what blessings would you say by air? When we send our relatives and friends, we will give them some blessings, such as a safe journey, a pleasant journey, etc. Generally speaking, the most talked about is a smooth journey and so on. But when others are flying, they should never say a smooth journey. Do you know why?
Why can't we have a good flight
When sending friends on a trip, Chinese people usually don't forget to send a sentence of "Bon Voyage". Originally, as for the friends who travel by air, "a good journey" is not a suitable word for delivering the plane. Why do you say that? Let me tell you why.
When taking off and landing, aircraft usually choose to fly against the wind. There are two main reasons: first, it can shorten the take-off and landing run interval; second, it can obtain very good stability and safety. The lift of the wing depends on the relative airspeed between the aircraft and the air, not on the relative ground speed between the aircraft and the ground. In the take-off stage, the ground speed of the aircraft is small. If you want to make the aircraft get enough lift and take off, you need a larger air speed. In the case of a relatively small ground speed, you need to take off in the wind, so that you can achieve a larger air speed to reach the lift and take off. Originally in life, this is the principle when we fly kites. When the wind is against, kites fly high and far.
When the aircraft lands, if it is downwind, the relative speed to the air is small, so the aircraft must increase speed to overcome the influence of wind speed, so as to maintain normal lift. In this way, it is not only necessary to increase the running distance, but also to make it difficult for the aircraft to land accurately, or even to make the aircraft rush out of the runway and then have an accident. However, landing against the wind can avoid this situation and greatly increase the safety.
In addition, when the aircraft takes off and lands, the speed is relatively slow and the stability is poor. If it encounters crosswind, it will tilt the aircraft, so generally speaking, it can land downwind only when it is unable to select the conditions of headwind and the runway length meets.
All the way downwind shows that the wind direction is smooth, and the plane can only fly against the wind. If it is downwind, there is only one exit - falling down. If you wish others a good journey, don't you wish them a bad one? So when a friend goes on a plane trip, you can use a good journey instead of a good one.
There are many prohibitions and taboos like this. For example, when you eat fish with the fishermen and you want to turn it over, you can't turn it over. Then the fishermen will be very angry and even turn their face with you. If you turn it over, they will be very happy. Because turning over = turning over a ship, but it's turning over a river. Banning etiquette is similar to giving an old man a clock during the festival. You will be scolded, or your friends will get married. If you help arrange a yellow sports car, you will be scolded. Because the clock is equal to the end, the yellow sports car is equal to "yellow" run.
How to say the blessing of flying
The blessing words of making an airplane mainly include: a safe journey, a pleasant journey, etc., but never say a smooth journey.
