Part 145 repair station Trimec Aviation, based at Fort Worth Meacham International airport in Texas, has added a Capital Avionics CA-420 digital compass rose system to support its growing client base.

GM John Holland says: “It has become increasingly difficult and problematic to locate traditional compass roses at local airports to calibrate an aircraft magnetic compass. This new advanced CA-420 system is so accurate and intuitive; we find it to be a valuable tool for our customers, not to mention convenient. We also remind our customers that the magnetic compass needs to be recalibrated periodically, as suggested by the manufacturer. In addition, it needs to be recalibrated when the plane has a major component change, is relocated to a significantly different latitude or when it has remained idle for one year or more.”

The CA-420 compass rose system incorporates the latest technology and utilises an android tablet with Wi-Fi connectivity. Advanced magnetic sensors, processors and an RF communications link provide technicians with an innovative tool to align the aircraft compass quickly and accurately.
