In an emergency, which interphone button should be used to alert the pilot?

• A. Emergency Pilot Button
• B. Pilot Button
• C. PA Button
• D. ATTND Button

Answer: (A)

In an emergency, you need a direct, unmistakable alert that reaches the flight crew immediately. The interphone system includes a dedicated high-priority path to the pilots, designed to grab their attention right away. Pressing the Emergency Pilot control triggers that urgent alert, usually with a distinct tone and indication in the cockpit, so the captain or first officer understands action is required now.

The other options serve different purposes: the Pilot control would contact the flight deck but without the emergency priority; the PA button is intended for speaking to passengers; the ATTND button is for reaching cabin attendants. None of these provide the rapid, cockpit-focused alert that the emergency control delivers.
