Which indicator would be used to estimate remaining endurance at the current power setting?

• A. Fuel Time Remaining at Current Power Setting
• B. Fuel Flow Rate
• C. Fuel Used Since Reset
• D. Fuel Temperature

Answer: (A)

Estimating how long you can fly at the current power setting is about knowing how much fuel you have left and how fast you’re consuming it. The indicator that shows Fuel Time Remaining at Current Power Setting gives you the actual remaining time based on the current fuel on board and the current rate of consumption. It updates as you adjust power, so you see a direct read of endurance under the present settings. Fuel Flow Rate only shows how quickly you’re burning fuel right now, not how much time that fuel will last. Fuel Used Since Reset is just the amount of fuel consumed since the last reset, not a projection of remaining endurance. Fuel Temperature can affect performance but doesn’t indicate how much flight time remains.
