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.

FCO · Take off0m – 54mSmooth

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.

Cruise54m – 1h 56mLight

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.

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 Sao Paulo11h 22m – 12h 5mLight

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

From 11h 3m to 11h 19m into the flight the forecast has thunderstorms 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 a global weather model, and corrected with turbulence reports radioed in by pilots in the last few hours. Each new model run replaces the forecast.

Planned route · timing and conditions may change.

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 AZ674

Will AZ674 be bumpy?

For the flight on Sat 7 Nov: Smooth most of the way, with occasional light bumps after takeoff. Barely moves your drink. The forecast is replaced with every new weather model run, so check back closer to departure.

What plane flies AZ674?

Recently AZ674 has been flown with: Airbus A350. Airlines can swap the aircraft until shortly before departure.

How long is AZ674?

What time does AZ674 leave?

AZ674 usually departs Rome at 22:20 local time and arrives in Sao Paulo at 06:25 local time. Times change; the app tracks the live schedule.

Is turbulence dangerous on AZ674?

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.
