To alert the flight deck in an emergency, which keypad entry is used?

• A. ** (starstar)
• B. starstar
• C. #*
• D. PUSH TO TALK

Answer: (A)

To alert the flight deck in an emergency, you use two consecutive asterisks on the keypad. This specific sequence, starstar, is the designed emergency alert input for the 787’s crew alert system, so it’s recognized instantly by the cockpit and draws immediate attention from the pilots. The keypad is set up so that this rapid, unambiguous signal overrides normal call procedures to ensure a swift response. The other options aren’t defined as the emergency alert input—the push-to-talk control handles voice communication, not an alert to the cockpit. So the correct entry is pressing the star key twice.
