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.
AOI · Take off0m – 15mSmooth
Nothing significant forecast here.
The first minutes are flown through the lowest, liveliest air. Sun-warmed ground sends up thermals and wind bends around hills, so a bump or two while climbing is normal. It fades as the aircraft climbs into the smoother air above.
Cruise15m – 2h 12mLight
Mountain waves
Wind blowing over a mountain range makes waves in the air downstream, the way water ripples over rocks in a stream, and those waves can reach cruising height. They are forecast from the same wind and terrain data used here, so the crew knows where they are before departure.
At cruise the air is thin and cold, and most of it is calm. The bumps up here come from the jet stream, a band of fast wind whose edges stir the air, or from waves set off by mountains far below. This forecast shows where those edges are.
Descent into London2h 12m – 2h 20mModerate
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's the most common kind of turbulence, and it's on the crew's charts before departure. When they meet it, they slow to a set turbulence speed and ride it out.
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.
Thunderstorms near the route
Between 18m and 2h 8m into the flight the forecast has a few thunderstorms, some on the planned line itself.
The ride line can stay calm with storms nearby. It follows the planned track at cruise height, above most storm tops. Pilots don't fly through storms: the weather radar in the nose shows each one, and the rule is to stay at least 20 nautical miles (about 37 km) away. Usually that means a detour of a few minutes.
The closest of these is within the 20 nm the crew has to keep, so expect a small turn around it. The line on the map is the planned route; the real track will bend around the storm.

Bigger and heavier aircraft are moved less by the same patch of air, and every airliner is designed for much stronger turbulence than it will meet.

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
- Clear bumps. Drinks may slosh and the belt sign comes on. Uncomfortable, but the pilots stay in full control.
- Severe
- Strong jolts, and loose items can move. This is rare, and it's why 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 3 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 independent weather models behind this forecast agree on this ride.

Why turbulence isn't dangerous
Aircraft are designed for much worse.
Airliners are tested to loads well beyond anything turbulence produces. The wings are meant to flex, so seeing them move is normal.
Crews know where it is.
Your crew has forecasts like this one, live reports from other pilots and their own weather radar, and they change altitude to stay out of bumpy air.
Keep your belt on.
Almost all turbulence injuries happen to people who are standing or not buckled in. Seated with your belt on, turbulence is uncomfortable but not dangerous.
Questions about FR125
Will FR125 be bumpy?
For the flight on Fri 23 Oct: Smooth or light most of the way, with occasional moderate bumps on descent. The belt sign will likely come on. The forecast is replaced with every new weather model run, so check back closer to departure.
What plane flies FR125?
Recently FR125 has been flown with: Boeing 737 MAX. Airlines can swap the aircraft until shortly before departure.
How long is FR125?
About 2h 20m gate to gate from Ancona to London, a distance of about 1,342 km.
What time does FR125 leave?
FR125 usually departs Ancona at 17:40 local time and arrives in London at 19:00 local time. Times change; the app tracks the live schedule.
Is turbulence dangerous on FR125?
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.
