This may result in the power required to hover ______ the limits of the aircraft.

• A. Exceeding
• B. Within limits
• C. Decreasing
• D. Approaching

Answer: (A)

Power margins in hover are about whether the helicopter can supply enough power to stay in place. The power required to hover increases with heavier weight, higher density altitude, and hotter air. When that required power exceeds what the helicopter can safely deliver (the power available), you’re beyond the aircraft’s hover limits. In that case, a stable hover isn’t possible, and you’d need to descend, land, or reduce weight to regain a safe margin. The other phrases would imply the hover capability is still within limits, or that the required power decreases or only approaches the limit, which isn’t true under those conditions.
