Do Airbus A320 and Boeing 736 have stabilizer trim ?

All civil jets move the entire stabilizer to pitch trim, because the aircraft is too large for the pilot to handle by hand, so hydraulic control is added. You may think that trim is achieved by directly adjusting the elevator back to the center position, but in fact, because the weight of the aircraft, the center of gravity changes greatly with the load and fuel use, which will cause the elevator to deflect too much relative to the stabilizer and increase the resistance, so it is directly used to deflect the stabilizer method for balancing, but it is different from the traditional full-motion flat tail, because the stabilizer is very heavy and the activity is slow, so the direct control still depends on the elevator.

The 320 is fly-wire, and there is no need for manual trim after takeoff, and if the 737 is in manual mode, the trim is controlled by the electric gate at the thumb position of the steering wheel (for convenience), and the trim is automatically coordinated during automatic driving, and the 737 aileron and rudder are trimmed by changing the back to the center position, and the 320 is fine, and there is almost no need for trim.

For the sake of me, I'm very good and hard-working.

736 Yes! Modern large and medium-sized civil airliners due to the large longitudinal size, the longitudinal displacement of the center of gravity is up, if the center of gravity is forward or backward, the amount of longitudinal maneuvering required is very large, relying on the elevator alone can not fully realize the longitudinal control, therefore, the water level of most aircraft can be adjusted according to the angle of the corner. Before take-off, the aircraft should be leveled according to the load and balance of the aircraft.

320 too.

Airbus is more technologically advanced than Boeing and more advanced than the 320 and 736. Trim is a "waltz", there are three steps, not to mention ......Due to factors such as wind direction and weight on board, the original center of the aircraft may change during the flight, and yaw will occur, and trim is required. There is 736, and 320 electronic technology is high, and it seems to be an automatic correction.

Every plane should have.

If you want to be comfortable, you need the Airbus 320, and if you want to be economical, you need the Boeing 737.

On the face of it, it is difficult to find any significant differences between the two aircraft. They are all standard short- and medium-range aircraft. Their cabins are arranged in 3-3 and sometimes equipped with business class products that are appropriate for their range capacity.

There are overhead compartments for carry-on luggage, a single aisle that separates the seats, and there are usually lavatories at the front and rear of the cabin.

However, there are some distinct differences in passenger comfort and experience. The cabin of the Airbus A320 is wider than that of the Boeing 737. Seven inches doesn't seem like a big deal.

At the same time, when you consider that the Delta Air Lines Airbus A320 has an economy class seat width of 18 inches, compared to inches on the 737 of the same airline, you see that it has a very big impact on comfort. Even on short-haul flights, slightly wider seats are always welcome.

Due to the wider cabin, the Airbus also has less curvature. It's just a slight difference, but when you're trying to rest your head on the window seat, it means more room to maneuver on the A320.

The difference between the cabin windows was also noted. The Boeing 737 has slightly larger windows than the A320, which one would immediately consider as a positive. However, they are located lower in the fuselage.

This means that taller people may find themselves bending over to properly see out the window. At the same time, the windows of the A320 are positioned slightly higher to be at eye level with most passengers.

First, the design features are different.

1. Airbus A320: The Airbus A320 series uses a large number of composite materials as the main structural materials. The main system consists of two parts, one of which works and the other part operates through the monitoring of data provided by various parties.

Two other computers are responsible for carrying out flight plans, and four are monitoring the engines and other systems on board.

2. Boeing 737: The wing of Boeing 737 adopts cantilever medium wing, and the engine nacelle is installed at 35% and a half wingspan. Large wing load (500 kgm2) and a small sweep angle.

aspect ratio, 1 4 chord sweep angle 25 °, average relative thickness. The inside of the engine nacelle is a Kruger leading edge flap and the outer side is a three-stage leading edge slat.

Second, the model. 1. Airbus A320: The main models are A320-100, A320-200, Airbus A321, Airbus A319, Airbus A318, and Airbus A320neo.

2. Boeing 737: The main models are Boeing 737-100, Boeing 737-200, Boeing 737-300, Boeing 737-400, Boeing 737-500, Boeing 737-600, Boeing 737-700, Boeing 737-800, Boeing 737-900, Boeing 737MAX

Third, the manufacturer is different.

