Maintenance Checklist Projector

Abstract

The Maintenance Checklist Projector has been developed and built as a portable, handheld device which is designed to project aircraft maintenance manuals and checklists directly onto working surfaces to improve efficiency and accuracy in maintenance work and operations. The projector is constructed with a lightweight ABS cylindrical housing for ergonomic handling, the device also incorporates with a rechargeable lithium-ion battery to ensure long operating hours without direct external power supply. Moreover, this projector integrates with a touchscreen user interface panel for intuitive navigation, while a Raspberry Pi 4B control system acts as a processor that controls data storage, power distribution, and real time projection of maintenance procedures. This projector is capable to ensure ergonomic handling and compliance with aircraft maintenance standards with development of hinges, vents and mounting systems for projector positioning. Moreover, it is programmed with Python for an interactive user interface to organize, search, and display documentation efficiently. The projector is fixed with a retractable stand for stability and user comfort in various environments. The output of this Maintenance Checklist Projector is to project a clear visual documentation with a good clarity to improve user readability. As a significant result, this projector can reduce human error, turnaround time and also paper usage. This innovation also supports regulatory compliance, sustainability goals and aligns with the aviation industry’s digital transformation efforts. The Maintenance Checklist Projector will also demonstrate potential adaptability for other technical industries such as the mechanical engineering field that requires a portable, real time guidance in procedures with demanding environments.
