Brake temperatures must be what color for takeoff?

• A. Green
• B. Yellow
• C. Amber
• D. Red

Answer: (A)

Brake temperatures are shown in color to indicate whether the brakes are within a safe takeoff range. Green means the brakes are cool and within the acceptable takeoff limits, giving full braking performance if needed. Warmer colors (yellow/amber/red) signal increasing heat and potential brake fade, which can compromise braking effectiveness during an aborted takeoff or landing roll. Because of that, takeoff is only permitted when the brake temperature is green.