1. Airbus A320: produced by Airbus Europe.

2. Boeing 737: produced by Boeing in the United States.

Airbus A320 (Airbus A320) is a short- and medium-range narrow-body commercial airliner manufactured by the French company Airbus, with member families including A318, A319, A320, A321 and business jet ACJ.

The largest model of the A320 family, the A321, entered service in early 1994 and has a range of 5,600 km and 3,000 nautical miles. With a capacity of 185 passengers in a typical two-class cabin layout (up to 220 passengers on charter or low-cost operations), its extremely low seat operating costs are unmatched.

At the end of February 2012, 13 Continental Airlines and 3 business jet companies operated 675 A320 family aircraft.

The Boeing 737 is a short- and medium-range, twin-engine narrow-body jet airliner, originally a derivative of the Boeing 707 and Boeing 727, and is a short-range civil aircraft with low operating costs, and has developed nine models so far. The Boeing 737 is the only narrow-body aircraft currently in production at Boeing, including the -600, -700, -800 and -900ER.

The Boeing 737 aircraft is the workhorse of Chinese airlines.

In 2011, Boeing announced its 737 MAX program, in which Boeing will offer three new models, the -8 and 737-9, to replace the -800 and 737-900ER, respectively. The main changes are the use of the CFM International LEAP-1B engine, the addition of fly-by-wire technology to the spoiler, and the extended nose landing gear, which is expected to be delivered in 2017 [74][75]. On December 13, 2011, Southwest announced that it would order 150 737 MAX as launch customers.

I understand it, what help do I need?

Compared with the Boeing 737, the Airbus A320 has long legs and the other has short legs.

The Airbus A320 family and the Boeing 737 family each have different generations of products, so it is impossible to make a very general comparison. With the retirement of the second-generation 737 model on the domestic passenger line, the current mainstream 737NG is basically in service, which is basically the same level as the A320 series models in terms of passenger capacity, cabin layout and other aspects that directly affect the riding experience.

The new generation of A320neo and Boeing 737MAX belong to their own new generation products, both of which have been improved to varying degrees, but the horizontal comparison is still generally at the same level.

From the passenger's point of view, there is not much difference, both are narrow-body aircraft, single-aisle, 2-2 for first class and 3-3 for economy class. The distance between the front and back may vary slightly from airline to airline, but it is basically not comfortable. Basically, it is a short- to medium-range model.

Airbus A320 and Boeing 737 can be distinguished by small differences in fuselage appearance:

Airbus A320 and Boeing 737 are produced by Boeing in the United States, produced by Airbus in France, 737 has been developed since 1969, 320 has been developed since 1988, and more advanced technology is applied, and the wingtip winglets are different, A320 is gull-shaped, 737 is pointed, and 737 and 320 have their own marks on the fuselage.

Distinguish between the tags and ** as follows:

The 737 has pointed winglets.

The A320 has gull-style wingtip winglets:

In addition, you can look at the porthole, as shown below, the top is an Airbus A320;

Underneath is the Boeing 737, and the porthole of the Boeing 737 has a downward notch-like sign.

The A320 has winglets up and down and the 737 has no winglets or only upwards.

There are also later versions of the 737 with a flatter engine bottom.

There is a model number written on the tail of the airplane.

I am a civil aviation worker.

The 737 series is available in two variants.

The old aircraft was called the 737 classic

There are three sizes: -300 or -400 or -500.

It is an old model and has been discontinued.

Most do not come with first class.

For example, Shandong Airlines' 737-300

The registration number is B-2877

**The 737 is called NG aircraft.

There are -600 or -700 or -800

It belongs to the first model in production.

Most of them choose to reserve first class.

For example, Shandong Airlines' 737-800 model.

The registration number is B-5065

Airbus A320 belongs to one of the most advanced medium-sized aircraft in modern times, its whole operation uses a large number of electric drives, most of them choose to retain the first class, such as the A-320 of China Eastern Airlines, and some airlines in order to cancel the first class to fight for the market with economic fares, such as Spring Airlines, aircraft manufacturers can arrange the layout according to the needs of customers, whether to retain the first class, can be changed, as for the route you said, Wuxi to Chongqing.

It's hard to say if there is first class or not.

This is because there are many airlines with many aircraft types that carry out this flight.

That is to say, the aircraft of Shenzhen Airlines that performs the route at 8 o'clock every day may be different, that is to say, today it is B-5065, tomorrow it may be B-2877, and different airlines will have more aircraft to carry out the route at that time.
