When running, L or R Oil Level LO status message appears below which percentage?

• A. 50%
• B. 57%
• C. 60%
• D. 65%

Answer: (B)

Oil quantity is continuously monitored and displayed as a percentage. There is a defined low-limit for triggering warnings, and on the CRJ-550 that threshold is 57%. When the oil quantity for the left or right engine drops to 57% or below, the L or R Oil Level LO message is shown to alert you that oil quantity is insufficient to sustain normal operation. This specific value is chosen to provide a reliable warning margin, accounting for sensor accuracy and temperature effects, so you can plan maintenance or a safe diversion before the situation becomes critical.
