispatcher shall delay, cancel or re-dispatch the flight.

Appropriate operational control ['].

CCAR- 12 1-R4 Rules for Examination and Approval of Operation Qualification of Large Aircraft Air Transport Carrier +02 1.53 1

It is stipulated whether the captain and flight dispatcher should abide by the China in flight planning, delay, dispatch or release.

Civil aviation laws and regulations and the operating specifications of the holder are all responsible; Monitor the progress of each flight;

Analyze and publish information needed for flight safety.

China's air transportation has developed rapidly, its international status has been significantly improved, its transportation network has been continuously expanded, and its transportation capacity has been greatly improved.

Significantly enhanced, forming an air transport network with Beijing, Shanghai and Guangzhou as the center and combining trunk lines and feeder lines.

In order to meet the demand of air transport market for capacity, domestic civil aviation adopts financial leasing and operating leasing.

Large and medium-sized trunk aircraft have been added, and some regional aircraft have been introduced, which has made the fleet scale grow continuously.

The 12th Five-Year Plan for Civil Aviation Development in China was formally promulgated before. According to the plan, by 20 15

The total turnover of civil aviation transportation will reach 99 billion tons kilometers, the passenger traffic will reach 450 million passengers, and the cargo and mail traffic will reach.

9 million tons, with an average annual increase of 13%, 165, 438+0% and 10% respectively.

American Airlines also mentioned in the plan that by the end of the Twelfth Five-Year Plan, the fleet size will reach 100, of which

/kloc-93 aircraft with 0/00-200 seats and 7 aircraft with 0/00 seats. From the perspective of business scale, the "Twelfth Five-Year Plan"

During this period, S Airlines will realize the transformation from medium-sized airlines to large airlines, and the scale of human resources.

It will also increase with the increase of the fleet, and new systems and new services will continue to expand, and the requirements for the system will be relatively low.

Improve efficiency.

The development history of international civil aviation industry shows that when the scale of airline fleet develops to a certain procedure and organization,

The amount of institutions and information resources has been greatly improved, and it is necessary to effectively integrate and optimize the existing human and information resources.

Especially important.

It is an important task for domestic and foreign airlines to establish an airline operation center.

Companies generally adopt the practice of organizing and implementing scheduled flight operation, and AOC effectively integrates the scheduled flight operation of R Airlines.
