What is the difference between Airbus 320 and 321

1. The air conditioner of A321 has one more economic flow control knob than 320, which can be placed in low gear when there are few passengers.

2. The rudder and rudder trim deflection angle of the A321 are 5 degrees less than that of the 320.

3. The fuel system of A321 is completely different from that of 3209. The 321 aircraft does not have a ** fuel tank booster pump, only two pilot pumps. Therefore, the fuel supply method of the 321 aircraft is always, **fuel tank-large wing fuel tank-engine, ** fuel tank can not directly supply fuel to the engine, this is to prevent fuel pollution, if two engines use fuel from one tank at the same time, if the fuel is contaminated, then both engines will be in danger, so they should be separated to ensure a safety margin.

The fuel supply of the ** fuel tank of the 320 aircraft is automatically suppressed during take-off thrust, and it is also the independent fuel supply of the large wing fuel tank. In addition, the 321 aircraft does not have external fuel tanks, and the fuel load is less than that of the 320 aircraft.

4. Handling characteristics of A321 aircraft. Due to the long fuselage and large weight, the 321 is not as flexible as the 320, the control stroke is long, and the amount of rod is relatively large when it is flattened on the ground.

Among them, Cebu Pacific, an emerging low-cost carrier from the Philippines, announced an order for 31 Airbus aircraft, including 16 Airbus A330neo, 10 ultra-long-range A321XLR and 5 A320neo aircraft.

However, the purchase of planes is not new, and the novelty is that Cebu Pacific has ordered the A330neo to be ultra-high-density, and these A330-900 aircraft will be able to carry 460 passengers each.

Cebu Pacific A330

Maybe you don't have any idea of the data of 460, and we currently only have A330 CEO for domestic airlines.

Taking Air China as an example, the A330-300, which has the largest passenger capacity, generally adopts a three-class layout (business class + super economy class + economy class), and the passenger capacity fluctuates between 301-311 passengers. The slightly smaller A330-200 has a capacity of only 237-283 passengers when it also adopts a three-cabin layout.

At this time, everyone knows how exaggerated 460 people are. Of course, the number of seats on the plane cannot be compared so roughly, let's take the AirAsia X, which also buys the A330-900 (NEO), to make a comparison.

AirAsia X is the representative of Asia's low-cost carriers and the largest user of the A330neo, with its A330-900 being a two-class layout with a capacity of 377 passengers (12 business + 365 economy), which is also far lower than the 460 passengers of Cebu Pacific A330neo.

AirAsia X A330neo

So why is Cebu Pacific's A330neo aircraft crammed with so many people?

In fact, Cebu Pacific uses a high-density all-economy class layout, but this is not a simple high-density single-cabin layout, because the Airbus A330-900 has a maximum capacity of 440 passengers in a single cabin, and Cebu Airlines needs to have another 20 people.

Passengers who have flown on A330 aircraft in China will know that economy class seats are generally 2-4-2 layout, but on these Cebu Pacific aircraft, economy class seats will be 3-3-3 layout, and the legroom is estimated to be only 30 inches at most.

What would it be like to fly on this plane? Just one word - squeeze.

However, it is not to blame others, Cebu Pacific itself is a low-cost airline, and it is their job to reduce the cost per seat and provide lower fares as much as possible.

The differences between Airbus 321 and Airbus 320 are as follows:

1. The number of people carrying is different. The Airbus 320 is a 150-seater class airliner, with the Airbus 321 having 24% more seats and 40% more space to accommodate up to 220 passengers.

2. The structure of the model is different. The A320 family has the most spacious airframe in the single-aisle aircraft market, and this optimized fuselage section sets a new standard for cabin flexibility. The Airbus 321 has a slightly larger wing area, with two additional emergency exits in the front and rear of the wing.

3. The voyage is different. The Airbus A320 has a range of 5,700 km, while the Airbus A321 has a range of 5,600 km with a full load.

A brief introduction to the specifics of these two aircraft.

The Airbus A320 family of aircraft is a single-aisle, twin-engine, short-haul 150-seat passenger aircraft developed and produced by Airbus in Europe. It is the first commercial aircraft to use a digital fly-by-wire flight control system, and the first civil airliner to relax the static stability design.

Airbus A321 is a twin-engine short- and medium-haul passenger aircraft developed by Airbus Industrie in Europe, and the Airbus A320 extended version. It is the largest aircraft member of the A320 family of aircraft. The Airbus A321 began its construction program on November 24, 1989, and made its maiden flight with a V2530 engine on March 11, 1993.

The differences between Airbus 319 and 320 are as follows:

1. The number of passengers that can be carried on board is differentAirbus 319: 8 seats in first class and 120 seats in economy class, with a total capacity of 128 passengers.

Airbus 320: 8 seats in first class, 150 seats in economy class, a total of 158 passengers.

Second, the range of the flight is differentAirbus 319: Due to the smaller number of passengers carried than the Airbus 320, it has a range of up to 7,200 km.

Airbus 320: Because the number of passengers is more than that of Airbus 319, the range is not as far as that of Airbus 319, with a range of about 5280 kilometers.

Third, the length of the fuselage is differentAirbus 319: It is actually a smaller version of the Airbus 320, and its fuselage is smaller than that of the Airbus 320.

Airbus 320: Its fuselage is longer than that of the Airbus 319.

Fourth, the difference in the maximum take-off weightAirbus 319: maximum take-off weight of 75500kg.

Airbus 320: maximum take-off weight of 77000kg.

Fifth, the difference in empty weightAirbus 319: empty weight 40600kg.

