FAQ
Is turbulence dangerous?
Modern aircraft are engineered to handle even the heaviest turbulence. Turbulence is uncomfortable, but not a structural threat. Pilots can change altitude or routing to find calmer air.
Which times of day are smoothest?
Early morning and night flights tend to be smoother — thermal currents from solar heating can cause mild bumps on afternoon departures.
Why are there light bumps at cruise altitude?
At cruise altitude (around 10-12 km), wind shear from the jet stream can produce brief clear-air turbulence. It usually lasts a few minutes; the pilot turns on the seatbelt sign, sometimes adjusts routing.
