Design and Implementation of Aircraft Accidents Avoidance System During Towing Using Fuzzy Logic

Abstract

Aircraft ground accident can be quite costly to the airline, with both tangible and intangible costs, it was found that the accident percentage of aircraft towing equal to 38% of all ground damage incidents and it cost more than $100 million per year in direct cost, this issue will be solve in this thesis by designing system to avoid aircraft accident during towing, using fuzzy expert system with combination of collision detection unit to identify an accident before it happen, The system composed of two main parts, the first part is outside aircraft Arduino control circuit which can detect foreign object and react to it immediately by sending a signal to the second part which is inside aircraft Arduino control circuit to stop the aircraft. By using fuzzy logic program to set adequate amount of pressure depend on distance, aircraft speed and ambient temperature. At the end of research, we have acquired results of output pressure to prevent aircraft accidents during towing with gradations of pressure from minimum to maximum amount of aircraft brake system pressures.
