Which list reflects the components included in the PSU?

• A. FA Call Button; Loud Speaker; Air Vent; Fasten Seatbelt Sign
• B. No Smoking Indicator; Seat Locator Sign; Supplemental Oxygen Dispensing Unit
• C. FA Call Button; Loud Speaker; Air Vent; Fasten Seatbelt Sign; No Smoking Indicator; Seat Locator Sign; Supplemental Oxygen Dispensing Unit
• D. Seat Belt Sign; Emergency Light; Public Address Speaker; Oxygen Mask

Answer: (C)

The question tests what components are included in the Passenger Service Unit (PSU). The PSU is the overhead panel that contains passenger controls and indicators used during flight. It includes the FA call button for summoning flight attendants, the loudspeaker for announcements, the air vent for airflow, the Fasten Seatbelt Sign, the No Smoking Indicator, the Seat Locator Sign, and the Supplemental Oxygen Dispensing Unit. The option that lists all seven of these components is the correct one. The other options are incomplete or include items not part of the PSU. For example, omitting any of the PSU items or including Emergency Light or Oxygen Mask, which belong to other cabin systems, would not accurately reflect the PSU contents.
