This article analyzes the use of Remotely Piloted Aircrafts (RPA) in VOR (Very High Frequency Omnidirectional Range) flight inspection. Initially, tests were performed to check whether the Autopilot Positioning System (APS) met the regulatory requirements. The results of these tests indicated that the APS provided information within the standard regulations. A Hardware in the Loop (HIL) platform was implemented to perform flight tests following the waypoints generated by a mission automation routine. One test was performed without introducing disturbance into the proposed test platform. The other four tests were performed introducing errors in latitude and longitude in the APS into the platform. The errors introduced had the same characteristics as those measured in the initial tests, in order for the simulation tests to be as similar as possible to the real situation. The tests performed with positioning errors only did not lead to false misalignment detection. However, introducing positioning errors and a 4° VOR misalignment error, a misalignment of 3.99° was observed during the flight test. This is a value greater than the maximum one allowed by the regulations, and the system indicates the VOR misalignment. Five flight inspection tests were performed. In addition to the APS errors, tests with a modulation error were also conducted. Introducing a 4° VOR misalignment in conjunction with modulation error, a misalignment of 4.02° was observed, resulting in successful misalignment detection.

This work provides quantitative data related to the use of Lofstrand crutches, these data are the strengthapplied on the armrest to the contact surface, the angle of the crutch relative to its axis of origin.Modular sensors of magnetometer, gyroscope and accelerometer were used. The results presented are: the dynamic force variation in the order of 0 kgf to 50 kgf was measured by the Force Sensing Resistor (FSR) sensor indicating the convergence of the data with the theoretical reference. Another innovative contribution of this work is the geoprocessing during the walk of the user. Finally, the purpose of the system is to explore the use of the Canadian crutch for the walking response and consequent storage of the users data, providing a mapping for user walk.
