What is the maximum braking speed defined as?

The maximum braking speed is defined as the highest speed at which an aircraft can come to a complete stop without exceeding the design limits of the brakes. This speed is critical during landing and taxiing scenarios, where controlled deceleration is necessary to ensure safety and prevent damage to the aircraft's braking system.

When an aircraft lands, various factors come into play, such as tire condition, runway surface, and environmental conditions, all of which can affect braking performance. Understanding the maximum braking speed helps pilots ensure they engage the brakes effectively while remaining within the operational limits of the aircraft's braking system.

The other options pertain to different aspects of aircraft operation, but they do not accurately reflect the definition of maximum braking speed. For example, the speed at which an aircraft can operate with minimum power or the maximum speed for a safe ascent do not relate to the braking capabilities directly. Similarly, maximum takeoff speed concerns the speed necessary for a successful liftoff rather than the stopping efficiency after landing.
