What types of heading and GPS inputs will the KMD-550/850 MFDs accept?
The KMD-540 display used in the KMD-550 and KMD-850 Multi Function Display systems is capable of receiving magnetic from several sources. This heading information is used to correct the difference between heading and track based display pages to allow overlay of flightplan information and other data. Compatible heading sources include synchro XYZ, FMS/HDG, Traffic ARINC 429, digital heading via WX-500 Stormscope. According to the KMD-550/850 installation manual, synchro XYZ is the highest priority heading source. However, the KAC-504 traffic PCMIA card must be installed in the KMD-540 base unit for the XYZ heading to operate. Therefore, this card must be installed in the KMD-540 display to interface common heading systems such as the Collins PN-101 and Bendix/King KCS-305 & KCS-55A. The cost of the KAC-504 traffic card is $2000 list price. Click Here to view a page from the KMD-550/850 installation manual detailing these interfaces (Adobe Acrobat Reader required).
