Where is the 4-way beeper switch located?

• A. Pilot's collective and co-pilot's collective
• B. Throttle levers
• C. Instrument panel
• D. Rudder pedals

Answer: (A)

The control you’re testing is meant to be quickly and reliably reachable by either pilot. A 4-way beeper switch is placed on both the pilot’s and co-pilot’s collective so either person can activate or adjust the beeper without reaching away from the main flight controls. This enhances crew communication and response during alert situations, while keeping the hands on the primary controls. Other locations would slow access or mix functions with other controls: throttle levers are dedicated to engine power, the instrument panel houses displays and indicators, and rudder pedals are foot controls. None of those are as convenient or appropriate for an audible alert control as the collective.
