The Weather Radar Function of the Bendix/King KMD 850 Multi Function Display allows for the display and control of several Honeywell weather radar systems. Weather Radar indicates the presence and strength of precipitation and is intended to allow the operator to avoid thunderstorms and associated turbulence. This Pilot's Guide Addendum describes the operation of the KMD 850 display for controlling the weather radar sensor. The general operation of the KMD 850 is described in the other sections of the KMD 550/850 Pilot's Guide.
Troubleshooting and error codes
| Fault/Status Indication | Slashed Legend Icon? | Description |

| BUSY VP | no | In a dual indicator installation, the other indicator is in "continuous mode" for more than 26 seconds. |
| ANT/TX FLT | no | Loss of Radar Configuration data |
| ANT FLT | no | Loss of antenna position |
| Tx FLT | no | Transmitter Failure (also indicated if the R/T has turned its transmitter off because the airplane is on the ground) |
