Abstract

Grob G 120 TP - A beta system aircraft is a system that regulates the size of the angle on the propeller. 42 failures occurred in the beta system from August 2016 to May 2021, resulting in the beta system having to be replaced even before reaching its 2500 flight hour age limit. Using the FTA (Fault Tree Analysis) method, which begins with defining the failure and determining the boundary conditions of the beta system, describing the fault tree model, identifying the minimum cut set from the fault tree, performing a qualitative analysis of the faults tree, and doing a quantitative analysis of the fault tree, it can be seen that the failure that often occurs in the beta system of the Grob G 120 TP-A aircraft is the occurrence of high oil temperature over 84 ℃, the qualitative analysis found 12 causes of failure on the beta system, and based on quantitative analysis obtained probability the occurrence of beta system failure is 0.76363.

Abstract

This study presents the design and implementation of a low-cost aircraft orientation angle measurement system using the MPU6050 sensor and Arduino Uno microcontroller for educational applications in avionics. The system aims to simulate aircraft attitude angles—yaw, pitch, and roll—by integrating an inertial sensor module (MPU6050) with open-source hardware and software. The Arduino IDE was employed to acquire and process sensor data, while the Processing 3 environment was used to visualize the attitude motion in real time. The prototype was assembled and tested to evaluate its performance in detecting orientation changes across three axes. Experimental results demonstrate that the MPU6050-based system can accurately capture and display attitude variations without communication delay or signal error, providing a clear visualization of aircraft motion. The system’s simplicity, affordability, and open-source framework make it suitable for classroom demonstrations and laboratory exercises in avionics and control-system courses. Future improvements include the integration of Euler-angle computation and wireless communication to enhance mobility and data acquisition.
