According to the abstract released by the Intellectual Property India: "Runway overrun is one of the most critical safety concerns in aviation, often caused by excessive landing speed, reduced braking efficiency, wet or contaminated runway surfaces, and delayed pilot response. Despite the presence of onboard systems and air traffic control monitoring, real-time runway condition awareness and stopping distance prediction at the ground level remain limited. This project proposes the design and development of a Smart Runway Overrun Alert System (SROAS) that provides real time monitoring and early warning to prevent runway excursion incidents. The proposed system integrates multiple sensors, including an ultrasonic sensor for aircraft speed estimation, a moisture sensor for runway surface condition detection, and a temperature sensor for environmental monitoring. These parameters are processed using an Arduino-based embedded system, which calculates the required stopping distance and compares it with the available runway length. When unsafe conditions are detected, the system generates visual alerts through an LCD display and transmits warning messages via a GSM communication module to the airport control system. A predictive algorithm is implemented to evaluate braking performance based on speed, runway condition, and friction estimation. The system operates in real time and provides immediate alerts when the calculated stopping distance exceeds the safe limit. Experimental testing was carried out under different simulated runway conditions such as dry, wet, and contaminated surfaces. The results demonstrate that the proposed system can effectively identify overrun risk scenarios and provide timely warnings, thereby improving runway safety. The SROAS is a low cost, scalable, anp easily deployable solution suitable for small and medium airports where advanced runway monitoring systems are not available. The system enhances situational awareness, supports safer landing operations, and contributes to the reduction of runway excursion accidents. Future enhancements include integration with machine learning models, cloud-based data logging, and direct communication with aircraft avionics for automated safety advisories.
