About — Time to Fly?

Time to Fly? is built to help paramotor pilots spot potential flight windows quickly. Instead of digging through pages of forecast data, this tool highlights the next morning and evening opportunities at a glance.

How flight windows are identified

• Primary windows: The periods around sunrise and sunset are scanned as candidate morning and evening windows.
• Weather inputs: Hourly forecast values — wind speed, gusts, temperature, visibility, precipitation probability, and timestamps — are used to construct and score each window for the selected location and time zone.
• Classification: Each hour is labeled with a status such as Smooth, Bumpy, Very Bumpy, Wind High, or Thermic to indicate expected flight begin and end times, and quality.
• Low-light reminders: Early-dawn and late-dusk periods are flagged as With Strobe to note visibility considerations and lighting requirements.
• Thermic activity: Hours likely to produce thermal turbulence are highlighted to help pilots avoid rough air during takeoff and landing periods.
• Window trimming: Very short windows, windows already in the past, or windows overridden by poor conditions are removed so only meaningful upcoming opportunities are shown.

When a window is eliminated entirely

Flight windows are removed when conditions exceed conservative safety limits, ensuring only realistically flyable periods are shown. A window is excluded if any of the following apply:

• Rain risk: Precipitation probability ≥ 40% or measurable rain is forecast
• Visibility: < 1 mile (1.6 km)
• Winds: Sustained > 12 mph (19 km/h) or gusts > 14 mph (23 km/h)
• Flight duration: Less than two hours of usable flyable time remain after applying the filters above

These rules keep the display focused on windows that are realistically usable and reduce the chance of planning around marginal or unsafe conditions.

Notes

• This page provides a quick, conservative overview — it is not a substitute for a full pre-flight weather briefing or checking local NOTAMs.
• For detailed altitude-level winds, follow the provided PPG.report link when available for a given window.
