What color does the FA indicator panel display when the sterile flight deck is in effect on the ERJ 175?

When the sterile flight deck is in effect on the ERJ 175, the flight attendant (FA) indicator panel displays an amber color. This amber indication serves as a visual alert to the flight attendants that certain protocols are currently in place, particularly during critical phases of flight such as takeoff and landing. During these times, non-essential communications and activities are restricted to ensure safety and focus.

The choice of amber is significant as it represents caution, signaling that flight attendants should be particularly mindful of their responsibilities and the overall situation in the cabin during these critical phases. The use of this color helps to ensure that compliance with sterile cockpit procedures is easily recognizable by the crew.
