In fact, this question cannot be complete, first, the classification of aircraft.
An airplane is a carrier of the air transport system. After almost a century of development, the flight performance of the aircraft has reached a very high level. Taking speed as an example, although most of the current civil aircraft are subsonic (that is, the ratio of aircraft flight speed to sound speed or Mach number m is smaller than that of civil aircraft), but transonic (m is between to) and supersonic (m is between to) civil aircraft have also been put into operation, such as the Tu-144 aircraft put into operation in the former Soviet Union in 1977, and the British and French cooperative development and put into regular route operation in 1976"Concorde"aircraft, etc.
All vehicles can be divided into aircraft and spacecraft, the former is an atmospheric vehicle, while the latter is a space vehicle (such as rockets, space shuttles, planetary probes, etc.). Aircraft can be divided into lighter-than-air aircraft (such as balloons, airships, etc.) and heavier-than-air aircraft, such as airplanes and various aircraft, gliders, gyroplanes, etc. Airplanes are the most important aircraft, and because of its many uses, there are many ways to classify it.
1) Classification by structure.
Aircraft can be classified into different types according to different configurations.
According to the number of wings, aircraft can generally be divided into biplanes and monoplanes.
According to the engine type, it can be divided into piston engine and propeller group aircraft and jet aircraft.
According to the number of engines, it can be divided into single-engine aircraft, twin-engine aircraft, three-engine aircraft and four-engine aircraft.
According to the take-off and landing location, it can be divided into land aircraft, snow (ice) aircraft, seaplanes, amphibious aircraft and carrier-based aircraft.
According to the take-off and landing mode, it can be divided into a sliding take-off and landing aircraft and a vertical short take-off and landing aircraft.
In addition, it can be classified by the position or number of tails and the number of fuselages.
2) Classification by use.
Since the performance, construction and shape of an aircraft are largely determined by its use, classification by use is one of the most important classification methods. Modern aircraft can be divided into two categories: military aircraft and civil aircraft according to their uses, and there is another type of aircraft specially used for scientific research and testing, which can be called research aircraft. The following is mainly about civil aircraft.
Passenger aircraft are used to carry passengers and mail, to connect cities and regions in China, or to cities in the world. Passenger aircraft can be further divided into according to size and range:
long-range (large) passenger aircraft used on intercontinental routes; medium-haul (medium-sized) passenger aircraft used on domestic trunk lines; Short-haul (light) passenger aircraft used on local routes (feeder routes). At present, most of the passenger aircraft used by various countries are subsonic aircraft. There are two types of supersonic passenger aircraft, which have a maximum cruise speed of about twice the speed of sound.
Medium-sized passenger aircraft are widely used, both jet and propeller, such as:"Trident"。
Cargo planes are used to transport goods, generally with a large load, a large hatch, or the fuselage can be turned to facilitate loading and unloading of goods; Freighters are easy to repair and maintain, and can fly in complex climates. So can't give you a detailed answer.

The main wing of the aircraft is the main equipment responsible for providing upward force to the aircraft, its size is proportional to the size of the aircraft, this scale value is a range, I forgot how much! But the biggest ones seem to be B2 and B52! It's 50 meters long!
-
Different aircraft types of the same airline have different wing positions, and different airlines have different numbers of the same row.
For example, the wing of China Southern Airlines Passenger 320 is located in rows 6-12, and the engine of the aircraft is located at the wing, so the noise near the wing is large. Considering the flow of passengers, the closer you get to the tail and the sides of the fuselage, it will be relatively quiet. The louder the noise gets closer to the lavatory, galley, cabin doors and aisles.
Tips for choosing seats on the plane.
1. Choose both ends of the seats with a good position to see the scenery.
If you want to see the scenery outside from the plane, choose a window seat. The seats are arranged in the horizontal row according to A, B, C, D, E, and F, that is, if the plane seats are six in the horizontal row, they are A, B, C, D, E, F, and the window seats are A and F. However, there are many horizontal seats, and the seats at both ends are by the window.
2. Choose the middle of the position that is convenient for entry and exit.
Some passengers need to leave their seats frequently to go to the toilet, so in order to choose seats on both sides of the national highway for convenience, it is best to choose C and D as shown in the example above.
3. Passengers who need to rest choose to stay by the window.
If you need to rest, you need to avoid being disturbed, and the window position will not be disturbed too much by passengers, and you can also sleep by the window.

In Economy Class, you can also stay elegant and comfortable with seat selection. Seat selection is important, and the one that suits you is the best.
1.Choose between front or back.
The front seats are relatively less turbulent and noisy, and in this respect, the front seats are relatively more comfortable than the back seats.
But we can't admit death, generally there are more people in the front of the cabin, but when the flight is not full, there are relatively few passengers in the back row, and if you are lucky, you may be able to sleep in the back seat
2.Avoid seats that cannot be adjusted in terms of seat width.
Seats in the last row of the aircraft and in the front row of the emergency exit row cannot be adjusted. If you choose this kind of seat, it can only be used as training to correct the hunchback.
4.Machine wings? It's too noisy!
Try to avoid seats near the wings, as these seats are usually noisy, so passengers who do not have their own earplugs are advised to choose carefully
5.The emergency exit is wide, but "picky".
There is plenty of room in the emergency exit seats, but it's not like you can sit if you want to. Emergency exit seats are mainly for emergency evacuation, leaving plenty of legroom. However, according to the regulations of the airline, this row of seats will generally be arranged for those who are able-bodied, and the elderly, weak, sick, disabled, pregnant and young, foreigners with language barriers, drunk and overly obese people will not be placed in this position, so they usually need to go to the counter to select a seat.
If you want to have less bumps, choose a place close to the center of gravity of the aircraft, generally near the middle of the wing (the bump up and down is relatively small), and the corridor (the left and right shaking is relatively small), but this place is generally near the installation site of the wing suspension engine, and the noise is slightly louder
Choose the seat in the back and pull over instead of the window (if you don't know how to go to the toilet on the plane, choose the window), pull over to the toilet, and have easy access to your luggage.
Biggest advantages!! That is, there is a good chance of getting a row on you.

