Many passengers have had the following experience: CNC program precision prototype precision rapid metals
A minute or two after the plane took off, there was a sudden “drop”, the thrust of the engine seemed to be suddenly turned off, and the plane seemed to fall!
This feeling lasted only 1 or 2 seconds, and the plane continued to climb upwards again.
At this time, even passengers who have taken many flights will inevitably beat drums in their hearts. What’s with this “fall”? Did the plane engine fail?
In fact, the plane did not fall, and the flight speed and altitude did not decrease at all. The plane just reduces the thrust, and the flight acceleration also decreases. CNC program precision prototype precision rapid metals
Passengers in the cabin are separate individuals from the aircraft. At the moment when the acceleration of the aircraft decreases, the passengers continue to “fly” upward and forward at the original acceleration due to inertia.
At this moment, the plane flies slower and lower relative to the passengers. So passengers will feel the plane “falling” downwards and backwards.
Since reducing the thrust of the aircraft will bring a momentary inertia effect and affect the passenger experience, why reduce the thrust during the climb? CNC program precision prototype precision rapid metals
First, reducing the thrust of the aircraft is to keep the aircraft flying within the low-altitude speed limit.
The aircraft is relatively close to the ground during the climb phase, and if it flies too fast, it will generate excessive noise. There are many low-altitude aircraft and buildings, and the climate environment is more complicated. Flying too fast will also affect safety.
Secondly, reducing the thrust can reduce the loss and fuel consumption of the engine, which can be said to kill two birds with one stone.
Also due to inertia, the passenger’s heart, as an organ that is “suspended” in the body, will respond a little later than the body to changes in acceleration when the thrust of the aircraft decreases. CNC program precision prototype precision rapid metals
Therefore, there will be the illusion of palpitations and panic, thinking that you are nervous.
Choosing a heavy-duty aircraft and a front seat can reduce this “falling feeling”, such as the Boeing 777-300 superjumbo airliner found by Xiaoheng.
Finally, the civil aviation captain uses his salary to guarantee that the height of the plane will not drop during takeoff (it is said that the salary will be deducted if the height is lost)! CNC program precision prototype precision rapid metals
