• B. Two HI chimes
• C. Three HI chimes
• D. Continuous chimes

Answer: (B)

The signal for entering or exiting the sterile flight deck on all CRJ aircraft is characterized by the sound of two high-pitched chimes. This specific sound is essential for maintaining communication protocols during critical phases of flight, such as takeoff and landing, when distractions need to be minimized and the flight crew must focus on their tasks. The use of chimes serves as a clear auditory cue that alerts both the flight attendants and the cockpit crew about the status of the sterile flight deck, ensuring that all personnel are aligned with safety procedures. This standardized signaling helps to enhance safety and operational efficiency on board.
