How far can a plane drop in turbulence?

Turbulence, associated with thunderstorms, can be extremely hazardous, having the potential to cause overstressing of the aircraft or loss of control. Thunderstorm vertical currents may be strong enough to displace an aircraft up or down vertically as much as 2000 to 6000 feet.

By 2050, pilots around the world can expect to encounter at least twice as much severe clear-air turbulence, Williams found in his research. Clear-air turbulence is what caused a Lufthansa flight traveling from Texas to Germany to unexpectedly drop 1,000 feet this past week.

While turbulence can feel scary, airplanes are designed to withstand massive amounts of it. A plane cannot be flipped upside-down, thrown into a tailspin, or otherwise flung from the sky by even the mightiest gust or air pocket, wrote pilot Patrick Smith on his site, AskThePilot.com.

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.

The recommendation is to keep autopilot ON during a turbulence encounter. A pilot may be tempted to “fight against turbulence” when manually flying the aircraft and may overreact to sudden changes in the trajectory in some cases.

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.

MORE DETAILS

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.

An especially insidious form of turbulence has gotten worse because of climate change, according to new research. It's turbulence that forms in cloudless skies that's typically invisible to a plane's radar, called clear-air turbulence. And it's projected to become a bigger problem as the world warms.

Reflecting this increase in miles flown, preliminary estimates of the total number of accidents involving a U.S. registered civilian aircraft increased from 1,139 in 2020 to 1,225 in 2021. The number of civil aviation deaths increased from 349 in 2020 to 376 in 2021.

The worst seats on an airplane for turbulence are the jump seats in the back of the plane, where the flight attendants sit, followed by the passenger seats towards the back of the aircraft.

Using weather radar
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.

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.

A rough estimate of the probability of an airplane going down due to an emergency is about 1 in 11 million, meaning it would take us quite a few lifetimes before actually experiencing a plane crash. That's a whopping 0.00001% chance that something will go terribly wrong on your flight.

Periods of turbulence last an average of only 10 to 15 minutes, though it may seem like an eternity. Dr. Chris Manno, a pilot, professor, author, and current Boeing 737 captain for a major U.S. airline, is trained to deal with turbulence, but notes that airplanes are just as primed to take whatever weather is ahead.

Airplanes are built very sturdily. In fact, there's a lot of countermeasures built into the engineering of an airplane much like a car has different things to make a smooth ride on a bumpy road, airplanes have so many parts to it that's built into the aircraft to be able to deal with and safely handle the turbulence.

If you want to take it one step further, you can look at free turbulence forecast maps provided by TurbulenceForecast.com. Turbulence Forecast also offers a personalized forecast 2-12 hours before your flight for $14.99. I've never done it but I'm sometimes tempted.

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.

While no aircraft can avoid turbulence, passengers may feel less turbulence in widebody aircrafts, as they're larger and heavier airplanes.
