There are rumors that the stop chims are found not only in trains, but also in airplanes. We checked whether this is so.

There is a well-known puzzle with a catch: what color of the stop-wheel in the plane? Evgeny Sidorenko in his book “Logic. Paradoxes. Possible worlds: Reflections on thinking in nine essays " Writes: “Paradoxical, but to the question:" What color is a stop-movie on an airplane? " Most of the asked, after thinking, almost always give an answer. Some say that blue, others - that red, others admit that they do not know. When they later realize the absurdity of the issue, they laugh in surprise and without resentment. This is a typical example of the issue in which the asked person is distracted by the absurdity of this very question. ”

But is it so ridiculous? Of course, the very idea that passengers can stop the engine in the air, jerking over the lever, it seems crazy. However, it is important to know not only the word “stop-movie”, but also the concept that is hidden behind it. As they write, in particular, "Arguments and facts", On the aircraft, there is still a stop crank, it is only useless to look for him in a passenger salon. The stop crank is on the dashboard in the cabin of pilots, where access to passengers is prohibited. Yes, and its function in the plane is not at all emergency braking, like the stop chines in trains. On board the aircraft, this device serves to open and close the supply of fuel to the engines. Stop cranes are transferred to the same position before starting the engines so that the fuel supply goes, and in the opposite-at the end of the flight, when the fuel needs to be blocked.

However, there is a nuance. The same “arguments and facts”, referring to the words of an experienced pilot, notice that this device cannot be called a stop crane. According to the pilot, its correct name is the fuel crane, and the popular nickname is not used by the pilots themselves and even technically incorrectly. Firstly, this professional opinion contradicts the large number of photographs found on the network. The inscription "Stop-Kin" on the lever (sometimes on the toggle switch) or near it is clearly distinguishable.

Despite the antique type of dashboard presented, among them there are also quite modern aircraft. For example, in the upper left corner-a fragment of the dashboard of the An-124 Ruslan aircraft, one of the largest aircraft in our time. So at least at the level of on -board terminology, such a name is correct.

Well, the corresponding literature will help us find out the official (technical) name of the device. In the training manual of 2015 "Systems of on -board equipment of aircraft and helicopters»The term" fluid crane "was used, in the GOST operating in Russia"Fuel systems and helicopters" -" Fuel Fuel Crane "(in English - Shutoff Valve). But in AN-24 aircraft flight management guide It is said exactly about the stop chill (as well as about the STOP-Crane switch). As for helicopters, in MI-8 documentation This device is called a stop crane. As you can see, in all cases the terminology is different, but it should be noted that there are no cranes directly on the aircraft dashboard - there are levers (toggle switches, switches, switches), and the taps themselves are much deeper, inside the fuel system.

So, we were convinced that the term “stop-krane”, although absent in the GOST, is found on the dashboard and in the operating manuals of aircraft. Therefore, using it, especially in everyday life, is quite correct. As for the color of the stop crane, as can be seen in the photographs, it can be almost anything.
