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 – 54mSmooth

Nothing significant forecast here.

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.

Boeing 717-200

Recently flown with: B712, B717.

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.

The app draws the route of AS1120 over the moving forecast: bumpy air, storms and the winds at cruise height. Scrub through the flight hour by hour.

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.
