Don’t be afraid to experiment. We thank you for your decision to purchase a KMD 250 and wish you many happy and safe hours flying. The KMD 250 MFD is a panel mounted Multi-Function Display system that is available with an optional internal VFR GPS navigator.
Section 3 Traffic Avoidance Explains operation of TCAS I, TCAS II and TIS sys- System Operation tems as they pertain to the KMD 250. Refer to the TCAS I or TCAS II user’s manual for more informa- tion. Section 4 WX-500 Stormscope®...
This manual also provides an explanation of each of the individual dis- plays that the KMD 250 unit presents. The operating system of the Bendix/King KMD 250 keeps to a minimum the number of key presses necessary to activate the various functions, especially those most frequently used in the air.
When active, the description indicated in the label describes the key’s present function related to the displayed page. Whenever a new option is selected, a new display is shown along with its new key labels. This Rev 4 Aug/2007 KMD 250 Pilot's Guide...

To receive FIS WX products, an aircraft must be equipped with a com- patible VDL receiver (KDR 510) or XM receiver (KDR 610), dedicated VHF antenna or satellite antenna, and appropriate display (KMD 250). FIS VDL uses a one-way (ground-to-air) broadcast protocol. XM WX uses one-way (satellite network to air) broadcast protocol.
A single display can display only VDL weather or only XM weather, not both. This section describes the operation of the KMD 250 display and dis- cusses the proper use of the displayed data for strategic weather plan- ning.