The large wing of the aircraft of the 737 320 series should be in the 36-40 row. Other aircraft are not easy to determine, depending on the specific model, the online check-in page should also be visible.

The wings of an airplane are called wings.
Wings mainly refer to the wings of flying animals, but airplanes are flying instruments made by humans, and the role of the wings of the airplane is different from the role of the wings of the flying movement.
The wing is one of the important parts of the aircraft and is mounted on the fuselage. Its main function is to generate lift, which together with the rear wing forms good stability and maneuverability. In addition, ammunition, equipment and fuel tanks can be loaded inside the wing, and landing gear, engines, suspended missiles, auxiliary fuel tanks and other external equipment can be installed on the wing.
The name of each part of the aircraft
1. Wings. Wings – The main function is to generate lift to support the aircraft in the air, but also to play a certain role in stability and operation.
Ailerons and flaps are generally installed on the wings, and the ailerons can be manipulated to make the aircraft roll, and the lift can be increased by lowering the flaps. Engines, landing gear and fuel tanks can also be installed on the wings.
2. Fuselage. Fuselage - the main function is to carry passengers, passengers, cargo, and various equipment, and connect other parts of the aircraft such as wings, tail and engines into a whole.
3. a rear wing. Tail – includes both horizontal and vertical tails. The horizontal tail is composed of a fixed water stabilizer and a movable elevator, and some high-speed aircraft combine the horizontal stabilizer and the elevator into a full-motion flat tail. The vertical tail includes a fixed vertical stabilizer and movable rudders.
The function of the tail is to control the pitch and deflection of the aircraft to ensure that the aircraft can fly smoothly.
4. a landing gear.
Landing gear - The landing gear of an aircraft is mostly composed of shock absorber struts and wheels, which are used to support the aircraft during take-off, landing and taxiing, ground taxiing and parking.
5. a power unit.
Powerplant – The powerplant is mainly used to generate pull and thrust to move the aircraft forward. Secondly, it can also provide electricity for other electrical equipment on the aircraft.

Summary. Hello friends, the wings of the plane are normal, they are between 35 and 45, and the wings can be seen here.
Regardless of the size of the aircraft, it is almost always in this position, because it is designed according to the overall structure, and it is impossible to appear in other positions, which is the position that is most conducive to the overall flow of the aircraft.
In what row are the airplane wings?
Hello friends, the wings of the plane are normal, they are between 35 and 45, and the wings can be seen here. Regardless of the size of the aircraft, it is almost always in this position, because it is designed according to the overall structure, and it is impossible to appear in other positions, which is the position that is most conducive to the overall flow of the aircraft.
Anyone? Can you?
Hello friend, just got your message. It's basically a position like 40, and you can't go wrong.
Is there a choice for 51?
Hello friends, there is no problem with seat 51, there will be no particularly loud noise here, if you choose normally, 45 to 55 can be. It's not like people say, it's very noisy.
Can children choose.
Yes pro. There is no problem for children to choose here, and there will be no bumpy feeling, it is still very smooth.

Airplane winged means that the player plays a hand of two or more consecutive three cards, and must carry an equal number of cards or pairs after playing.
1. The value of the three cards must be consecutive.
2. The number of three cards must be two or more.
3, the cards must be the same card type, if you choose a single must be all single, if you choose a pair must be all pairs.
4. The number of cards brought must be consistent with the number of three cards.
Pressed hand
1, when comparing the airplane with wings card type, first of all, the two players played the same card type, the front player is single, the player who came out of the back must also bring a single, the player who played in front of him is a pair, and the player who came out of the back must also bring a pair, under the premise of the same card type, compare the card with the maximum number of points in the three cards, the greater the number of points, the greater the card power value.
2. In addition to the wings of the aircraft itself can press each other, players can also choose rockets or bombs to press this card type.
The transmission rate of the virus on the plane is still quite high, after all, the crowd is relatively dense, and if passengers sit down with protective measures, the probability of being infected will be greatly reduced, such as wearing masks, washing hands frequently, and trying not to touch other people's belongings.

There are generally steel, aviation aluminum alloys, composite materials, and some powerful titanium alloys, carbon fibers, etc. The engine, the less the higher the efficiency, the current engine, the general aircraft 2 engines are already very safe, when a failure of the aircraft can still fly, this has a reliable theory as a guarantee, so don't worry, not 4 rounds must be higher than 2 rounds of safety factor, this has more to do with the engine itself. The problem with the wing, the safety is better, and the inspection of civil airliners is very strict. >>>More
