A passenger service unit (PSU) refers to an essential component found in various modes of public transportation and aviation. It is primarily designed to enhance the comfort, convenience, and safety of passengers during their journey. The PSU is typically installed above passenger seats or overhead compartments.
This modular unit integrates several crucial features and amenities. It typically includes reading lights, air vents, oxygen masks, call buttons, speaker systems, and sometimes even video screens for in-flight entertainment. Furthermore, it may contain important safety equipment like a fasten seatbelt sign, no smoking sign, and emergency oxygen masks in the event of decompression.
Passenger service units are crucial in maintaining a pleasant, well-organized, and safe environment within a vehicle or aircraft. These units provide passengers with personalized control over their immediate surroundings, allowing them to adjust lighting, air flow, and other amenities based on their preferences. The PSU ensures that passengers have quick access to essential services during the journey, such as requesting assistance from the cabin crew or obtaining reading light for their comfort.
The design and functionality of the PSU may vary depending on the mode of transportation and the airline or company providing the service. However, its primary objective is to enhance passenger experience and address their comfort and safety needs throughout the journey.
