Which action is part of the procedure for conducting a rejected takeoff?

In the context of conducting a rejected takeoff, applying maximum braking and identifying stopping distance is a critical part of the procedure. When a decision is made to abort the takeoff, the flight crew must immediately apply the brakes to decelerate the aircraft effectively. This involves ensuring that they are using maximum braking to stop the aircraft within the available runway length. Identifying the stopping distance is equally important, as it helps the crew assess whether they can safely bring the aircraft to a full stop before any potential obstacles.

The other choices do not align with the proper protocol for a rejected takeoff. Increasing thrust to regain speed is counterproductive in this situation, as the focus should be on stopping the aircraft rather than continuing to accelerate. Similarly, calling for emergency services is typically only necessary after determining the situation post-rejected takeoff, depending on the circumstances surrounding the decision. Continuing the takeoff despite issues goes against the very purpose of a rejected takeoff, which is to address problems before reaching a critical point in the takeoff roll. Therefore, choice A accurately reflects the correct actions to take during a rejected takeoff.
