In hover mode, the wind information displayed will either represent winds captured as the aircraft decelerates through which KIAS or winds manually updated via CDU INDEX Progress page?

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

Answer: (B)

In hover mode the wind shown is taken from a wind sample captured as you slow through fifty knots indicated airspeed, or from winds manually entered on the CDU INDEX Progress page. Fifty KIAS is used because it provides a stable, representative wind reference for hover conditions when forward speed is near zero and rotor downwash effects dominate. If the automatic capture isn’t current, or winds have changed, you can update the displayed wind by entering the current value via the CDU INDEX Progress page. The other speed thresholds aren’t used for the hover wind reference, so they aren’t correct.
