The BendixKing Honeywell KI-204 VOR/LOC/Glideslope Indicator is designed to operate with VHF navigational equipment (such as the KX-170, KX-170A, KX-170B, KX-175, KX-175B, KN-53, KX-155, KX-155A, KX-165A) to provide OMNI range or localizer information. The navigational information from the VHF receiver is converted to DC signals to drive the left-right needle, To-From indicator, a glideslope deviation needle, glideslope warning flag and warning flag. The OBS knob allows the pilot to select the desired radial from the VOR station. The KI-204 may or may not be equipped with a course datum synchro for autopilot use. The KI-204 operates in a temperature range of -15ºC to +55ºC with a maximum altitude of 50,000 feet. The KI-204 is 3.26 inches high, 3.26 inches wide, 7.16 inches deep and weighs 1.70 pounds.
