I believe that many children’s shoes who love to sit by the window when flying must have such an experience:
When Qian Airlines opened online check-in, they tried their best in check-in and seat selection. It is to grab a window seat that avoids the wings, away from the toilet, but not too far back, so that you can enjoy the beautiful scenery of the great river and mountains quietly on the plane. As a result, when I got on the plane, I found that the seat looked like this…
Suddenly, the area of psychological shadow suddenly became larger, especially for children’s shoes on long-distance international flights, countless *** flew by in my heart.
So, how can you avoid the side wall seat when you check in by plane? Therefore, today’s content panda is here to discuss this highly technical topic with you. Please take notes~
Some airlines, such as All Sky in Japan, will mark the position of the side wall seat on the seat map.
Some airlines are more thoughtful, such as China Southern Airlines. This year, a black technology called “VR Cabin Roaming” was launched. This function uses 360° panoramic technology, and passengers can watch the panoramic view of the cabin on their mobile phones. Similar to the panorama map function in Baidu Maps, you can see the situation of each seat more intuitively, so that they can easily avoid the side wall seats when choosing seats. At present, China Southern Airlines has enabled this function only on Boeing 777, 787 and Airbus A330.
For the above two situations, you don’t have to worry too much, just follow your heart and choose the seat you want. However, such conscientious airlines are rare after all, and most airlines will not mark the position of the side wall seat on the seat map. How should this situation be handled?
Some children’s shoes will say that after suffering a loss, remember the seat number. True, it’s a workaround, but it doesn’t necessarily work every time. Because even the same aircraft of the same airline has different seat layouts. For example, China Eastern Airlines Boeing 737-800 has four seat layouts.
In fact, it is not too difficult to avoid the side wall seats when checking in, but only if you spend a little time doing your homework.
In the industry, the place on the cabin wall of Youyou.com aircraft without portholes is called “leaking window”. Airline seat maps usually don’t show where the portholes are missing, but they do show where the doors and emergency exits are. Then by comparing the position of the missing porthole relative to the cabin door or escape door, the side wall on the check-in seat map can be determinedThe approximate range of seats within which it is okay to avoid window seats.
Next, let’s take a chestnut to see how this method works.
If you are going to fly tomorrow, now you have to check in, choose your seat, and want to sit by the window. First of all, you have to know what type of plane you will take tomorrow, and it must be accurate to the sub-type.
Determining the model is not difficult. Airline airlines generally inform the aircraft type when selling tickets. Some airlines may not specify the type of aircraft when selling tickets. For example, they only say that the type is Boeing 787, but is it Boeing 787-8? Or 787-9? Or 787-10? Not specified. At this time, you can easily find out the specific model of your flight by entering the flight number in apps like “Flight Manager”, “Travel Horizon”, and “flightradar24”.
For children’s shoes that you don’t even know the model number or are too lazy to check, we suggest that you don’t need to read on. This article is not for you…
After knowing the specific model, in the next few days we will look for pictures of this model on the Internet, and then find out the specific location of the missing porthole. Suppose your plane tomorrow is a Boeing 737-800 of China Eastern Airlines. We can easily find pictures of China Eastern Airlines 737-800 from the Internet. From the pictures, we can also easily find that the 4th and 6th windows in front of the middle emergency exit are not found in the left porthole of 737-800 (as follows Figure), that is, the seat next to the two windows is the side wall seat.
Usually, the distance between the front and back of a row of seats in the economy class is about 1.5 portholes. Therefore, we can calculate that among the window seats on the left side of China Eastern Airlines 737-800, the three or four rows of seats in front of the emergency exit in the middle are side wall seats. To be on the safe side, we can expand the range slightly to include the second to fifth rows of seats in front of the central emergency exit.
Next, go back to the cabin seat layout diagram of the check-in seat selection, and find the second to fifth rows of seats in front of the emergency exit in the middle of the window seat on the left, that is, the seats in rows 35 to 38 must have Two rows are facing the wall, so we only need to avoid these four rows when choosing seats.
If you want to sit on the right side by the window, refer to a similar method. Isn’t it simple? ! Aren’t you surprised? ! No surprises?
So someone has to ask, why are there seats against the wall on the plane?
In fact, wall mounts were not the intent of the aircraft manufacturer or the airline, but rather a design requirement. In fact, almost all mainstream civil aviation airliners now lack portholes.
The reason why there is one less porthole on the bulkhead, It is to make way for the installation of air-conditioning sound pipes.
In order to keep the cabin temperature within a comfortable range, all airliners have complex air conditioning systems. The basic principle is that the air is released from the engine compressor, cooled by the heat exchanger in the belly of the passenger plane, and then sent to the cabin. At this time, the air-conditioning duct arranged between the fuselage frames is needed to transport the cold air from the abdomen to the air-conditioning outlet on the top of the seat. The price paid is the lack of portholes, as shown in the red circle in the figure below.
The photo below was taken before the interior and cabin panels of a Boeing 777 were installed. The yellow one at the top is the air conditioning adjustment duct. The source of cool air delivered by these ducts is located in the belly cabin of the aircraft. Ducts run from the sides of the nacelle to the top of the nacelle. The duct is crushed where it passes through the left and right bulkheads (marked in red circle in the lower right corner). After the interior panels such as the side walls of the cabin are installed, they are flattened. Naturally, portholes cannot be installed in places where air ducts are required to pass through the air.
As airliner size and number of seats increase, the number of empty adjustable ducts also increases, resulting in more and more portholes missing.
