Morphology

unscheduled = scheduled (transparent) = un + schedule + ed

Formed by productive negation 'un-' + 'scheduled', so the meaning 'not planned' is directly derived.

Etymology

Unscheduled breaks into un- meaning 'not' and schedule meaning a 'written plan' or 'timetable'. So an unscheduled event is 'not on the plan' or 'not at a set time', which is why we call a surprise meeting, stop, or outage 'unscheduled'.
