Paragliding Weather and Local Wind Review

Resolve signed headwind and crosswind from true bearings, or compare component extrema across a complete wind direction and speed sector.

Calculate ground speed and track at a held heading, retaining sideways drift, backwards ground travel and the undefined zero-speed direction.

Solve the wind triangle for a desired ground track, showing heading and forward speed while identifying physically infeasible wind cases.

Calculate NWS wind chill with unit conversion and exact temperature and wind applicability checks, then save the observed conditions.

Calculate the NWS heat-index estimate with its simple method, Rothfusz regression and humidity adjustments, keeping model limits visible.

Record completed flights with UTC times, wing identity and debrief notes; summarize airborne hours and distance with local history and exports.

Calculate slope angle, grade, rise and sloping length from explicit geometry, with clear units and no inferred terrain difficulty rating.

Calculate wing loading on an explicit area basis and add complete carried mass to compare documented wing and reserve mass boundaries.

Calculate equipment service due dates and recorded hours remaining from actual manual intervals, with explicit calendar and review-date rules.

Model glide arrival height with wind and compare supplied polar points against a complete terrain profile and required-height allowance.

Calculate an observed descending ground-glide ratio or compare supplied still-air polar points, with explicit speed, sink and measurement bases.
