Bumpiness along the flight
Takeoff on the left, landing on the right. The higher the line, the bumpier the air the forecast expects at that moment.
Where, and why
The flight split into stretches: how bumpy each is forecast to be, and what causes it.
Cruise0m – 1h 10mLight
Jet-stream wind shear
Where fast air slides over slower air, usually at the edge of the jet stream, the boundary ripples like a flag. It is the most common kind of turbulence and it never comes as a surprise: it is on the crew's charts, and they slow to a set turbulence speed and let the aircraft ride it out.
At cruise the air is thin and cold, and most of it is calm. The bumps up here come from the jet stream, a river of fast wind whose edges stir the air, or from waves set off by mountains far below. This forecast maps exactly where those edges sit.

Descent into Shanghai8h 11m – 8h 50mSmooth
Nothing significant forecast here.
Coming down means flying back through the low, lively air near the ground: afternoon thermals, gusts around the airport. It is the busiest part of the flight for the crew, and the part they train for most.

The aircraft
What MU248 is flown with, and how it handles bumpy air.
Airbus A330-300
Bigger and heavier aircraft are moved less by the same patch of air, but every airliner is built for far more than turbulence produces.

What each level feels like
- Smooth
- Calm air. Nothing to notice beyond the hum of the engines.
- Light
- Gentle ripples and the odd dip. Drinks stay put, and walking to the toilet is fine.
- Moderate
- Distinct bumps. A drink might slosh and the belt sign comes on. Uncomfortable, and the aircraft is in full control throughout.
- Severe
- Strong jolts, and loose items can move. Rare, and the reason the belt sign exists: crews slow down and change altitude to get out of it.
How this forecast is made
The planned route is sampled from gate to gate at the altitude the aircraft flies, through 2 independent global weather models, and corrected with turbulence reports radioed in by pilots in the last few hours. Each new model run replaces the forecast; nothing here is a guess from the airline's history.
The weather models behind this forecast mostly agree; the bumpy patches may shift a little.
Planned route · timing and conditions may change.
Why the bumps are only bumps
Built for it.
Airliners are tested to loads far beyond anything turbulence produces; the wing flexing you can see is by design.
Seen in advance.
Your crew flies with forecasts like this one, live reports from other pilots and their own weather radar, and they change altitude to stay out of the bumpy air.
The belt is the whole story.
Turbulence injuries almost always involve someone standing or unbuckled. Seated with the belt on, it is a bumpy road and nothing more.
Questions about MU248
Will MU248 be bumpy?
For the flight on Tue 6 Oct: Mostly smooth. About 155 minutes of light bumps after takeoff. Barely moves your drink. The forecast is replaced with every new weather model run, so check back closer to departure.
How long is MU248?
About 8h 50m gate to gate from Moscow to Shanghai, a distance of about 6,851 km.
What time does MU248 leave?
MU248 usually departs Moscow at 16:50 local time and arrives in Shanghai at 06:40 local time. Times change; the app tracks the live schedule.
Is turbulence dangerous on MU248?
Turbulence is uncomfortable, not dangerous to the aircraft. Airliners are certified for loads far beyond anything turbulence produces, and crews plan around the bumpy patches with the same kind of forecast as this one. Injuries are almost always to people who were standing or unbuckled, so keep your seatbelt fastened whenever you're seated.
How accurate is this turbulence forecast?
It is a forecast, so it is best within a day or so of departure and improves with every model run. The bumpy patches it finds are usually in the right place, but their timing can shift by a few minutes and the crew may change altitude to avoid them, so the ride you get is often smoother than the forecast.
