Do bigger planes feel less turbulence? Usually, yes. Here's why

Key facts

• The Aviation Weather Center's thresholds for moderate turbulence rise with aircraft weight: an EDR of 0.16 for light aircraft, 0.20 for medium and 0.24 for heavy (over 300,000 lb). [1]
• ICAO notes that a heavy aircraft needs a higher EDR to experience severe turbulence, and a light aircraft a lower one. [2]
• In NACA's classic gust-load formula, the extra g from a gust grows with wing area, airspeed and gust strength, and shrinks as the airplane's weight grows. [3]
• US rules require every airliner's structure to carry at least 2.5 g, and smaller transport airplanes must be designed for more, up to 3.8 g. [4]
• In one Boeing 737-900ER turbulence accident, peak g in the rear cabin was about 0.2 g larger than at the center of gravity; in an Embraer 190 case the differences along the cabin were smaller. [5]
• Boeing describes flight controls that read accelerometers and gust sensors and move the elevators, ailerons and rudder within milliseconds to oppose disturbances. [6]

Why heavier planes ride the same air more gently

Wing loading is an airplane's weight divided by the area of its wings. It's the key to how hard a gust can shove an airplane.

When an airplane flies into an up- or downdraft, the air meets the wing at a slightly different angle, and the wing's lift jumps or dips for a moment. That extra force depends on how much wing there is and how fast the airplane is flying. What it has to move is the whole airplane. More weight per square foot of wing means the same extra force produces a smaller acceleration, so you feel a smaller bump.

Engineers wrote this down decades ago. NACA, NASA's predecessor, used a gust-load formula in which the airplane's peak acceleration equals the wing's lift slope × air density × wing area × airspeed × gust speed × a correction factor, all divided by twice the airplane's weight [3]. Put simply:

• More wing area or more speed: a bigger jolt from the same gust.
• More weight: a smaller jolt from the same gust.
• Weight per wing area (wing loading): the higher it is, the smoother the ride.

The same formula explains why pilots slow down in rough air. "Turbulence penetration speed" is the maximum airspeed an airplane should fly at in turbulent air [5], and a slower airplane takes a gentler jolt from each gust.

The same air, three different rides

Meteorologists measure turbulence with the eddy dissipation rate (EDR), a measure of the air itself that doesn't depend on the airplane, like a sea state that doesn't depend on the size of the ship [5]. To turn it into what a crew will feel, the Aviation Weather Center uses different thresholds for each weight class [1]:

Here's what that means for one patch of air, read straight from those thresholds:

So in air a medium jet rates as moderate, a heavy jet may rate it as light. ICAO makes the same point and says the threshold for a specific type should be defined in its technical documentation [2].

Is turbulence worse on smaller planes?

The ride, often yes. The safety, no. Every airliner, from a regional jet to a jumbo, must meet the same US structural rules: its structure must carry a limit load of at least 2.5 g without damage [4]. For smaller transport airplanes the minimum is higher. The rule sets it at 2.1 + 24,000 / (weight + 10,000 lb), never less than 2.5 g, and it need not exceed 3.8 g [4]. An airplane designed at 30,000 pounds, for example, works out to at least 2.7 g.

In other words, the smaller airplane feels the bump more, and it's built for bigger bumps. To see how much of the limit an ordinary bump uses, read is turbulence dangerous?

Pilot reports reflect the difference too: a "moderate" from a small regional jet and a "moderate" from a heavy wide-body describe different air, which is one reason forecasters prefer EDR [1][5]. Our guide to turbulence levels explains the scale.

What's the smoothest plane to fly on?

Honestly: a heavy wide-body, such as a 777, A330 or A380, will usually ride the same air more gently than a narrow-body or a regional jet [1]. But the air on the day matters more than the airplane. A heavy jet near thunderstorms will be bumpier than a small jet in smooth air, and the table above shows why: a heavy jet in air with an EDR of 0.50 rates it moderate, while any airliner in air below 0.15 sees nothing worse than light [1].

Modern flight controls help as well. Boeing describes two functions: gust suppression, which counters whole-airplane movements, and modal suppression, which damps the bending of the wings and body. They read accelerometers, airspeed and angle-of-attack vanes and dedicated gust sensors, and Boeing says this approach will be applied to all its future airplanes [6].

If you have a choice of flights, the weather often matters more than the airplane type: the best time to fly for less turbulence covers time of day and season, and what causes turbulence explains the air itself.

Where you sit matters too

Size isn't the only thing you can choose. Bumps aren't the same along the cabin. In the NTSB's estimate for one Boeing 737-900ER accident, the rear cabin's peaks were about 0.2 g larger in magnitude than the center of gravity's, while the cockpit generally saw the smallest swings; in an Embraer 190 case the differences were smaller [5]. See the best seat for turbulence for how to use that when you book.

Do private jets feel more turbulence?

Often, yes, for the same reason. Business jets are lighter than big airliners: the Aviation Weather Center puts a Learjet 23 in its light class and a Gulfstream in its medium class [1], so the same air rates rougher for them than for a heavy airliner. They're designed and flown with that in mind.

How Sorapuff helps

Sorapuff's free bump meter measures the bumps on your airplane, whatever its size: the change in g at your seat, from your phone's motion sensors, in airplane mode. It shows each bump next to the 2.5 g the airplane is built for, and after landing the Bump Report shows how much of that margin your biggest bump used. The route forecast shows how likely bumps are in the air you'll fly through. Both are information, not a safety device: always follow your crew.

FAQ

Is turbulence worse on smaller planes?

The ride usually is. A smaller, lighter airplane has less weight behind each square foot of wing, so the same gust jolts it more. Forecasters build this in: the Aviation Weather Center counts moderate turbulence from an EDR of 0.16 for light aircraft but 0.24 for heavy jets. Smaller airliners are built to the same or higher structural limits, so they're just as safe.

What is the smoothest plane to fly on?

A heavy wide-body such as a 777, A330 or A380 usually rides the same air most gently, because of its high weight and wing loading. But the weather on the day matters more than the airplane: a big jet near thunderstorms is bumpier than a small one in smooth air. Your seat also changes how bumps feel.

Do bigger planes handle turbulence better?

They feel it less, but all airliners handle it safely. Every airliner must carry at least 2.5 g without damage, with a safety factor of 1.5 on top, and smaller transport airplanes must be designed for even higher loads, up to 3.8 g. A bigger plane gives a gentler ride, not a safer one.

Do private jets feel more turbulence?

Often, yes. Business jets are lighter than big airliners, so they feel the same air more strongly. The Aviation Weather Center puts a Learjet 23 in its light class, where turbulence counts as severe from an EDR of 0.36, compared with 0.54 for heavy airliners. They're designed and flown with this in mind.

Does the A380 feel less turbulence?

Generally, yes. The A380 is in the Aviation Weather Center's heavy class with the 747 and 777, where the same air is rated a level gentler than for medium jets like the A320 or 737. It still feels turbulence, though, and pilots still turn on the seat belt sign when bumps are expected.
