What is the maximum braking time in seconds?

• A. 10 seconds
• B. 13 seconds
• C. 12 seconds
• D. 15 seconds

Answer: (B)

Braking time is the period from the moment you apply maximum braking until the helicopter comes to a complete stop, and it’s bounded by equipment and safety limits. In this scenario, the maximum allowable duration is set at 13 seconds to ensure you can achieve a controlled stop without overheating tires or brakes or exceeding safe deceleration limits.

Among the options, 13 seconds is the upper bound specified for this maneuver, making it the correct choice. A shorter time (like 10 seconds) would imply braking more aggressively than the standard allows, risking brake overload or loss of control, while a longer time (like 15 seconds) would exceed the allowed limit and could lead to excessive brake wear or unsafe stopping behavior. The 12-second option is below the maximum, so it’s not the designated limit.
