With the development of the Internet, many services have stepped far forward. If earlier, when you were planning to go somewhere, you had to get tickets in advance, but now all this is done much easier. For example, you are flying on vacation. Through the Internet, you can book a hotel room, provide a taxi from the airport to your place of residence, buy a ticket, and all this without leaving your favorite chair.
Moreover, when ordering tickets, you can see in any detail any information of interest to the company and its fleet. Take, for example, a Boeing 737 aircraft. The layout of the cabin, the best places, the location of the wings, kitchens and bathrooms - these issues can be clarified without leaving the computer. Specialized sites can even book your chosen place. Moreover, it’s your choice, which is important, because the plane has both the best seats and standard ones.
Static design
While the model is on assembly lines, it can be improved, modified, changed by some blocks. This happens with all developers in the aircraft industry. At the same time, developments are mainly carried out in terms of updating control systems, flight characteristics, tank volumes and other details that an ordinary passenger will not see. This happened with the Americans - the developers of the Boeing 737. The interior layout, regardless of model modifications, usually does not change its parameters. No company in terms of modifications did not transfer, say, the kitchen in the middle of the cabin. For all machines, the internal layout remains unchanged. With one caveat - unchanged within this model. And if you fly to 737 often, then by changing the company you can get the best (or worst) service. The Boeing 737 cabin will not change - and flying once, you will already know exactly where you were sitting, and whether to choose the same place on the next flight.
Aircraft capacity
Speaking of passenger and cargo capacity, one cannot but note the fact that this aircraft, having first flown in 1967, is still in demand by airlines. For 40 years of production, the aircraft has become more convenient, safer. Nodes, parts were changed, navigation devices were added, and in some rare cases, passenger seats. At the same time, if we depict the number of places with a diagram, there will be peaks on it, there will be drops, but the general direction will grow. So, 737-400 was one of the "giants" in the class. He took on board 168 people and consumed resources, including refueling, much less than classmates (737-300 and 737-500). The following modifications had a lower carrying capacity. This went on until exit 737-800, which took 189 people on board. Like all Boeings, with the exception of version 747, in a Boeing 737 aircraft, the cabin scheme repeats the type of earlier options - 6 seats in a row with one pass between them (3 + 3), which made it possible not to change the width of the hull. With the release of new versions, only the length of the aircraft changes.
737-400 and Transaero
Consider the scheme of the Boeing 737-400 cabin from Transaero. Like many other American production models, the aircraft has three classes: business, economy and tourism. The business class is presented in only 2 rows, but neither the first nor the second row can be called particularly comfortable. People sitting in the first row will have little legroom due to the partition in front. The second row of seats, in addition, has another partition at the back, as a result of which the backs do not recline. The partition is not so dense, so these passengers will hear the noise of neighbors from the house-keeper.
Seats in the following salons already go three in a row. The entire economy class of the aircraft is designed so that the rows of seats can freely move forward or backward, as a result of which rows 14 and 16 do not have portholes. The next 17 (as well as 18) series do not have the ability to fold back because of the emergency exits located behind. At the same time, those sitting in row 18 have slightly more legroom. Those sitting near the porthole in the 19th row may not have one armrest - an emergency exit is located here, while those sitting in the same row in other places do not have these problems.
The tourist class does not need special presentations. Everyone who flew in this class is aware of the small legroom and other “comforts” of flight in this cabin. Mention only those who are sitting in the rear of the cabin. The entire last row is adjacent to the block of bathrooms, so it is quite noisy here, and the backs do not recline. The passenger sitting in the penultimate row at the aisle will also feel.
Top places
Above, we examined the standard layout of one of the most successful Boeing 737 aircraft. The best places on the plane are located in the 10th, first row of the economy class. Passengers sitting by the aisle have the opportunity to recline their backs, and at the same time, due to the narrower than the aisle partitions between business and economy classes, they will get additional legroom. The same partition can cause trouble to neighbors in a row.
Aircraft photo
And to end the conversation, we will provide several photos of the appearance of the Boeing 737 aircraft. Photo of the passenger version - model 737-400, Transaero Airlines, Russia.
For comparison - also the 400th, but the cargo version. If you look closely, the shape of a pair of emergency exits is visible above the wing (737-400 aircraft, Bluebird airline, Iceland.)
Their presence is explained by the fact that this aircraft was not originally planned as a cargo one, but nobody canceled the demand-supply formula, and since all the aircraft were manufactured under a specific order, this one flew out of the American assembly shops in a cargo version.
Conclusion
About the number "13" has already been said a lot. It is all the more surprising that this topic also touched on the developers of the Boeing 737 aircraft. The scheme of the salon has 10 rows, 12 rows, 14 ... But 14 goes right after 12. The salon has seats in the 32nd row, but seats in the 13th row will not be sold to you. This room is simply not there.
