Info about Aircraft registration number, flight number and nationality code (all)

2022-01-14

At present, the flight numbers of domestic routes are composed of two English letters and four Arabic numerals.
Two of the letters are short for each airline.
For example: CA stands for "Air China", CZ stands for "China Southern Airlines", MU stands for "China Eastern Airlines", 3U stands for "Sichuan Airlines", FM stands for "Shanghai Airlines", HU stands for "Hainan Airlines", MF stands for "Xiamen Airlines", ZH represents "Shenzhen Airlines", SC stands for "Shandong Airlines".
Four Arabic digits:
the first is the code of the regional administration of the aircraft departure, such as Beijing Bureau "1".
The second is the code of the administration of the region to which the aircraft will fly, such as: the South Central (Guangzhou) Bureau is "3", the other several bureaus are: Xi 'an Bureau "2", Chengdu Bureau "4", Shanghai Bureau (Eastern Airlines) "5", Northeast (Shenyang) Bureau "6", Taiyuan Bureau "7", Xiamen Bureau "8", Xinjiang Bureau "9".
The third and fourth digits indicate the flight number, which is the specific number of the flight. If the fourth digit is odd, it means that the flight is a outbound flight; if it is even, it is a return flight. For example, CA1201 represents the outbound flight from Beijing to Xi 'an operated by Air China.

1. Each aircraft has a unique registration number (just like our ID number), consisting of one letter and four digits.
The letter is the nationality of the aircraft, the Chinese aircraft is represented by the letter B, so, no matter you see in any airport in the world on the fuselage of the aircraft with a B number, this aircraft must belong to China.
2. The last four digits show the type of aircraft. The earliest arrangement method of civil aviation in China is: B20XX is B777,B21XX is MD80/82,B22XX is MD90,B23XX is A300,B24XX is B707/747,B25XX is B737,B255X is B767,B26XX is TU154,B27XX is BAE 146 and YK42,B28XX is B757,B345X is Y7, and B34XX is AN24.
Now with the retirement of old aircraft and the introduction of new aircraft, there has been a lot of change.
3. The aircraft numbers do not start with B1,B3 is a regional small aircraft,B4 is a military aircraft number, and B7 is a helicopter. Therefore, when the number of civil aircraft is full of B2, the row numbers of B5 and B6 will be used. There is no distinction between Airbus and Boeing, and there is no distinction between models, after the B50 is full, it begins to row B60, and it has not yet been seen that the APU of the civil aircraft numbered B51-B59 or B61-B69 means Asist Power Unit(auxiliary power unit), and his essence is a centrifugal turbine engine and related generator equipment. The role of the APU is to provide electricity and compressed air to the aircraft independently, and a small number of APU can provide additional thrust to the aircraft.
Before the aircraft takes off on the ground, it is powered by the APU to start the main engine, so it is not necessary to rely on the ground electricity and air source vehicle to start the aircraft.
When on the ground, the APU provides power and compressed air, ensures lighting and air conditioning in the cabin and cockpit, and uses all engine power for ground acceleration and climb during takeoff, improving takeoff performance.
After landing, the APU still supplies electricity, lighting and air conditioning, allowing the main engine to shut down early, thus saving fuel and reducing airport noise.
The auxiliary power unit is usually turned off after the aircraft has climbed to a certain altitude (below 5,000 meters). However, when the main engine stops in the air during flight, the APU can be started in the high air below a certain altitude (generally 10,000 meters) in time to provide power for the engine restart.

For large aircraft, this device is mounted in the tail cone, and the An-124 has two APUs! On the modern large and medium-sized passenger aircraft, APU is the main equipment to ensure that the engine stops in the air and then starts, which directly affects the flight safety.APU is also a necessary condition to ensure that the cabin is comfortable when the aircraft is parked on the ground, which will affect the choice of passengers.Therefore, APU becomes an important and indispensable system in the aircraft.
Some fighters like Su-27 and F/A-18 also have APU!
