用法筆記
Distinguish from the 'collective' — the cyclic controls horizontal direction (forward/backward/sideways), while the collective controls vertical movement (altitude). Often referred to simply as 'the cyclic' in helicopter training.
常見錯誤
☓ 'The pilot adjusted the cyclic to change altitude.' ✅ 'The pilot adjusted the cyclic to change direction.' — The cyclic controls horizontal movement, not altitude. The collective control handles altitude.
