Localizer or VOR-based Approaches
The AXIS™ automatically switches the external CDI output from GPS to VLOC as you intercept the final approach course. When the ILS approach activates and the correct ILS frequency activates in the VLOC window, the AXIS automatically switches to VLOC within 1.2 NM left or right of the final approach course. This switch can take place anywhere from 2.0 to 15.0 NM from the FAF.
