Structs

WindSegment

One downrange wind segment. vertical_mps (m/s, positive = updraft) feeds straight into the segment’s wind vector via wind_vector (MBA-728); boundary-layer shear scales horizontal wind only, so vertical passes through unscaled wherever shear is applied on top of a segment.

Wind condition handler for trajectory calculations

Functions

parse_wind_segment_str

Parse a "SPEED:ANGLE:UNTIL_DISTANCE[:VERTICAL]" string into a WindSegment (speed_kmh, angle_deg, until_distance_m, vertical_mps).

wind_vector

THE wind-vector builder (McCoy frame: x downrange, y up, z right). Horizontal wind uses the wind-FROM convention (0 = headwind, PI/2 = from the right); vertical_mps is positive-updraft and lands on y UNSCALED — boundary-layer shear models scale horizontal flow only (MBA-728 decision).
