Regardless of the position of the Emer light switch, the F/A switch can activate the Emergency Lights.

• A. True
• B. False
• C. Only when Master Warning is active
• D. Only on the ground

Answer: (A)

The emergency lighting system on the A320 can be activated through more than one control path, so the crew can illuminate the cabin even if one control source is not in the position they expect. The Flight Attendant control (F/A switch) energizes the emergency lighting circuit independently of the position of the Emer light switch. That means, when the F/A switch is activated, the emergency lights—escape path lighting and exit signs—can come on regardless of whether the Emer light switch is ON, OFF, or in another position. This design ensures that in an emergency, the cabin can be illuminated for safe evacuation even if the Emer light switch isn’t set to enable auto or manual operation. The Emer light switch mainly governs the normal/automatic control path and testing, but it does not prevent manual illumination via the F/A switch.
