AI Technical Summary

Technical Problem

In the existing technology, the ground calibration of the magnetic compass of light sport aircraft requires a large area and is prone to angular deviation, and it is impossible to accurately rotate the fuselage for calibration without starting the engine.

Method used

A magnetic compass calibration stand was designed, which includes a calibration platform base and an aircraft load-bearing platform. The aircraft load-bearing platform is rotated by a circular track and pulleys. Combined with landing gear positioning components and a level, the aircraft can rotate its fuselage without starting the engine, and data is recorded and calibrated using calibration scales.

Benefits of technology

It enables precise rotation of the aircraft fuselage to complete efficient calibration of the magnetic compass heading angle without starting the engine, avoiding site limitations and angle deviations.
