KI-229 Radio Magnetic Indicator

The King KI-229 Radio Magnetic Indicator (RMI) combines three data points on one indicator. The current aircraft heading from an HSI is shown on the card. The magnetic headings to VOR and NDB stations are shown by the twin needles. By combining all this information visually, less interpretation is required. This boost in your overall situational awareness is especially helpful when the workload is high. The TSO'd KI-229 requires the following inputs:

ADF: King KR-87
HSI: King KCS-55/55A (or ARINC input required)
NAV Receiver: KN-53, KNS-80, KNS-81
