Why Is The Seat Recline Angle Of The Airplane And The High-speed Rail Not Modified?

The train does not know much. From the experience of the ride, in fact, the seat spacing of the CRH EMU is large enough. The front tilting back actually has little effect on the comfort of the rear ride. The main problem lies in the design of the small table. The small table design fixed in the front seat makes the space on the small table greatly affected when the front backrest is tilted. It is also common to get the water cup to touch things. It would be much better if the small table could be designed to move back and forth like an airplane, or to get it into the armrest. As for the aircraft, the seat reclining angle is small and the passenger feels uncomfortable. The angle is large and affects the passengers behind. The seat shell is fixed in the old economy class of Cathay. The seat cushion is slippery, the backrest slides down, and the leg is affected. Space and comfort...The space of the aircraft is very limited, and the airline has to maximize the benefits. How to place more seats in a limited space is the first priority, and the business space with more space exists. Such as the problem of not being able to pass straight through the road or the narrow leg space, not to mention the economy class. Passengers are more concerned about cheaper fares, larger PTV screens, or air wifi. In contrast, the backrest problem will not be so careless. After all, they are in economy class and have to ride bicycles. Therefore, for the aircraft, the seat reclining angle is not an industrial design problem, but a commercial interest problem, to do the biggest thing with the least cost, sacrifice the unimportant experience, and put the interests in a more obvious place. The result of airlines constantly compressing economy space is that you can't find a perfect solution, or you can spend more on two cabins...
