LO FUEL (YELLOW) threshold?

LO FUEL (YELLOW) threshold?

• A. Wing Tank < 600 LBS; Total Fuel < 1200 LBS
• B. Wing Tank < 500 LBS; Total Fuel < 1200 LBS
• C. Wing Tank < 600 LBS; Total Fuel < 1000 LBS
• D. Wing Tank < 700 LBS; Total Fuel < 1200 LBS

Answer: (A)

LO FUEL yellow is a caution that shows when you’re approaching minimum fuel reserves and need to reassess your plan. For the CRJ-550, this warning appears when both fuel in the wing tanks falls below 600 pounds and the total usable fuel falls below 1200 pounds. Having both conditions ensures you’re not misled by a low reading in one tank if the other tank and overall fuel are still adequate, and it prompts you to adjust flight plans or request priority handling before fuel becomes critical. Other threshold combinations don’t match the published criteria for this warning, so they wouldn’t trigger LO FUEL in the same way.
