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

The FA indicator panel displays amber when the sterile flight deck is in effect on the ERJ 175. This color coding serves as an important visual indication to the flight attendants that they need to refrain from certain activities, such as regular service and non-essential communication, as this period usually coincides with critical phases of flight like takeoff and landing. The use of amber effectively catches the attention of the cabin crew, signaling them to prioritize safety and adhere to the procedures associated with the sterile flight deck policy.

Colors like green, red, and blue are used in different contexts on the aircraft’s systems, but amber is specifically designated to indicate the sterile flight deck status, ensuring that crew members are alert and focused during those crucial times.
