Istanbul → Seoul route, 7,923 km. Crosses the Balkans, the Mediterranean, and Anatolia. Winter jet stream may cause light bumps at cruise altitude; summer is typically smooth.
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.
How reliable is this forecast?
The forecast is computed from Open-Meteo using NOAA + UK Met Office WAFS wind data — the same sources pilot dispatchers use. No weather forecast is 100%; treat this as direction, not a guarantee.
How do pilots know about turbulence ahead of time?
Before each flight, pilots get a wind map briefing, ICAO SIGMET (significant meteorological advisories), and pilot reports (PIREPs) from other aircraft. In flight, they stay in active contact with ATC and nearby aircraft.
