Which component is included in Passenger Service Units?

• A. Air vents
• B. Cockpit door control
• C. Oxygen mask in the seat pocket
• D. Seat belt sign only

Answer: (A)

The Passenger Service Unit is the panel above each passenger seat that provides personal amenities like a reading light, a personal air vent, a call button, and the oxygen mask. The air vents are included because they are an integral part of that unit, giving you control over your own cabin airflow. The cockpit door control isn’t part of the passenger panel—it’s located in the cockpit area. The oxygen mask is indeed part of the PSU, but it’s stored in the unit above the seat, not in the seat pocket, so suggesting it’s in the seat pocket isn’t accurate. The seat belt sign is an overhead indicator controlled from the flight deck, not a component of the PSU. So the air vents are what belongs to the PSU in this context.
