Where is the potable water levels displayed?

• A. On the overhead panel above the galley
• B. In the cockpit ECAM display
• C. On the forward cabin wall monitor
• D. AFT FA panel at FA2 station

Answer: (D)

Potable water quantity is a cabin service parameter that flight attendants monitor during service and between flights. On the E190, this information is displayed at the aft flight attendant panel at the FA2 station, so crew can check water levels from the rear of the cabin. The cockpit ECAM display is for pilots and aircraft systems, not potable water data, and the other options are not where this information is shown. The aft FA panel at FA2 is specifically designated for monitoring potable water (and related service information), making it the correct location.
