Oil pressures during start are shown as which indicator on the cockpit displays?

• A. Amber Dashes
• B. White Dials
• C. Blue Bars
• D. Green Gauges

Answer: (A)

During start, the oil pressure reading isn’t yet established, so the CRJ-550 cockpit displays show amber dashes. The amber color flags a caution and the dash format communicates “no valid reading at the moment.” Once oil pressure develops, the display will switch to the normal readout format used for that parameter. White dials, blue bars, and green gauges are used for other states or parameters and would not indicate oil pressure during start.
