Final answer:
The taxiway ending marker indicates that the taxiway does not continue, alerting pilots to stop to prevent them from entering areas not suitable for taxiing.
Step-by-step explanation:
The taxiway ending marker indicates that the taxiway does not continue. This is essential for pilots to recognize the end of the taxiway to prevent the aircraft from inadvertently entering an area not designed for taxiing or landing. The taxiway ending marker does not identify areas where aircraft are prohibited, nor does it provide general taxiing directions to a named taxiway. It is simply a signal to the pilot that the taxiway has come to an end, and they should not proceed further along the current path.
