On which panel does the L or R OIL PRESS LO warning light appear?

• A. The main instrument display
• B. The annunciator panel
• C. The engine control panel
• D. The overhead panel

Answer: (B)

Warning indicators for system faults are grouped on the annunciator panel. The L or R OIL PRESS LO light signals that the left or right engine oil pressure is too low, and such warnings are placed on the annunciator panel so they’re quickly visible to both pilots. The main instrument display shows flight data and engine parameters, but not dedicated warning lights; the engine control and overhead panels handle controls and systems rather than this warning. So the light appears on the annunciator panel.
