If a plane is flying along at a constant speed and height, then suddenly the headwind reduces, or it enters a descending column of air, this can cause the aircraft to suddenly descend, Gratton explained.

Eleanor Barker answers your travel questions.We humans are much more sensitive to the rate of change, how fast you are going up or down, than the depth of the dip. Turbulence can very rarely cause a change of up to 100 metres, but it is almost always less than 30m.
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.
Turbulence is a sudden and sometimes violent shift in airflow. Those irregular motions in the atmosphere create air currents that can cause passengers on an airplane to experience annoying bumps during a flight, or it can be severe enough to throw an airplane out of control. (The pilots) aren't scared at all.
Should you be scared of turbulence? 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.
While pilots can't actually see turbulence, they often know what is coming up, thanks to reports from other planes, weather reports, and radar equipment. However, clear air turbulence (severe turbulence occurring in cloudless areas) can sometimes catch pilots off guard.
At times like this, pilots will slow to a designated “turbulence penetration speed” to ensure high-speed buffet protection (don't ask) and prevent damage to the airframe. We can also request higher or lower altitudes, or ask for a revised routing.
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. '
Severe turbulence causes large and abrupt changes in altitude and/or attitude and, usually, large variations in indicated airspeed. The airplane may momentarily be out of control. Occupants of the airplane will be forced violently against their seat belts.
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.
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.
Winter has strong winds and blizzards, and summer's hot heat can create unstable air, thunderstorms, and tropical storms. That means flying during the holidays often means more turbulence than other times of the year. So if possible, avoid flying between December and February or June and August for a smoother flight.
The middle seat in the final seat is your safest bet
The middle rear seats of an aircraft had the lowest fatality rate: 28%, compared to 44% for the middle aisle seats, according to a TIME investigation that examined 35 years' worth of aircraft accident data.
With this in mind, horizontal winds (also known as “crosswinds”) in excess of 30-35 kts (about 34-40 mph) are generally prohibitive of take-off and landing. As far as how this happens, it depends on where you are in flight.
It might be surprising to learn that turbulence is actually worse in the daytime. In the early morning and night time, wind speeds typically reduce, and thunderstorms clear up. Avoid turbulence and catch up on some sleep by choosing flights with an early morning or red-eye departure!
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).
