At what indicated fuel quantity do the left and right fuel quantity arrows on the AEDD turn yellow?

The correct answer is 150 lbs. The Aviation Electric Display Data (AEDD) in the T-6 aircraft provides critical information about fuel status, and the color coding is designed to give pilots a clear visual indication of fuel quantity levels. When the indicated fuel quantity drops to 150 lbs, the left and right fuel quantity arrows turn yellow, signaling to the pilot that the fuel levels are getting low and require attention. This warning system helps ensure that pilots are aware of their fuel situation and can take appropriate measures to manage fuel consumption or prepare for a landing if necessary. It's an important aspect of fuel management and safety within the aircraft's operational protocol.
