What hazard is associated with exceeding the temperature limits for ground operations?

Exceeding the temperature limits for ground operations can lead to a risk of engine failure. The T-6A's engine is designed to operate within specified temperature limits to ensure optimal performance, longevity, and reliability. When these limits are surpassed, it can result in excessive wear and stress on engine components, potentially leading to overheating or failures. Proper management of temperature during ground operations is crucial to maintain engine integrity and avoid any malfunctions that could endanger the flight.

While increased fuel consumption and prolonged taxi times may be related to operating inefficiencies, they do not directly correlate with the immediate critical risk to engine functionality that comes from high temperature exposure. The chance of icing is also not relevant during ground operations in warm conditions, thus leading us back to the importance of adhering to temperature limits to prevent engine failure.
