Conceptual Metaphor
OPPORTUNITY IS A WINDOW (that opens and closes); TIME IS A LIMITED RESOURCE.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation to 'окно запуска' outside of technical aerospace contexts; it may sound odd. In business, use 'благоприятный момент для запуска' or 'окно возможностей'.
Common Mistakes
- Using it for any deadline (it implies optimal, not just final, timing).
- Confusing it with 'launch date' (a single day vs. a period).
- Using it without the article 'the' (e.g., 'We have launch window').
