After an aircraft has started its takeoff roll, you should cancel the takeoff clearance for which reason?

The key idea is that once an aircraft has started the takeoff roll, the decision to abort is driven by safety. If continuing the takeoff would be unsafe—due to an engine failure, fire, loss of control, an obstacle on the runway, or any other hazardous condition—the proper action is to cancel the takeoff clearance and abort. Weather or runway condition concerns are factors that should be resolved before or during the decision to take off; if they create a safety risk while rolling, they fall under the safety reason for stopping. A pilot can request an abort if they judge it unsafe, but the fundamental reason for canceling after rolling is safety.
