What might indicate an abnormal situation during T-6 operations?

An abnormal situation during T-6 operations is indicated by warning lights and visual indicators. These signals are designed to alert the pilot to any potential issues or malfunctions within the aircraft systems. For instance, warning lights might illuminate to indicate engine troubles, fuel system malfunctions, or electrical issues, which require immediate attention and can significantly impact flight safety.

In contrast, high altitude is not inherently indicative of an abnormal situation; it is a normal operational parameter for the aircraft, depending on the flight profile. Stable airspeed is also a normal condition, suggesting that the aircraft is flying properly without undesirable fluctuations that might indicate a problem. Normal engine sounds contribute to the assessment of the aircraft's operational status; if engine performance is as expected, it suggests no issues. Thus, the presence of warning lights and visual indicators is a critical factor in identifying deviations from normal operations that could warrant further investigation or action.
