Smart Pitot Guard (SPG)

Abstract

The pitot tube is a vital aircraft component for airspeed measurement, and its obstruction can lead to critical flight safety risks. Conventional pitot tube covers, while functional, are often overlooked during pre-flight checks or prove inadequate in low- light and high-pressure environments. This project focuses on the design and evaluation of a Smart Pitot Guard (SPG) that integrates advanced materials and smart warning systems to enhance safety and usability. The methodology involved CAD-based conceptual design, prototype fabrication with polypropylene and vinyl composites, and Microbit programming to operate ultrasonic sensors, LEDs, and buzzers. A self-release mechanism activated by pitot heat was also incorporated to minimize human error. Results from simulations and preliminary testing demonstrate improved durability, visibility, and reliability in alerting ground crew, while the automated disengagement feature ensures operational safety, with 95% of respondents recommending its use. In conclusion, the SPG effectively reduces pitot blockage risks, lowers maintenance costs, and improves ground crew efficiency. Its adoption could set a new standard in commercial aviation safety, preventing foreign object damage and enhancing flight reliability.
