Big Plane or Small Jet: Is One Safer?
2 min read
The short answer
Every passenger jet, big or small, must meet the same strict design standards before it can carry passengers. Regional airlines follow the same rulebook as the big airlines. Smaller planes do feel bumps more because they're lighter — but feeling more movement doesn't mean less safety.
The Same Standards for Every Jet
Before a new airliner can carry passengers, it must pass a demanding set of design rules. In Europe these are called CS-25, and in the US "Part 25". A 70-seat regional jet and a 400-seat jumbo meet the same requirements for strength, backup systems and testing.
Regional Airlines Follow the Same Rules
Smaller jets are often flown by regional airlines, sometimes on behalf of a big-name airline. In the US, the rules changed in the 1990s to create "one level of safety". Since then, scheduled flights with ten or more passenger seats have followed the same rulebook as the major airlines. In Europe, every airline follows the same EU rules.
That means the same pilot licences, the same regular checks and the same maintenance standards.
Why Small Planes Feel Bumpier
A small jet is lighter, so the same gust of air moves it more. Think of a small boat and a big ship on the same waves. The small boat rocks more, but it's built for those waves.
Every airliner's structure is designed for far stronger forces than you'll ever feel. Read why turbulence is uncomfortable but not dangerous.
On a smaller plane you may also feel each turn more and hear the engines more clearly. These are differences in comfort, not in safety.
What About Propeller Planes?
Most propeller airliners, such as the ATR and the Dash 8, are certified to the same large-aeroplane rules. Their safety depends mostly on who flies them and where. Read the honest picture in flying on a propeller plane.
Big Planes on Long Routes
Big planes often fly long routes over oceans. They follow extra rules for that, such as always staying within reach of an airport. Read flying over water.
The Bottom Line
Size changes how a flight feels, not how safe it is. If bumps bother you, choose a seat over the wings. That's where the ride is smoothest, whatever the size of the plane.
