A passenger service unit (PSU) is an aircraft part that is located in the overhead panel above the passenger seats of an airplane’s cabin, above each row.
A PSU includes reading lights, loudspeakers for announcements, illuminated signs (to remind passengers to buckle up and refrain from smoking), air conditioning vents, and automatic oxygen mask deployment in the event of cabin depressurization.
Some aircraft also have buttons for calling for help, though these are sometimes mounted on the armrest. These are not present on older aircraft or on the smallest feederliners.
For two reasons: to organise a passenger service unit within the passenger cabin simply and to build such a unit such that all passenger service functions are included in one unit that is conveniently within reach of a sitting passenger.
In order to achieve a separation of the systems that are specific to the aircraft from those that are special to flight passenger seats, it is thus best to avoid merging service and comfort features or components into a flight passenger seat.
Additionally, to avoid positioning or organising these comfort and service elements in areas of the overhead compartment that might annoy other passengers and to put these PSUs as close as feasible to each seat without interfering with the features of the respective seat.
The Global commercial aircraft passenger service unit market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Airbus has chosen Astronics Corporation to offer Passenger Service Units (PSUs), a top supplier of cutting-edge technology for the worldwide aerospace, defence, and other mission-critical industries.
The new Astronics PSU will use the most up-to-date materials and technology to improve the passenger experience aboard Airbus, building on decades of Astronics experience designing cabin interiors.
These upgrades consist of a contemporary and updated industrial design, optimised passenger air outlets, the most recent LED lighting options, and other design advancements to save weight and satisfy programme objectives.
have a long history of offering innovative interior solutions to our clients who are commercial aircraft manufacturers. Airbus and Astronics have a longstanding partnership, and they are thrilled to be working with the Airbus teams to create cutting-edge technologies for the A220 program.
Airbus has chosen Collins Aerospace, a division of Raytheon Technologies Corp., to provide improved passenger service units (PSU) for the distribution of the new A320 Family Airspace cabin. The new Airspace cabin’s cutting-edge architecture and stylish design blend in well, offering a unified passenger experience across the family of aircraft.
Reading lights, air outlet valves, and call attendant lights are just a few of the passenger touchpoints that can withstand the strength and durability offered by the Collins PSU’s innovative composite materials. Simple installation and removal are made possible by the modular design’s ability to be simply adjusted for a variety of seat pitches.
A passenger service unit that offers weight savings, improved performance, and a clean design that fits effortlessly within the new A320 Family Airspace cabin is the result of years of cooperation and meticulous customization.
With the Collins PSU, airlines can easily connect with a variety of aircraft configurations and all PSU supply channels while providing passengers with a better flight experience. Collins has been a PSU supplier for the A320 series of aircraft for more than 20 years.
Collins is currently engaged in active collaboration with Airbus to examine potential new advancements and enhance the existing exceptional performance of the new passenger service units. To satisfy the demands of a fast changing global market and to address the most difficult problems faced by clients, Collins Aerospace has a broad range of capabilities, a comprehensive portfolio, and considerable expertise.
By providing vertically integrated systems with in-house design, production, and finishing skills, Astronics provides commercial applications for Passenger Service Units (PSU).
For the majority of PSU programmes, Astronics assumes complete ownership of new technology design, development, and qualification, including manufacturing and final assembly. The 737 Boeing Sky Interior (BSI) PSU was given to Astronics with complete design authority.
The selection of this design depended heavily on having in-depth knowledge of PSU systems and a history of productive collaboration. In terms of lower costs, lighter packages, and quicker deliveries, the PSU Project Team exceeded programme objectives.
The success of the programme was made possible through design for manufacture, specialised tooling, and tight collaboration.Astronics oversaw the design, qualification, and construction of the 737 BSI PSU’s structural, lighting, gasper air, electrical, and acoustic considerations, as well as the integration of the oxygen system (with numerous variants).
Astronics proposed design components for the least expensive, lightest solution while adhering to tight design guidelines. Special tooling was developed to streamline manufacturing operations. Process upgrades made in collaboration with The Boeing Company sparked creativity for the 737 BSI PSU programme.
The greater emphasis on making aircraft cabins more roomy can be linked to the growing preference for slimmer PSUs. As a result, numerous well-known suppliers have modified their PSUs to make them more svelte and aesthetically pleasing parts.
