What is the normal operating range for fuel switches in the T-6?

In the T-6, it's essential to monitor both the light indicators and the fuel level gauge during operations. The fuel level gauge provides crucial information about the amount of fuel remaining in the tanks, which is vital for managing fuel consumption during flights. On the other hand, the light indicators serve as alerts that can indicate potential issues, such as low fuel levels, which must be addressed to avoid in-flight emergencies.

Monitoring only the fuel level would not provide a complete picture since fuel indicators may not always give early warnings of issues indicated by the light. Similarly, relying solely on the lights would mean ignoring the actual fuel level, which is an important metric for safe operations. The backup fuel gauge, while important in certain situations, does not replace the need to keep an eye on both the primary fuel level and the warning lights for comprehensive situational awareness. Therefore, both the light indicators and the fuel level gauge must be monitored closely to ensure safe and efficient flying in the T-6.
