Paragliding Cross-Country Route and Retrieval Planning

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

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

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

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

Calculate ground-distance travel time with unit conversion, or sum unequal-speed route legs and explicit circling, climb or delay allowances.

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

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

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

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

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