There's a moment you don't see from the cabin: 60-90 minutes before the doors close, the pilot is sitting in the dispatch office reading a document. Inside it: everything they need to know about this flight — route, weather, fuel, alternates, turbulence maps. Unlike the passenger in the cabin, the pilot has the flight on paper before stepping on board.
OFP — Operational Flight Plan
The core briefing document: the Operational Flight Plan, or OFP. A 50-200 page PDF, continuously updated by flight planning software. The pilot downloads the final version right before the flight.
What's in it:
- Route: each waypoint coordinate, altitude, speed
- Fuel plan: primary, alternate, contingency reserve
- Weather reports: departure, arrival, alternate airports' METAR + TAF
- Current SIGMETs: volcanic ash, storms, severe turbulence warnings
- WAFS turbulence charts: EDR forecast at each flight level
- Upper-air data: wind, temperature, jet-stream behavior
- PIREPs from other aircraft: recent reports from pilots flying the same area
The single most important feature of this document, which the passenger never sees: turbulence zones aren't a surprise. The pilot knows most of them in advance and either routes around them or adjusts.
WAFS — the world's turbulence map
World Area Forecast System. ICAO-mandated, produced jointly by NOAA (US) and the UK Met Office. Global turbulence forecast, updated every 6 hours. Every commercial pilot's briefing includes a slice of these charts.
On these charts the pilot sees turbulence bands along the route, color-coded. If there's a severe band, the pilot considers rerouting or changing altitude — usually climbing or descending 1,000-2,000 ft to fly above or below the layer.
Turbuly uses this WAFS data — the same source the pilot is briefed on. The only difference: it's served to passengers in anxiety-friendly language.
PIREP — real-time pilot reports
Pilot Report, shortened. If a pilot encounters turbulence in flight, they radio a report to ATC, who broadcasts it; pilots flying the same area see it. Concrete and specific: "FL340 over Bulgaria entry, light turbulence, 2 minutes."
PIREPs are different from forecasts: they're actual real-time experience. Dispatch sees them and updates the next flight's briefing. Pilot knowledge isn't built on models alone — it's models plus live feedback from the sky.
The cabin crew briefing
The OFP briefing happens between pilot and dispatcher. Once the pilot boards, they brief the cabin crew separately — turbulence expectations are a standing topic. "We expect 15-20 minutes of light turbulence over Romania mid-cruise; service will pause during that window."
When the cabin crew reminds you to buckle up, that warning came from the briefing. Not a surprise — a plan.
The reassurance you can't see
By the time you board, the pilot has already:
- Reviewed the route's turbulence risk in advance
- Read WAFS data on where to expect bumps
- Read PIREPs from pilots who just flew the same path
- Built a fuel plan with backup routes
- Briefed the cabin crew and scheduled service around it
The briefing document isn't visible through the cabin window. But behind every flight decision sits 60-90 minutes of preparation. Turbulence may feel like a surprise in the cabin; in the cockpit, it isn't.
