It is a common flight phenomenon for airplanes to encounter airflows in the air, especially when flying in the troposphere. The following is a detailed description and suggestions for airflow bumps:

---

1. Types of airflow bumps

· Clear sky bumps: turbulence occurs when there is no clouds at high altitude, and it is difficult to detect it in advance through radar.

· Thermal bumps: caused by uneven heat on the surface (such as summer afternoon), which is common at low air.

· Terrain bumps: caused by airflows passing through mountains or buildings.

· Rapid bumps: caused by wind shear on the edge of high-altitude rapids.

· Bumps in the clouds: The airflow is strong near the rain clouds and thunderstorm clouds, and the pilot usually takes the initiative to fly around.

2. Impact on flight safety

· Modern passenger aircraft are designed with high strength and can withstand the stress of far exceeding normal bumps.

· The main risk is that passengers and crew may be injured when they are not on seat belts (accounting for more than 90% of airflow-related accidents).

· Pilots will adjust the route in advance through meteorological radar, air control notifications and crew reports.

3. What should passengers do?

· Fasten your seat belt throughout the whole process: Even if the indicator light is off, there may be no warning of sudden bumps.

· Stay calm: bumps are usually just temporary discomfort and do not mean danger.

· Obedience to the crew's instructions: stop using the bathroom, sit firmly and put away loose items.

· Avoid panic: The plane will not crash due to bumps, and the shaking of the fuselage is a normal manifestation of structural elasticity.

4. Pilot's countermeasures

· Adjust the flight altitude or route to avoid strong bumpy areas.

· Inform the cabin before entering the bump, and control the speed to reduce the impact.

· In case of sudden serious bumps, follow the standard procedures to ensure the stability of the flight.

5. Important reminder

· Bump ≠ Danger: Similar to a car driving on a bumpy road, it is a normal physical phenomenon.

· Weather forecast and technical guarantee: Route planning will refer to real-time meteorological data, and airborne radar can detect the weather ahead.

· Low probability of serious bumps: only about 0.1% of flights will encounter strong bumps, and the risk of serious injury is extremely low (about 1 case per 1 billion passenger miles).

Psychological advice for passengers

· Understanding knowledge helps to reduce anxiety: bumps are the result of airflow movement, not mechanical failures.

· Observe the crew: their calm attitude often shows that the situation is normal.

· If you need help, you can press the call button to communicate with the flight attendant.

Encountering airflow in flight is a common part of air travel, and the modern aviation safety system has incorporated it into normal management. As long as you follow the safety guidelines, flying is still one of the most efficient and safe means of transportation.
