Aircraft are designed to withstand turbulence, and pilots and cabin crew are trained to deal with it. If a passenger is worried, it is no problem to speak to the cabin crew, who will explain what turbulence is and that it is not something to worry about.

Fortunately, pilots are well trained to deal with even severe turbulence and can usually go out of their way to avoid any major bumps in the sky.
Light turbulence momentarily causes slight changes in altitude and/or attitude or a slight bumpiness. Occupants of the airplane may feel a slight strain against their seat belts. Moderate turbulence is similar to light turbulence but somewhat more intense. There is, however, no loss of control of the airplane.
Sometimes it's unavoidable to fly through light and moderate turbulence, but rest assured your pilots are working to find smooth air. If they encounter severe or extreme turbulence not forecasted, pilots will quickly climb or descend to a safe and smooth altitude.”
The short answer is no, and rest assured that the pilots know how uncomfortable turbulence can make passengers feel. And know that no aircraft has ever crashed because of turbulence. Turbulence has not caused an airplane to crash, Biddle said.
A poll taken on A Fly Guy's Cabin Crew Lounge, the largest network of airline staff on social media, revealed that most airline crew not only like turbulence, but they also enjoy it! That's a comforting thought to think about the next time you're worried when your plane starts shaking. '
From a practical point, no, a modern airliner will not lose a wing due to turbulence. Modern airlines are very tough and designed to withstand extreme turbulence. In theory, it might be possible. But to my knowledge, it has not happened to any jet airliner.
Severe turbulence can cause a plane to drop so suddenly that pilots temporarily lose control. But, again, that's not enough to crash the plane. That's not to say it's never happened. In 1966, human error and turbulence combined to bring a plane down over Mount Fuji.
It's almost unheard of for turbulence to cause a crash, but it can lead to costly repairs for carriers. Usually, the damage is to cabin components like seats and overhead bins when luggage falls out or people hit them.
When an aircraft experiences turbulence, the plane can drop or change altitude suddenly. This is why pilots always caution passengers to buckle up and stay seated when they are experiencing flight turbulence. The sudden movements put passengers at risk.
Usually the pilots will leave the autopilot engaged. In small airplanes with limited autopilots, it is better to fly manually, but with more sophisticated airplanes the autopilot is a valid option in turbulence. Severe turbulence is actually very rare.
Pilots know that flying safely in threatening turbulence requires slowing to VA, the maneuvering speed. This assures that the airplane will stall before its limit load factor can be exceeded. Such a stall is momentary and protects the structure against damaging loads.
Sometimes it's unavoidable to fly through light and moderate turbulence, but rest assured your pilots are working to find smooth air. If they encounter severe or extreme turbulence not forecasted, pilots will quickly climb or descend to a safe and smooth altitude.”
According to the gust envelope, an aircraft by design must be able to withstand a vertical gust of 66 ft/sec when flown at speed Vb (design speed for maximum gust intensity). At or below this speed, the aircraft stalls before it reaches a load factor that could cause structural damage.
Even with turbulence, air travel is still the safest option
First, turbulence has not caused an airplane to crash for over 50 years. So, the chances of you being on the first plane to do so in almost half a century are slim to none.
“The smoothest place to sit is over the wings,” commercial pilot Patrick Smith, host of AskThePilot.com said. These seats are close to the plane's center of lift and gravity. “The roughest spot is usually the far aft. In the rearmost rows, closest to the tail, the knocking and swaying is more pronounced,” Smith added.
All you see is what's outside the window. While it may feel unnerving sitting on a bumpy flight traveling hundreds of miles per hour at thousands of feet in the air, there's no reason to panic or worry. Turbulence is unavoidable. It's experienced on almost every flight to some degree (usually light).
When pilots encounter turbulence, the speed is reduced to turbulence penetration speed Vra. This speed varies from aircraft to aircraft and is provided in the aircraft documentation. The speed for Vra changes with altitude until it changes to a constant Mach number.
Most commercial aircraft now pack weather radar – from the Airbus A321 to the Boeing 777. Weather radar can pick up weather systems sufficiently ahead to warn of precipitation and turbulence, allowing the fast-moving aircraft to divert in time to equally protect the humans and the aircraft.
