Route Map
Comprehensive Flight Profile

Flight Altitude Profile
  • X-axis: Distance along route (km)
  • Y-axis (left): Aircraft altitude (feet)
  • Blue = Climb phase
  • Green = Cruise phase
  • Orange = Descent phase
Pilot Reports (PIREPs)

Real turbulence reports from pilots who recently flew near your route:

  • Green = Smooth (no turbulence)
  • Yellow = Light turbulence
  • Orange = Moderate turbulence
  • Red = Severe turbulence
Tip: Look for areas where multiple indicators coincide (e.g., pilot reports + AI forecast + wind changes) to identify the most likely turbulence zones.
