Single-pointer VOR/LOC indicator used with VIR-350/351 Navigation radios. Similar to IND-350 but is mechanically improved with metal instead of plastic chassis.
The IND-350A uses a rectilinear meter movement, instead of pendulum, which makes it easier to read. The needle remains vertical throughout its range of travel, which helps the pilot to better determine the degree of correction needed to stay on course. The IND-350A does not contain a VOR/LOC Converter, which permits its use with a GPS.