Airbus 320: empty weight 42400kg.

Sixth, the maximum fuel capacity is differentAirbus 319: maximum fuel capacity of 29840 liters.

Airbus 320: The maximum fuel capacity is 29680 liters.

The rudder and rudder trim deflection angles are 5 degrees less than those of the 320;

The fuel system is completely different from the 320. The 321 aircraft does not have a ** fuel tank booster pump, only two pilot pumps.

The fuselage is longer and less flexible than the 320.

The A320 series is a twin-engine short- and medium-range 150-seat passenger aircraft developed by Airbus Industries. There are four types of aircraft, including A318, A319, A320 and A321, which have the same basic cockpit configuration, and pilots can fly the above four different aircraft as long as they receive the same flight training. This common design also reduces the cost of repairs and the availability of spare parts.

A truly innovative aircraft that sets a new standard for single-aisle aircraft, the A320 offers wider seats and more space due to its wider cabin that offers greater comfort to passengers, allowing it to fly farther and faster than its competitors, making it more economical to use. On this basis, larger and smaller models were developed, namely the A321 with 186 seats and the A318 with 124 seats A block.

A321: The first Airbus Industry in Europe to be fully approved.

Commercially financed completed projects. The elongated version, which is a direct derivation of the A320, has 24% more seats and 40% more space than the A320, and two emergency exits in the front and rear of the wing to partially lengthen the wing.

A319: A shortened version derived directly from the A320, with a shorter fuselage than the A320, one less emergency exit on the wing, and the elimination of the bulk cargo compartment in the rear fuselage.

A318: On April 26, 1994, the A319 shortened 100-seater passenger aircraft was officially launched, continuing to maintain the versatility with the A320 series, providing customers with a new choice of 100-seat passenger aircraft.

A380: It is a super-large capacity civil aircraft designed and produced by Airbus in Europe, with a general design layout that can carry 555 passengers. Due to the rational use of new materials such as carbon fiber and new engines and other high technologies, the safety and comfort of the aircraft will be greatly improved compared with existing passenger aircraft.

It's not about which one is better, it's just applicable to different routes and user requirements.

Boeing 747: It is a four-engine (motorized) long-range wide-fuselage transport aircraft produced by Boeing. It is a wide-fuselage airliner that has been successfully developed and sold.

Development began in August 1965, the prototype flew in February 1969, and the first 747 was delivered to Pan American Airways in January 1970 and put into operation, ushering in a new era of wide-body passenger aircraft route service. Its double-decker cabin and unique shape make it the most recognizable subsonic civil airliner.

Boeing 757: The Boeing 757 aircraft is a twin-engine (motorized) narrow-body medium and long-range transport aircraft manufactured by Boeing. In the mid-70s of the 20th century, Boeing decided to develop a new 200-seat model to replace the Boeing 727, based on the Boeing 727, using new wings and advanced engines to reduce the cost of use by reducing fuel consumption and reducing the weight of the airframe.

First, Airbus A321 and A320 also use full fly-by-wire operation, but the models are different, which is very good.

Second, the B-747 series of long-range, wide-body, jumbo airliners introduced by Boeing in the 1970s, while the B-757 is a purely long-range airliner, with no good or bad except for the size of the airframe, depending on the actual destination of the flight - and the Boeing Airframe performance is quite good. The Airbus A380 is much larger than the B-747 (the length of the upper cabin is the full length of the fuselage), however.

Relatively speaking, due to the unreasonable overall layout of the airframe (even Airbus engineers have tried their best...) There are a lot of inconveniences for airlines to actually operate it – and the A380 is only available at a few airports around the world, so the B-747 is relatively better

Personally, I think that it is better to use A320 and A321 or B737 for short-haul flights, and it is better to use A330, B767 and other aircraft for short-haul flights.

It is better to use A340, B777, B747 for long distance.

The A380 is a new type of passenger aircraft, which is considered to be in the application stage, so the A380 is not recommended for the time being.

Airbus A320 is a single-aisle, twin-engine, short-range 150-seat passenger aircraft of European Airbus, and is the world's first commercial aircraft to use a digital fly-by-wire flight control system, breaking Boeing's monopoly position in the civil aircraft market. The A320 is currently the world's second-most produced jetliner after the Boeing 737.

Compared with the A320, the A321 is an extended version developed by Airbus on the basis of the A320, and it is the largest aircraft in the A320 family. Compared to the A320, there are 24% more seats and 40% more space, the wing is enlarged, and CFM56 and V2500 engines are used. It can accommodate up to 220 passengers.

The A321-200 has increased fuel tank capacity to also carry 186 passengers, increasing the cruising range to 3,000 nautical miles (5,500 km). The A321-200 uses 2 CFM56-5 or IAE V2500.

In general, the 321 is a little better and has an advantage in short and medium-haul routes;

1. Airbus A320 is a short- and medium-range single-aisle passenger aircraft, which is generally used to fly medium- and short-range domestic routes or short-haul international routes; The Airbus A330 is a medium- and long-range dual-aisle wide-body airliner, which is generally used to fly medium- and long-distance international routes.

2. A320 is a single aisle, that is, an aisle, with a cabin width of only meters, while A330 is two aisles, the cabin width reaches meters, and the flight distance is much farther than A320.

3. The maximum range of the A330 can reach 12,500 kilometers (A330-200 type), while the maximum range of the A320 is only 6,800 kilometers (A319-100).

4. In terms of passenger capacity, the A330 can carry up to 338 passengers (A330-300), while the A320 can carry up to 185 passengers (A321-100).
