This project focuses on the implementation of fire protection systems in the Boeing 737-500 flight simulator and the execution of operational tests. It includes detection and extinguishing systems for engines, the auxiliary power unit (APU) and other critical areas of the aircraft. The applied methodology uses a quantitative confirmatory approach to validate the operability of the simulations on the fire protection system oriented to the training of aircraft maintenance technicians. The theoretical basis of the project includes an exhaustive review of the academic documentation of maintenance manuals and tests on the efficiency and effectiveness of the system implemented in training. This theoretical analysis provides a solid foundation for the tests and improvements implemented. Ultimately, the study confirms that the improved fire protection systems in the simulator closely replicate those in the real aircraft, significantly improving the practical training of aviation personnel. This ensures that technicians are better prepared to handle emergency situations in real world conditions.
