Because the needle remains vertical throughout its range of travel, the pilot can better determine the degree of correction needed to stay on course. The KI 203 also has warning flag, to-from indicator and an omnibearing selector (OBS). Chose the optional course datum synchro to link the KI 203 to a compass system such as the KCS 55A.
This option saves the pilot from continually manually adjusting the degree of correction.
Use the KI 203 with the KN 53 navigational receiver and the KX 155/155A/170/175 series NAV/COMMs.
Comes internally lit with a metal bezel and a glass lens. TSOd.
