Tug Alpha 1
Elevating Aircraft Pushback Efficiency through Cutting-Edge HMI Design
In my capacity as sole UX/UI Designer and HMI Engineer for the Tug Alpha 1 project at Textron GSE, I was instrumental in redefining the aircraft pushback's electrical and human-machine interfaces (HMI). Employing a blend of visual and interaction design skills, complemented by block-based coding, I crafted a forward-thinking and highly functional HMI. This interface not only elevated the visual appeal but also significantly enhanced the usability and user experience, marking a substantial leap forward in design excellence compared to its forerunners.

Goal
Value
-
Objective: Redesign the Human-Machine Interface (HMI) for the Alpha 1 aircraft pushback vehicle to enhance usability and visual appeal.
-
Strategy: Employ a user-centered design approach, integrating user feedback and iterative design reviews to develop a modern, intuitive interface.
-
Benefit: The new HMI design simplifies operations, making it easier for users to control the pushback vehicle. The interface allows users to see system warnings and current levels of critical systems (such as voltage, PSI, and more), facilitating faster diagnosis and reducing maintenance time.
-
Impact: The improved user experience leads to increased efficiency and safety in airport ground operations, enhancing overall customer satisfaction and potentially reducing operational costs for Textron GSE. Additionally, the advanced HMI becomes a marketable feature, providing Textron GSE with a competitive edge in the industry. By guiding users through critical operational data more efficiently, the interface contributes to better maintenance practices and prolonged equipment lifespan.
