The opposite direction, ±180° kept in 001–360: a bearing TO the station is the reciprocal of the radial FROM it, and runway 9's far end is runway 27.

Reading the screen: cyan is a value you entered, green is a computed result, amber means a field still needs input or the entry needs a CHECK. SOLVED lights when every result is computed; STO keeps a value to reuse in another function; the line-select keys beside the screen pick the field the keypad edits.
How this is computed
The opposite direction, ±180° kept in 001–360: a bearing TO the station is the reciprocal of the radial FROM it, and runway 9's far end is runway 27. Uses the same reciprocal helper as the crosswind sim core (computed geometry; scripts/test-crosswind-core.ts).
