Capital Avionics™ CA-320A digital compass transmitter and CA-320B receiver comprise the Compass Correction System. The system doesn™t need an external heading reference for the alignment of a compass; the first of its of its kind according to the company. The technician is now able to perform all measurements by simply moving the aircraft over an open ramp area. Rendered obsolete are sight compasses, compass roses, and the skills needed to properly align an aircraft. The CA-320A is mounted in a convenient location on the test aircraft and aligned with the integral sight laser. The technician reads the magnetic heading on the CA-320B. With this system, one can turn a corner of a ramp into a personal compass rose. The receiver features an easy-to-read LCD display, wireless technology, and a high-performance battery. The transmitter features 0.5 degree accuracy/0.3 degree repeatability, integral sight laser, wireless technology, and a high-performance battery.
