3. Learning Context

• Grammar Focus: The と conditional expresses automatic or natural results — when A happens, B inevitably follows.
• Usage Note: Unlike たら or ば, と is commonly used for mechanical/natural consequences (e.g. pressing buttons, weather effects).
• Context: Lesson set on a plane — exploring seat controls, monitors, and flight scenarios.
• Cultural Note: Mt. Fuji (ふじ山) can be seen from flights on certain Tokyo routes. Japanese airlines often make in-flight announcements about it, and some provide seat guides for the best aerial views.
