In hover mode, the wind information can be updated via CDU INDEX Progress page or reflect winds captured when decelerating through which KIAS?

• A. Fifty KIAS
• B. Forty KIAS
• C. Forty-Five KIAS
• D. Fifty-Two KIAS

Answer: (A)

In hover, the wind information you rely on is refreshed at a specific deceleration point to ensure the data reflects the actual wind you’ll experience at low speed. The system is designed to update the wind vector when you decelerate through fifty knots indicated airspeed. You can also manually update it via the CDU INDEX Progress page if you want to refresh the wind data without waiting for that deceleration threshold. The other speeds don’t trigger the automatic wind refresh, so they aren’t the correct trigger.
